BERK-TEK | 10032479 LANmark-1000 Enhanced CAT6 Riser 1000ft 550MHz CMR UTP Ethernet Cable

BERK-TEK LANmark-1000 Enhanced CAT6 Riser Cable - 1000ft Pull Box

This BERK-TEK LANmark-1000 riser cable delivers enhanced Category 6 performance for backbone and riser runs that require a CMR-rated construction. Built on 23 AWG solid bare copper conductors with a cross-filler design, it is engineered for installers who need certified performance, clean terminations, and dependable long-term reliability in commercial riser pathways.

Performance & Construction

Characterized to 550 MHz, the cable comfortably supports applications extending to 250 MHz, including 2.5/5GBASE-T, 1000BASE-T, 100BASE-TX, and 10BASE-T. Four pairs are laid up around a cross-filler to maintain precise pair geometry and enhance crosstalk performance while keeping the cable easy to terminate.

Power over Ethernet Ready

Certified for IEEE 802.3bt PoE Types 1 through 4 (up to 100 watts), Cisco UPOE and UPOE+ (90 watts max), and Power over HDBaseT (PoH) at 95 watts max, this riser cable is suited for powering IP cameras, wireless access points, and other PoE endpoints.

Standards & Compliance

Compliant with ANSI/TIA-568.2-D Cat 6 and ISO/IEC 11801, UL 444 listed, ETL verified, and RoHS compliant. The CMR riser rating meets UL 1666 for vertical riser installations.
