How to Choose Your RJ45 Patch Cords: Technical Guide for Structured LAN Cabling

RJ45 patch cord: from the Permanent Link to the last metre in the patch panel every technical criterion counts Designing a structured LAN network means making decisions whose consequences last 15, 20, or even 30 years: cable category, shielding, cable and outlet identification, patch management. The Permanent Link, the fixed section between the patch panel and the wall outlet, represents a significant investment whose performance determines long-term network operations. Alongside with it, RJ45 patch cords are the mobile elements, replaced more frequently, and yet critical for Ethernet transmission quality, patch panel maintainability, and the daily comfort of a network admin or a low-voltage installer. This technical guide is designed for professionals who specify, purchase, or install RJ45 patch cords: IT network admins, design offices, low-voltage integrators, IT hardware distributors. It covers each genuinely discriminating criterion point by point: ISO/IEC 11801 or TIA/EIA-568 category, shielding (U/UTP, U/FTP, F/UTP, S/FTP), diameter and AWG gauge, POE++ (4PPoE) compatibility, and luminous identification systems, with a concrete recommendation at the end of the article. 1. Start with the Permanent Link: 15 to 30 years of investment to secure The Permanent Link, the horizontal cable between the patch panel and the wall outlet plus the associated connectors, is not a consumable. It is designed to remain in place for 10, 15, or even 30 years. This justifies investing in the best cable and outlet quality compatible with the project budget. As early as the 2000s, some companies installed CAT 7 cables even though outlets were still only CAT 6. The goal was to secure future bandwidth at 600 MHz and 10 Gb/s on a cabled infrastructure that would not be removed for a long time. The PiMF S/FTP cable is the archetype of this choice, and those installations are still operational today, running as CAT 6A 10 Gigabit, more than 25 years after installation. Today, the most common standard for a Permanent Link remains CAT 6A (100 m, 10 Gb/s, 500 MHz). CAT 7 in the Permanent Link, paired with CAT 6A RJ45 patch cords, is the premium choice for performance and investment lifespan. CAT 7 uses proprietary connectors (GG45 or TERA) that are rarely found on active equipment, making this option difficult to implement in standard enterprise LAN networks. CAT 8 (2,000 MHz, 25-40 Gb/s over 30 m) is reserved for short datacenter links and has the advantage of using RJ45-type connectors, compatible with all commercially available active equipment. Permanent Link cable category summary Category Max. frequency Ethernet throughput Distance Typical use CAT 6 250 MHz 1 Gb/s (10 Gb/s over 30 m) 100 m Legacy installations, tight budgets CAT 6A 500 MHz 10 Gb/s 100 m Current Permanent Link standard CAT 7 (ISO) 600 MHz 10 Gb/s with margin 100 m Premium choice for Permanent Link paired with CAT 6A cords. Full CAT 7 requires GG45/TERA CAT 8 2,000 MHz 25-40 Gb/s 30 m Datacenter, short links, RJ45 connector   Key takeaway: for a new Permanent Link, the rational target is CAT 6A. For a project with high long-term value requirements over 20 years, CAT 7 remains a valid choice for the Permanent Link paired with CAT 6A RJ45 patch cords. 2. ISO/IEC 11801 or TIA/EIA-568 category: two standards, one vocabulary to master Two standards coexist to define the performance of passive components in a LAN network. The European standard ISO/IEC 11801 uses classes (Class A to Class I). The American standard TIA/EIA-568 uses categories (Cat 1 to Cat 8). Both standards describe the same performance families under different nomenclatures: CAT 6A TIA corresponds to ISO Class EA, CAT 8 TIA corresponds to ISO Class I. CAT 7 ISO has no direct TIA equivalent, because TIA-568 only covers standard RJ45 patch cords. CAT 7 and CAT 8.2 use proprietary GG45 or TERA connectors. In the purchasing volumes of network admins in 2026, CAT 5e now represents only a residual share. The bulk of the RJ45 patch cord market is concentrated on categories 6 and 6A, with a clear shift towards CAT 6A driven by 10 Gb/s deployments and POE++ (4PPoE) compatibility. TIA/EIA ISO 11801 Max. freq. Throughput Cable type Use Cat 5e Class D 100 MHz 1 Gb/s U/UTP / F/UTP Residual installed base Cat 6 Class E 250 MHz 1 Gb/s U/UTP / U/FTP / F/UTP Standard LAN Cat 6A Class EA 500 MHz 10 Gb/s U/UTP / U/FTP / S/FTP Current LAN patch cord standard Cat 7 (ISO) Class F 600 MHz 10 Gb/s + margin S/FTP GG45 / TERA, Permanent Link premium Cat 8 Class I 2,000 MHz 25-40 Gb/s U/FTP / S/FTP Datacenter, short 30 m links   Operational tip: if your Permanent Link has remained at CAT 5e or CAT 6, replacing the connection cords and patch cords with CAT 6A noticeably improves the overall link performance without touching the horizontal cabling. 3. RJ45 patch cord shielding: U/UTP, U/FTP, F/UTP, S/FTP The shielding of an RJ45 cable protects the twisted pairs against electromagnetic interference (EMI): disturbance from a nearby 220 V mains cable, transformer radiation, variable-speed drives, fluorescent tubes, motors. In theory, a shielded cable maintains better signal quality and reduces frame losses. In practice, the choice is made according to several combined criteria. The rational first step: align the shielding of the RJ45 patch cord with the Permanent Link. If the horizontal cabling is laid as unshielded U/UTP, as is the rule in the United States, the United Kingdom, Ireland, Spain, Italy, and the majority of Benelux, then U/UTP patch cords are the natural choice. Shielding patch cords on an unshielded infrastructure adds nothing and unnecessarily clutters the patch panel. Shielded and unshielded practices are partly cultural and vary by country: Germany (DE) and Austria (AT): overwhelming majority of shielded cabling (S/FTP, U/FTP, F/UTP). The philosophy is to systematically protect Ethernet frames against any interference. France (FR) and Switzerland (CH): approximately 70% shielded, 30% unshielded. Both approaches coexist depending on project managers. USA, UK, Ireland, Spain, Italy, Benelux (BE, NL): predominantly U/UTP. These markets rely on the Ethernet protocol, which retransmits frames not correctly received. Useful throughput is marginally affected, but end users practically never notice it. Over a total link of 100 m, if a single RJ45 patch cord of 2 to 5 m is not shielded, any electromagnetic disturbances only affect a very short fraction of the link, imperceptible in practice. The key argument on shielded infrastructures: a single earth connection, no ground loop. If both ends of the link are shielded and earthed, a slight potential difference may exist between the wall outlet earth and the switch earth. This difference creates a loop current that can degrade the signal and, paradoxically, generate noise. The recommended pragmatic rule on a shielded infrastructure is therefore: A single earth connection, at the wall outlet (on the user side). Shielded connection cord on the end-user side, for mechanical resistance to chair wheels and repeated bending. Unshielded U/UTP SLIM RJ45 patch cord on the rack side: earth continuity interrupted, no loop, optimal slimness. Result: controlled earth continuity, no ground loop, slimmer and more flexible patch cord, better-ventilated patch panel. Type Meaning Advantage Disadvantage Recommended use U/UTP Unshielded Slimmest, most flexible, most economical Susceptible to strong EMI Standard patch cord, majority of countries U/FTP Individually foiled pairs Very good NEXT/ANEXT immunity Stiffer than U/UTP High-performance LAN Permanent Link, datacenter F/UTP Overall foil screen, unshielded pairs Good external EMI immunity Lower internal crosstalk immunity Industrial environment Permanent Link S/FTP Overall braid + foiled pairs Maximum immunity Stiff, large diameter CAT 8 Permanent Link, critical EMI environments   4. Diameter and flexibility: why SLIM has become the standard in the patch panel? Any professional working in a patch panel knows that a slim and flexible RJ45 patch cord delivers compounding benefits: less space taken up in cable managers and guides, better readability of the patch panel face, better rack ventilation critical on POE++ switches dissipating several tens of watts, and faster interventions with less risk of disturbing adjacent cords. The final