D-Link Cat 6 UTP Patch Cord — 3 Metre Grey (NCB-C6UGRYR1-3)
The D-Link NCB-C6UGRYR1-3 is a 3-metre Cat 6 unshielded patch cord with 24 AWG bare copper conductors, PVC UL94V-0 jacket, and RJ45 plugs fitted with 30µ” gold-plated phosphor bronze contacts. It is verified compliant with TIA/EIA-568C.2 and IEC 60603-7-4 patch cord standards — ETL verified and CUL listed — and is designed as the equipment cord or work area cord component within a compliant Cat 6 channel. The grey jacket is consistent with the D-Link structured cabling range colour convention and standard rack identification schemes.
The NCB-C6UGRYR1-3 is part of the D-Link Cat 6 round patch cord family (NCB-C6UGRYR1-X), available in lengths from 0.5m to 5m. The 3-metre variant suits cross-rack equipment room patching, work area outlet-to-device connections, and mid-length rack runs where 1-metre cords fall short and 5-metre cords introduce excess slack.
Performance and Bandwidth
The D-Link Cat 6 patch cord exceeds TIA/EIA-568B.2 and TIA/EIA-568C.2 performance requirements as verified by ETL. It supports 250 MHz bandwidth and Gigabit Ethernet (1000BASE-T / IEEE 802.3ab) within a compliant Cat 6 channel, and is additionally rated for 550 MHz broadband video transmission — a performance headroom above the standard 250 MHz Cat 6 specification that provides signal quality margin on multimedia and AV-over-IP applications.
Supported applications include:
- 1000BASE-T — Gigabit Ethernet (IEEE 802.3ab)
- 100BASE-TX — Fast Ethernet
- 10BASE-T — Standard Ethernet
- 100VG-AnyLAN (IEEE 802.12) — Legacy 100 Mbps networking
- 550 MHz Broadband Video — AV-over-IP and multimedia applications
- Voice, T1, ISDN — Telephony and legacy WAN interface applications
- 155 Mbps and 622 Mbps ATM — Legacy wide area network applications
- Power over Ethernet (PoE) — Standard PoE (IEEE 802.3af) and PoE+ (IEEE 802.3at)
Conductor and Cable Construction
The NCB-C6UGRYR1-3 uses 24 AWG bare copper stranded conductors across four twisted pairs. Stranded construction provides the flexibility and bend tolerance required for patch cord applications — the cord tolerates repeated connection and disconnection cycles and re-routing through cable managers without the conductor fatigue that solid-core cable would exhibit under the same conditions.
Conductor insulation is high-density polyethylene (HD-PE), the same insulation material used on the D-Link Cat 6 solid horizontal cable — maintaining consistent dielectric properties across the full D-Link Cat 6 channel from horizontal run to patch cord.
The outer jacket is PVC rated to UL94V-0 — the standard vertical flame test rating for communications cables, confirming that the jacket self-extinguishes within defined limits when exposed to a flame source. Heat resistance is rated to a minimum of 60°C.
RJ45 Connector Specifications
The RJ45 plugs on the NCB-C6UGRYR1-3 incorporate several specific design parameters that affect long-term reliability in active patching environments:
30µ” gold plating — The contact surfaces are plated with 30 microinches of gold. Gold at this thickness resists surface oxidation across repeated mating cycles, maintaining low and consistent contact resistance over the cord’s service life. This is the standard contact plating specification for D-Link’s Cat 6 patch cord range.
Phosphor bronze contact blades — The contact blades are manufactured from phosphor bronze — a spring alloy that maintains consistent contact force across the 750 rated mating cycles without loss of spring tension. Contact force consistency directly affects electrical contact resistance at the plug-to-jack interface.
750 mating cycles — The connector is rated for 750 insertion and extraction cycles. This represents the standard durability rating for Cat 6 patch cord RJ45 plugs and exceeds the typical mating cycle count encountered in equipment room and work area patching applications over a standard installation lifecycle.
20 lbs (89N) cable-to-plug tensile strength — The cable-to-plug strain relief joint is rated to withstand 20 lbs of pull force before failure. This rating protects the conductor termination points within the plug from mechanical failure during cord handling and extraction from congested patch panels.
Polycarbonate (PC) UL94V-0 plug body — The plug body is moulded from polycarbonate rated to UL94V-0, providing flame retardancy consistent with the jacket material. The transparent housing of the plug body allows visual inspection of conductor alignment within the plug after termination.
500V AC dielectric withstanding voltage — Confirms electrical isolation between contacts meets UL safety requirements.
Channel Integration
The NCB-C6UGRYR1-3 functions as the equipment cord or work area cord component within a TIA/EIA-568C.2 Cat 6 channel. The standard channel permits a combined maximum patch cord length of 10 metres across both the equipment and work area ends. At 3 metres, this cord leaves up to 7 metres available for the complementary cord at the opposing channel end — providing practical flexibility for installations where the equipment room or work area cord requires a longer reach.
When used as part of a complete D-Link Cat 6 channel alongside the D-Link NCB-C6UGRYR-305 solid horizontal cable and D-Link Cat 6 keystone jacks and patch panels, the cord contributes to an ETL-verified, TIA/EIA-568C.2-compliant channel.
Ideal Users
- Corporate and Enterprise IT Teams — The ETL-verified TIA/EIA-568C.2 compliance of the D-Link patch cord supports channel certification documentation on commercial installations where patch cord performance verification is part of the handover scope. Phosphor bronze contacts and 30µ” gold plating provide reliable connectivity across the patching activity levels typical of enterprise equipment rooms and distribution frames.
- Structured Cabling Contractors Specifying D-Link Channels — Pairing the NCB-C6UGRYR1-3 with D-Link solid Cat 6 horizontal cable, patch panels, and keystone jacks maintains single-vendor channel consistency across the full installation — simplifying procurement, installation documentation, and post-handover warranty coverage. The 3-metre length covers the equipment room cross-connect range most commonly needed between panel and switch positions.
- SME and Mid-Market IT Infrastructure Managers — For organisations managing their own network racks and equipment rooms, the D-Link Cat 6 patch cord provides verified Gigabit performance and PoE compatibility at a straightforward price point, backed by D-Link’s support infrastructure. The grey colour is consistent with D-Link’s Cat 6 cable range, supporting visual consistency in D-Link-based installations.
- Data Centre and Server Room Operators — The 3-metre length suits cross-rack connections and inter-panel patching in equipment rooms where switch and panel positions span more than a single rack bay. The 750 mating cycle rating and phosphor bronze contact durability support the connection and reconnection activity in active environments.
- AV and Multimedia Network Installers — The 550 MHz broadband video rating on the NCB-C6UGRYR1-3 makes it appropriate for AV-over-IP patching applications — connecting AV encoders, decoders, and matrix switches within structured cabling channels — where signal quality margin above the standard Cat 6 250 MHz specification is beneficial.
