BERK-TEK | 11142454 RDT CAT6A Plenum 1000ft Blue 23 AWG UTP Ethernet Cable

The BERK-TEK RDT Cat6A UTP CMP Cable (Part No. 11142454) is a blue, 1000ft plenum-rated Ethernet cable engineered for high-density commercial and enterprise network environments. Its reduced outer diameter of just 0.230 inches noticeably slimmer than the 0.260-inch average for Cat 6A cables makes it a standout choice where pathway space is at a premium. Manufactured in the USA and independently verified by ETL (Intertek) through Leviton's Verified Performance Program, this cable delivers real-world performance that matches what's on the label, giving installers and network engineers one less thing to worry about on the job site.

Features and Applications

The slim design isn't just about fitting into tighter spaces — it directly improves tray-fill ratios and gives installers more routing flexibility in crowded conduit runs. Leviton's proprietary FLX-1 technology contributes to a tighter bend radius and smoother pulls, while Precision Twist Technology enhances transmission quality for 2.5G, 5G, and 10G network speeds in real-world deployments. The cross-filler-free construction reduces bend resistance, cuts down job site waste, and speeds up installation, which adds up to a more sustainable and cost-effective project overall.

The cable's isolation wrap manages heat effectively and minimizes signal interference — a genuine advantage in buildings running heavy PoE loads across hundreds of ports simultaneously. Performance exceeds the ANSI/TIA-568.2-D Category 6A standard by 8 dB on both PSANEXT and PSAACRF measurements, meaning it doesn't just meet the standard, it surpasses it. The Patented Profile Technology rounds out a well-thought-out design that prioritizes both installer experience and long-term network reliability.

Uses

This cable is built for:

• Enterprise and commercial LAN infrastructure
• High-density patch rooms, server rooms, and data centers
• 802.11ac wireless access point backhaul connections
• HD video surveillance and IP security camera systems
• PoE-powered devices supporting Types 1, 2, 3, and 4 (IEEE 802.3bt)
• 10GBASE-T (10 Gb/s), 2.5/5GBASE-T, 1000BASE-T, 100BASE-TX, and 10BASE-T applications

Construction

Each conductor is 23 AWG bare copper, individually insulated with thermoplastic. Two conductors are twisted together to form a pair, and four pairs are bundled together to form the cable core. An isolation wrap surrounds the entire core before a flame-retardant polymer alloy jacket is applied. There is no cross filler — a deliberate design choice that improves flexibility and reduces material waste. The finished jacket is CMP-rated and UL Listed as CMP-LP (0.7A), making this cable fully compliant with NFPA 70 for use in plenum air-handling spaces.

Color coding: Pair 1 (White/Blue), Pair 2 (White/Orange), Pair 3 (White/Green), Pair 4 (White/Brown).

This cable ships in Leviton's TEKPAK Boxes, designed for cleaner, tangle-free pulls that keep job sites moving efficiently. It is fully RoHS compliant and carries a UL CMP-LP (0.7A) listing. The smaller outer diameter also translates to lower shipping weight per reel and reduced warehouse footprint, cutting greenhouse gas emissions during transportation compared to standard Cat 6A cables — a small but real environmental win for large-scale deployments.