diameter of an RJ45 cable depends on three factors: jacket material, the presence or absence of shielding, and the AWG gauge (American Wire Gauge) that defines the copper cross-section of the conductors. The higher the AWG figure, the less copper, and therefore the slimmer the cable. A standard RJ45 patch cord is AWG 24; a SLIM cord goes down to AWG 26 or AWG 28. SLIM patch cords are patch cords with an external diameter under 4.0 mm. At equal CAT 6A performance, a standard cord measures approximately 6.5 mm in diameter (AWG 24) versus under 4.0 mm for SLIM. The volume saving in the rack is spectacular: SLIM cords occupy approximately three times less space than standard cords. They are also far more flexible, facilitating tight patching and reducing mechanical stress on connectors. Criterion Standard CAT 6A CAT 6A SLIM (ThinPATCH) U/UTP cable diameter 6.5 to 7.0 mm 3.8 mm U/FTP cable diameter 7.0 to 7.5 mm 4.5 mm AWG gauge AWG 24 AWG 28 Volume in rack 100% (reference) Approximately 33% Flexibility Standard Very high POE++ compatibility (4PPoE, IEEE 802.3bt) Yes Yes Rack ventilation Standard Improved   The ThinPATCH range from 3P Design is certified CAT 6A and compatible with 4-pair Power Over Ethernet systems, meaning POE++ (4PPoE) compliant with IEEE 802.3bt (Types 3 and 4, up to 90 W at source). This is decisive for powering WiFi 6 and WiFi 7 access points, high-performance IP cameras, advanced SIP phones, and low-power charging terminals. The transition from CAT 6A AWG 24 to CAT 6A AWG 28 slim requires rigorous dimensioning of twisted pairs and plug electrical contacts, which ThinPATCH meets within the framework of the standard. 5. RJ45 patch cord identification in the patch panel: the criterion that costs time on every intervention In a 42U patch panel concentrating more than 200 RJ45 cables in under one square metre, quickly identifying both ends of a patch cord is a daily challenge. Without an identification system, the classic scenario unfolds: progressive extraction of the cord from cable guides, manual finger-tracing, risk of error, and disturbance of adjacent cords. Paper or plastic labelling remains a partial solution: tedious to apply, quickly illegible from the front, requiring cable-by-cable reading. Colour-coded cords: first-level identification Colour-coded RJ45 patch cords enable first-level application coding: data, IP telephony, CCTV, access control, fire alarm, or geographic zone coding. The logistics constraint is real: stock references must be multiplied (one colour per length), which puts pressure on IT hardware distributors and network admins. Removable PatchCLIP colour clips: the flexible alternative A more pragmatic approach: removable colour clips that mount on the connector boots. 3P Design offers PatchCLIP in 16 colours, with two clips per cord, one at each end. PatchCLIPs serve a dual purpose: colour coding and protection of the RJ45 plug locking tab, which is often snapped during cord extraction from cable guides. A single cord stock, 16 codes available on demand, without multiplying references. PATCHSEE luminous identification system: find the other end without unplugging The most demanding challenge in a patch panel remains identifying the second end of an RJ45 cord: from the panel, where is it patched on the switch? From the switch, which workstation is using this port? Without an adapted tool, you have to pull on the cord and finger-trace it, with all the associated risks of error and disorganisation. The PATCHSEE system, patented by 3P Design, solves this cable management challenge without unplugging any cord. The principle: two plastic optical fibres bent at 180 degrees integrated into the connector and the RJ45 plug boot. The operator positions the light injection tool (the PatchLIGHT) against the rear of the boot at one end; the light exits visibly at the other end of the cord. No electrical current injected, no interference on the Ethernet twisted pairs, no impact on Return Loss or NEXT. 100% passive technology, compliant with ISO/IEC 11801 and TIA/EIA-568 standards. The PATCHSEE system equips the PATCHSEE, ThinPATCH, and DirectPATCH ranges, in lengths from 15 cm to 30 m. See our comparison between LED patch