Siemon Cat 6 UTP Pure Copper Ethernet Cable 305M (9C6M4-E3)

The Siemon Cat 6 UTP Pure Copper Ethernet Cable (9C6M4-E3) is a high-performance 305-meter (1000 ft) bulk cable designed for structured cabling in commercial and residential networks. Featuring 23 AWG solid bare copper conductors and a 4-pair unshielded twisted pair (UTP) design with a central isolation member, this cable ensures minimal signal loss, superior conductivity, and enhanced crosstalk protection. Ideal for LAN, VoIP, CCTV/IP surveillance, and PoE applications up to 90W, it meets and exceeds Category 6/Class E standards for reliable, future-ready network performance.

Product Features

High-Speed Network Performance

Supports bandwidths up to 250 MHz and speeds of 1 Gbps over 100 meters, with short-distance support for 10Gb/s up to 55 meters, enabling high-speed data transmission for enterprise and residential networks.

Solid Copper Conductors

Constructed with 23 AWG solid bare copper, providing superior conductivity and lower signal attenuation compared to Copper Clad Aluminum (CCA) alternatives.

Optimized Pair Geometry

Includes a central cross-shaped isolation member (spline) to maintain pair separation, reduce near-end crosstalk (NEXT), and ensure consistent electrical performance.

Durable Lead-Free PVC Jacket

The grey lead-free PVC jacket offers mechanical protection while allowing flexible installation. Reverse sequential numbering allows easy tracking of remaining cable length.

Wide Compatibility

Fully compliant with ISO/IEC 11801, ANSI/TIA-568-C.2, and UL verified, making it suitable for structured cabling systems and future-proof network deployments.

PoE Support

Supports IEEE 802.3af/at/bt for Power over Ethernet (PoE) applications up to 90W, enabling networked devices to operate without separate power sources.
