Dlink Cat 6 Cable Copper Indoor

D-Link Cat 6 UTP Copper Indoor Cable — 305m Reel (NCB-C6UGRYR-305)

The D-Link NCB-C6UGRYR-305 is a 23 AWG solid bare copper Category 6 UTP cable for fixed indoor structured cabling installations. It is manufactured to exceed the performance requirements of TIA/EIA-568C.2 and ISO/IEC 11801 Class E standards at 250 MHz, supporting Gigabit Ethernet (1000BASE-T) across the full 100-metre horizontal channel. The cable is ETL verified, CUL listed, and RoHS compliant, and is supplied on a 305-metre reel in grey.

D-Link is a globally established networking manufacturer with a structured cabling product line spanning switches, access points, and LAN cable. The NCB-C6UGRYR-305 is part of D-Link’s structured cabling solutions range — a Cat 6 solid cable designed for LAN infrastructure deployments in commercial offices, data centres, and enterprise environments where Gigabit connectivity and standards-verified performance are required at a straightforward price point.

Performance and Bandwidth

The D-Link Cat 6 cable is rated to 250 MHz and exceeds TIA/EIA-568C.2 Category 6 performance requirements across the full transmission parameter set. Verified electrical performance at 100 metres includes insertion loss of 19.8 dB, NEXT of 44.3 dB, PS-NEXT of 42.3 dB, ELFEXT of 27.8 dB, and ACR of 24.5 dB — all tested and verified by ETL against TIA/EIA-568C.2 limits, not just self-declared.

The cable supports the following Ethernet standards across a compliant 100-metre channel:

• 1000BASE-T — Gigabit Ethernet (IEEE 802.3ab) at full 100m channel
• 100BASE-TX — Fast Ethernet
• 10BASE-T — Standard Ethernet
• 10GBASE-T — 10 Gigabit Ethernet over shorter runs (approximately 55m channel)

The characteristic impedance of 100Ω (±15%) and nominal velocity of propagation of 69% are consistent with standard Cat 6 channel design parameters. Mutual capacitance of 5.6 nF/100m nominal and delay skew below 45 ns support VoIP, video streaming, and multimedia applications across the LAN without timing-induced signal degradation.

Cable Construction

The D-Link Cat 6 cable is built from the following components:

Conductors — 23 AWG (0.560mm nominal) solid bare copper, providing the lower attenuation per metre and correct IDC termination characteristics required for permanent horizontal fixed runs. Conductor resistance is below 9.38Ω/100m, with resistance unbalance not exceeding 5% — parameters that directly support reliable PoE power delivery alongside data transmission. Capacitance unbalance is controlled to below 330pF/100m, maintaining signal balance across the channel.

HD-PE insulation — High-density polyethylene insulation surrounds each conductor with a nominal insulation diameter of 0.970mm. HD-PE provides consistent dielectric properties across the operating temperature range, contributing to the stable impedance and velocity of propagation that Cat 6 performance at 250 MHz requires.

PE central cross separator — A polyethylene cross-filler maintains physical separation between the four twisted pairs, preserving pair geometry throughout the cable and reducing pair-to-pair crosstalk at high frequencies.

PVC UL94V-0 jacket — The outer jacket uses PVC compound rated to UL94V-0 — the standard vertical flame test rating for communications cables. This rating confirms that the jacket material self-extinguishes within defined limits when exposed to a flame source, meeting NEC and UL safety requirements for general indoor wiring. The cable diameter is 6mm nominal, and the jacket is grey — consistent with standard structured cabling colour conventions.

An LSZH jacket variant (NCB-C6UGRYR-305-LS) is available where halogen-free materials are required by project specification or building fire regulation.

Standards Compliance and Third-Party Verification

The D-Link Cat 6 cable is verified compliant with TIA/EIA-568C.2 by ETL — an independent third-party testing and certification body. ETL verification is a meaningful distinction from self-declared compliance: the cable has been tested by an accredited laboratory against the full TIA/EIA-568C.2 parameter set, and the results confirm that it meets or exceeds all Category 6 requirements. Furthermore, CUL listing confirms compliance with Canadian electrical safety standards under UL 444 for copper conductor communications cables.

This level of third-party verification supports structured cabling channel certification — a project deliverable on commercial fit-outs where the horizontal cable must be certified to Cat 6 performance as part of the installation handover documentation. Cables with only manufacturer-declared compliance cannot provide the same assurance in a third-party certified channel.

PoE Support

The D-Link Cat 6 cable supports PoE applications across a compliant channel. The solid bare copper conductors and controlled conductor resistance (below 9.38Ω/100m) provide the low DC resistance required for reliable PoE power delivery to connected devices. The cable supports:

• PoE (IEEE 802.3af) — Up to 15.4W per port
• PoE+ (IEEE 802.3at) — Up to 30W per port
• PoE++ (IEEE 802.3bt) — Up to 90W per port on compliant channel designs

For high-power PoE++ applications at longer run lengths, conductor temperature rise under sustained current load should be factored into channel design — particularly in dense cable bundles where heat dissipation is reduced. This is a channel-level consideration applicable to all Cat 6 cable, not specific to the D-Link product.

Installation Characteristics

The D-Link Cat 6 cable is supplied on a 305-metre reel. Maximum pulling force is 11.5kg, and minimum bend radius is four times the cable outer diameter during installation. The 6mm nominal outer diameter is consistent with standard Cat 6 cable sizing, compatible with standard conduit fill calculations, cable management finger ducts, and keystone jack termination tooling.

The cable terminates into standard Cat 6 keystone jacks, patch panels, and RJ45 field plugs using standard 110-style IDC tooling. No specialist equipment is required. The operating temperature range of -20°C to +70°C covers the full range of indoor building environments from unheated roof voids to climate-controlled data centres.