cords and "patchsee system" LED RJ45 patch cords: the active alternative, with reservations A decade after PATCHSEE appeared came electrically-powered LED RJ45 patch cords: cords with an external tool such as the saCon DualBoot that powers the LEDs via pins on the rear face of the connectors, and cords with an integrated button cell in the boot such as EVO. Three technical reservations must be kept in mind: To carry current between both ends, the manufacturer adds an electrical wire inside the Ethernet cable and uses the ground drain as the return conductor on shielded variants. This falls outside the framework defined by ISO/IEC 11801 and TIA/EIA-568 standards. The boots are wider than the RJ45 plug itself due to the LED housing, making them incompatible with high-density environments (48-port 1U switches, high-density patch panels). The removable colour clips are tiny (approximately 7x2x1.5 mm), barely visible in a loaded rack, and sometimes non-existent on models with an integrated cell. Boot marking: reference and length All PATCHSEE, ThinPATCH, and DirectPATCH cords carry the product reference for restock orders and the exact cord length on the boot. Valuable daily information: a cord marked 1.5 m stays in the same rack; a cord marked 10 m is probably going to an adjacent rack. 6. Use case summary: which configuration for which LAN network? On an unshielded U/UTP network architecture (USA, UK, IE, ES, IT, Benelux, part of FR/CH), the recommended choice in the patch panel is: U/UTP SLIM CAT 6A RJ45 patch cords with a 3.8 mm diameter (ThinPATCH range), AWG 28 gauge compatible with POE++ (4PPoE), integrated PATCHSEE luminous identification system, and PatchCLIP in 16 colours for application coding. On a shielded network architecture (DE, AT, part of FR/CH): a single earth connection at the wall outlet, shielded U/FTP connection cord on the end-user side for mechanical resistance, SLIM RJ45 patch cord in the rack (U/UTP ThinPATCH 3.8 mm or U/FTP ThinPATCH 4.5 mm depending on the site policy), PATCHSEE luminous identification and zone coding with PatchCLIP. This configuration ensures earth continuity without creating a ground loop, while keeping the patch panel well-ventilated and easy to operate. 7. Against the market alternatives: what differentiates ThinPATCH and PATCHSEE? Three main patch cord families coexist in LAN network cable management. Standard colour-coded CAT 6 and CAT 6A cords (all generalist brands) offer colour-only identification with a heavy logistics stock burden. LED RJ45 patch cords (saCon DualBoot, EVO) offer active luminous identification at the cost of normative compromises and mechanical constraints: wide boot incompatible with high-density equipment, electrical wires added inside the cable. Retractable cords such as PatchBox solve variable lengths between the switch and patch panel within a single rack, but not cord identification across the LAN network. The Ubiquiti ecosystem (UniFi: router, switch, WiFi access point, telephony) offers standard accessory patch cords without any luminous identification system. PATCHSEE and ThinPATCH are the only solution that simultaneously combines: certified CAT 6A, SLIM 3.8 mm U/UTP, POE++ 4PPoE compatibility, passive luminous identification compliant with ISO/IEC 11801 and TIA/EIA-568 standards, 16 PatchCLIP colour clips protecting the RJ45 plug tab, integrated bend radius strain reliever, and reference plus length marking on every boot. All this in lengths from 15 cm to 30 m with 30 cm steps up to 3 m. 8. Conclusion: the simple rule for choosing your RJ45 patch cord For any new structured LAN cabling project: on an unshielded architecture, U/UTP SLIM CAT 6A patch cords in the rack for smooth operations. On a shielded architecture, a single earth connection at the wall outlet, shielded connection cord on the user side, SLIM patch cord in the rack. In all cases, a luminous identification system to locate both ends without unplugging, and removable colour clips for application coding. The best way to test these choices on your own patch panel is to try them under real conditions.

RJ45 Patch Cord Identification: LED Patch Cord or PATCHSEE - Which Technology for Your LAN Network?

