BERK-TEK | RDT 11141650 CAT6A Plenum Blue 1000ft 750MHz REDUCED DIAMETER Ethernet Cable

The Berk-Tek RDT is a Category 6A plenum Ethernet cable that does something most Cat6A cables don't — it slims down to a 0.230" diameter without giving up any performance. That's noticeably smaller than the 0.260" average for Cat6A, and in high-density installations where conduit space and cable tray capacity are real constraints, that difference adds up fast. Made in the USA and independently verified by ETL as part of the Leviton Verified Performance Program, this cable is built for 10 Gigabit networks, full PoE++ support, and environments where both signal quality and physical installation efficiency matter.

Features and Applications

The headline feature here is the reduced diameter — and it's not just a marketing point. At 0.230", this cable improves tray-fill ratios in high-density pathways, which directly reduces the number of conduits and trays needed on a job. That means lower material costs and less installation time, especially on large commercial projects where hundreds of runs are being pulled simultaneously.

Berk-Tek achieves this slim profile by eliminating the traditional cross filler found in most Cat6A cables. In its place, Precision Twist Technology maintains consistent pair geometry throughout the cable, delivering enhanced transmission characteristics and reliable performance for 2.5G, 5G, and 10G applications. The cable also incorporates Leviton's FLX-1 technology for maximum flexibility and a tighter bend radius, making it easier to route through tight spaces and around corners without compromising signal integrity.

An isolation wrap surrounds the cable core, providing superior heat management — a critical factor in PoE installations, where multiple power-carrying cables can generate significant heat in bundled runs. The alien crosstalk performance exceeds Cat6A requirements by an 8 dB margin on both PSANEXT and PSAACRF, independently verified by ETL. Performance data is guaranteed up to 750 MHz, well beyond the 500 MHz Cat6A standard.

Uses

This cable is purpose-built for:

• 10GBASE-T, 5GBASE-T, and 2.5GBASE-T horizontal runs in enterprise, healthcare, education, and government facilities
• High-density cable tray and conduit installations, where reduced diameter directly improves pathway efficiency and lowers infrastructure costs
• IEEE 802.3bt PoE++ (Types 1–4) for powering wireless access points, IP cameras, digital signage, and VoIP phones
• 802.11ac wireless infrastructure backhaul cabling in dense Wi-Fi deployments
• HD video and IP security systems require reliable, low-noise signal transmission
• Plenum and air-handling spaces where CMP-rated, low-smoke cable is required by fire code

Construction

Each conductor is 23 AWG bare copper, insulated with thermoplastic. Two insulated conductors are twisted together to form a pair, and all four pairs are cabled together to form the core. Unlike conventional Cat6A cables, there is no cross filler — the pairs are held in position through Berk-Tek's Precision Twist Technology, which keeps electrical characteristics consistent from one end of the reel to the other. The core is wrapped with an isolation layer for heat management and noise reduction, then jacketed with a flame-retardant polymer alloy compound rated for plenum environments.

Colour coding follows the standard scheme: Pair 1 is White/Blue, Pair 2 is White/Orange, Pair 3 is White/Green, and Pair 4 is White/Brown. The print legend on the jacket reads: BERK-TEK RDT UTP 23 AWG CMP 105C C(ETL)US CMP-LP (0.7A) ETL VERIFIED TIA-568.2-D CAT 6A US7560646.
