The Berk-Tek LANmark-10G2 (Part Number 10137694) is a plenum-rated Cat6A UTP Ethernet cable designed for 10 Gigabit networks where performance margins genuinely matter. Manufactured by Berk-Tek, a Nexans company, this cable carries a unique factory guarantee: every reel must pass testing with a minimum 2 dB margin for NEXT and PSNEXT and 4 dB margin for ACRF and PSACRF beyond the Cat6A standard before it earns the LANmark-10G2 legend. It's a true multimedia cable built to handle voice, video, and data simultaneously across a single infrastructure, characterized to 750 MHz — that's 250 MHz beyond what the standard requires. Made in the USA, this green-jacketed 1000-foot reel is a make-to-stock item ready for immediate deployment.

Features and Applications
The LANmark-10G2 uses a patented design that minimizes alien crosstalk — the interference that bleeds between adjacent cables in tightly packed bundles — while keeping the outer diameter at a compact 0.300 inches. Its documented balance characteristics (LCL/TCL and EL TCTL) reduce transmission errors and improve overall signal quality. The cable supports a wide range of networking standards: IEEE 802.3an 10GBASE-T at 10 Gb/s, IEEE 802.3 1000BASE-T at 1 Gb/s, TIA/EIA-854 1000BASE-TX at 1 Gb/s, ATM at 155 Mb/s, CDDI at 100 Mb/s, and IEEE 802.3 10BASE-T at 10 Mb/s. Its reduced insertion loss delivers a stronger signal-to-noise ratio, and the bandwidth characterization to 750 MHz provides headroom well beyond the 500 MHz Cat6A minimum.
Uses
This cable is built for indoor plenum spaces — the air-handling areas above drop ceilings and below raised floors in commercial buildings where fire-rated cable is required by code. It serves enterprise office buildings, data centers, educational institutions, hospitals, and government facilities running converged networks that carry voice, broadband video, analog video, and high-speed data over a single cable plant. Network architects and contractors use it for horizontal runs, backbone connections, and any deployment where 10 Gigabit speeds need to be future-proofed with performance margin to spare.
Construction
The conductors are solid bare copper wire insulated with FEP (fluorinated ethylene propylene), a material chosen specifically for plenum environments due to its low smoke and flame characteristics. Two insulated conductors are twisted together to form each pair, and four pairs are cabled together to form the core. Three monofilaments are used to make the cable round — this isn't just cosmetic; the round profile provides a true, consistent outer diameter measurement that simplifies cable management and pathway fill calculations. The outer jacket is striated flame-retardant PVC, and the standard four-pair color code applies: white/blue with blue, white/orange with orange, white/green with green, and white/brown with brown.
Additional Information
The cable is ETL Listed and carries a Plenum (CMP) flame rating per NFPA 262. It complies with ANSI/TIA-568-C.2, UL 444, and international standard ISO/IEC 11801. It is also RoHS compliant under EU Directive 2002/95/EC. Part number 10137694 in green is a make-to-stock item.