Identifying an RJ45 cable in a patch panel without unplugging it: the right technology makes all the difference In a LAN network cabinet concentrating more than 200 RJ45 patch cords in under one square metre, tracing the other end of a cable should not be a guessing game. And yet, for too many network admins and IT installers, it still is. Reliable LAN cable identification saves time on every intervention, reduces human errors, and keeps the patch panel manageable over the long term. For roughly twenty years, two technology families have shared the market for luminous-identification RJ45 patch cords: on one side, the passive optical solution PATCHSEE (plastic optical fibres, patented by 3P Design), on the other electrically-powered LED RJ45 patch cords. Both deliver immediate cable identification, but the technical differences are far from trivial. This guide details, for a professional audience, what really separates these two approaches: ISO/TIA standards compliance, high-density compatibility, color clips, injection tool, marking, PoE compatibility, and use cases in datacenters and enterprise LAN networks. Two luminous-identification RJ45 patch cord technologies: how do they work? PATCHSEE: two plastic optical fibres, 100% passive The PATCHSEE system, invented and patented by French company 3P Design, uses two Plastic Optical Fibres (POF) bent at 180 degrees inside the RJ45 connector and its boot. The technician places the light injection tool (the PatchLIGHT) at one end of the cable, against the rear of the boot; light travels through the optical fibre to the other end of the patch cord, where it exits visibly, without unplugging the patch cord, without any electrical current, and without interference on the Ethernet twisted pairs. This unique optical technology is built into the PATCHSEE, ThinPATCH, and DirectPATCH RJ45 patch cords, available in lengths from 15 cm to 30 m. LED RJ45 patch cords: luminous identification via electrical power LED RJ45 patch cords of the DualBoot® type (notably saCon) or with integrated button cells (the EVO range, for example) use a different principle: two LEDs, one at each end, housed in the boots of the RJ45 connectors. Power is supplied either via an external tool with LR41 button batteries that connect to electrical pins on the rear of the RJ45 connectors, or via a button cell integrated directly in the boot. To carry current between both ends, the manufacturer adds an electrical wire inside the RJ45 cable, between the twisted pairs. On a shielded cable (U/FTP, F/UTP, S/FTP), the ground drain is used as the return conductor. This is the technical point that raises a normative issue, detailed below. The real issue: compliance with ISO/IEC and TIA/EIA standards This is the most technically critical argument, and it is too rarely raised by IT hardware distributors. The structured cabling standards ISO/IEC 11801 and TIA/EIA-568 define precisely what an Ethernet RJ45 cable contains: four twisted pairs, and optionally a shield and drain for screened cables. No normative provision authorises the circulation of an additional DC current in an added conductor, nor the use of the drain as an electrical conductor for LED power supply. Adding an electrical wire to power LEDs, and using the ground drain to close the electrical circuit, therefore falls outside the framework defined by these standards. PATCHSEE, by contrast, is a 100% passive technology: the injected light travels only through dedicated plastic optical fibres (POF), completely independent from the Ethernet pairs and the drain. No interference is possible on network frame signals, and there is no risk to the ground continuity of a shielded cable. Key takeaway: a standards-compliant luminous-identification RJ45 patch cord is a passive cord. The LED RJ45 patch cord, by design, passes current through the cable, which neither ISO nor TIA validates.   High-density environments: PATCHSEE fits, DualBoot® does not In a modern datacenter or on a high-density switch (48 ports or more in 1U), every millimetre counts. PATCHSEE connectors are designed with boots aligned to the edges of the RJ45 plug: no lateral overhang, no overhang on the contact side. As a result, PATCHSEE and ThinPATCH patch cords insert without constraint into high-density panels and switches, including side-by-side ports. LED RJ45 patch cords must house the LED and its power contacts inside the boot, which forces a wider boot than the RJ45 plug itself. The direct consequence: LED cords of the DualBoot® type cannot be used in high-density environments. Two adjacent cords block each other, and the oversized boot forces against the neighbouring port. For any datacenter project, dense network cabinet, or 48-port switch, the choice of a high-density compatible luminous-identification RJ45 patch cord is therefore decisive. Color clips: first-level identification in the patch panel In an enterprise LAN network, first-level color coding remains indispensable to distinguish, for example, the data network, telephony, CCTV, access control, fire alarm, or simply to differentiate geographic zones. Two approaches exist: color-coded patch cords, or removable color clips that mount on the connector boots. PATCHSEE offers 16 colors of removable PatchCLIP, with a dual benefit: they remain visible even in a loaded rack, and they protect the RJ45 plug locking tab from breakage during extraction. Two clips per cord are enough to assign the RJ45 patch cord to an application or a geographic zone. On the LED RJ45 patch cord side, the bulk of the diode inside the boot forces manufacturers to use tiny clips (approximately 7x2x1.5 mm). In practice they are difficult to handle for an installer, and their visibility is very low once the rack is fully loaded. Some models (the EVO range with integrated button cell) simply do not offer removable color clips at all. Bend radius strain reliever: a network performance issue ISO/IEC 11801 and TIA/EIA-568 recommend securing RJ45 cables with hook-and-loop straps, never with plastic cable ties that pinch the cable. A pinch, a tight bend, or excessive curvature degrades the cable's electrical characteristics: Return Loss (RL) and Near-End Crosstalk (NEXT) collapse, and a certified CAT 6A cable drops in real performance to CAT 6, or even CAT 5e levels. The direct consequence on throughput: unstable 10 Gb/s, or a drop back to 1 Gb/s. PATCHSEE CAT 6 and CAT 6A RJ45 patch cords, and the ThinPATCH range, integrate a bend radius strain reliever at the boot exit. This protects the most sensitive zone of the patch cord, which is precisely the zone most mechanically stressed in an active patch panel. Light injection tool: PatchLIGHT versus button cell power supplies On the PATCHSEE side, the injection tool is called the PatchLIGHT. It is a 5-LED, 30,000-lux light source, available in three colors (red, green, white), with two modes (steady or flashing). It runs on rechargeable batteries; when flat, it plugs directly into a 220 V mains socket at the bottom of the rack and continues to function. It positions one-handed against the rear of the boot, and its cord with clip allows it to hang in the rack during an intervention. Three colors combined with two modes means multiple simultaneous identification operations are possible in a single patching session. Some technicians even use the torch function of their smartphone to inject light into the plastic optical fibre, which demonstrates how practical the technology is. LED RJ45 patch cords, by contrast, require LR41 button-cell power, batteries rarely found in a standard stock. Targeting the small electrical contacts on the rear face to connect the power source is more fiddly, especially when the cable is curved. And when the batteries run out, they need to be on hand. No mains alternative, no direct rechargeability. Marking, lengths, and stock logistics A final technical point, often underestimated: boot marking. All PATCHSEE, ThinPATCH, and DirectPATCH RJ45 patch cords carry the product reference (useful for reorder) and the exact cable length on the boot. This is also a valuable troubleshooting indicator: a cord marked "1.5 m" almost certainly stays in the same cabinet; one marked "10.0 m" is most likely going to an adjacent rack. For available lengths, 3P Design offers a 30 cm increment from 15 cm to 3.0 m, then 4.0 m and 5.0 m, and longer lengths up to 30 m. The goal is simple: keep patch panels well-ventilated, with no excess cable cluttering cable managers and impairing airflow. ThinPATCH CAT 6A slim: space saving and PoE++ (4PPOE) The ThinPATCH range pushes the logic further with a slim CAT 6A cable: U/UTP: 3.8 mm diameter U/FTP: 4.5 mm diameter PoE++ (4PPOE) compatible, meaning full 4-pair PoE up to the highest power classes The measurable benefits for a network admin or low-voltage installer: Significant space saving in patch cabinets, cable managers, and cable trays Greater ease of use during patching, maintenance, and troubleshooting Better rack airflow, reducing thermal stress on switches and lowering failure risk More flexible cable: easier patching and access, particularly on high-density panels ThinPATCH inherits the full PATCHSEE luminous identification technology and all PatchCLIP color options. Comparison table: RJ45 PATCHSEE vs LED RJ45 patch cord Technical criterion PATCHSEE / ThinPATCH (optical fibre) LED RJ45 patch cord(DualBoot® type saCon, EVO) Identification principle Passive plastic optical fibres Active electronic LED Light output POF: smaller illuminated surface, but sufficient LED: higher raw luminous power ISO/IEC 11801 and TIA/EIA-568 compliance Compliant (no added conductor) Not validated by standards (wire added, drain used) Interference on Ethernet pairs None Potential risk (current in cable) U/UTP (unshielded) compatibility Yes, all ranges Often no (DualBoot requires a drain) High-density environments Compatible (boot aligned with RJ45 plug) Not compatible (boot wider than plug) Removable color clips 16 colors, protect RJ45 locking tab Tiny (~7x2x1.5 mm), barely visible Bend radius strain reliever Yes, on CAT 6 and CAT 6A Rarely Injection tool / power source PatchLIGHT rechargeable + 220 V mains, 3 colors, steady/flashing mode LR41 button cells, not rechargeable, or integrated button cell Boot marking Reference + exact length Generally absent Slim CAT 6A range + PoE++ 4PPOE ThinPATCH 3.8 mm U/UTP / 4.5 mm U/FTP Not available in slim (LED bulk) Available lengths 15 cm to 30 m, 30 cm steps up to 3 m Range often more limited Which solution by country and LAN network type? Not all European markets use the same structured cabling. This point is critical for choosing the right product: Germany (DE) and Austria (AT): near-exclusive use of shielded LAN cable (U/FTP, F/UTP, S/FTP). Luminous-identification RJ45 patch cords must be available in shielded versions, which is the case for PATCHSEE. LED DualBoot® cords that require the drain can exist in shielded versions, but remain subject to the normative reservations above. France (FR) and Switzerland (CH): approximately 30% shielded cabling, 70% unshielded. PATCHSEE and ThinPATCH cover both. LED RJ45 patch cords of the DualBoot® type do not exist in U/UTP, which excludes the majority of installations. United Kingdom (UK), Ireland (IE), Spain (ES), Italy (IT), Benelux (BE, NL): predominantly U/UTP. Only passive solutions such as PATCHSEE and ThinPATCH allow reliable luminous identification on unshielded cable, since there is neither a drain nor a need for electrical power. International datacenters: regardless of the country, the high-density constraint alone decides. PATCHSEE and ThinPATCH pass. LED RJ45 patch cords with oversized boots do not. USA and Asia: predominantly U/UTP. LED cords requiring a drain are inapplicable. PATCHSEE and ThinPATCH are the only universal LAN cable identification solution. Positioning against market alternatives Several names come up when discussing cable management and luminous patch cords: saCon (DualBoot® LED cords, strong presence in DE/AT), EVO (LED cords with integrated button cell, no removable color clip), PatchBox (retractable patch cord solution, a different problem focused on space saving), Ubiquiti (UniFi ecosystem: router, switch, Wi-Fi access point, telephony, with accessory patch cords). None of these alternatives simultaneously combines: passive luminous identification compliant with standards, high-density compatibility, 16 color clips protecting the RJ45 plug, slim CAT 6A PoE++ range, reference and length marking. This is precisely the scope covered by the 3P Design product family (PATCHSEE, ThinPATCH, PatchCLIP, PatchLIGHT). To understand the complementarity between the PATCHSEE system and Ubiquiti, read our article "PATCHSEE vs Ubiquiti comparison". Summary: which luminous-identification RJ45 patch cord to choose for your LAN network? If your specification includes, even partially, any of the following points, the passive PATCHSEE / ThinPATCH solution is objectively the most appropriate: Full compliance with ISO/IEC 11801 and TIA/EIA-568 without exception, U/UTP LAN network (any country outside DE/AT majority usage), High-density patch panel, 48-port switch, datacenter, Color coding that is practical by hand and visible at distance in a loaded rack, PoE / PoE+ / PoE++ 4PPOE on slim cable, A light injection tool that is always available (rechargeable + mains). LED RJ45 patch cords retain one simple advantage, the raw luminous power of a diode, but in a standard network room (technical rooms with no direct sunlight), the light from a PATCHSEE optical fibre is perfectly sufficient for LAN cable identification in a few seconds. Testing before equipping an entire site is the best way to decide.
