Arista Networks CBL-10139-20 Twinax Copper Cable

Arista CBL-10139-20 Twinax copper cable is a 10GBASE-CR direct-attached copper cable that provides point-to-point connectivity between SFP ports in data center networks. The assembly is 0.5 meters long and preterminated with SFP connectors on both ends, designed for use with SFP+ ports to carry 10 Gb/s Ethernet over copper for short-reach interconnects in dense rack environments to minimize cable clutter and bend radius. This cable belongs to Arista's line of 10GBASE-CR twinax DACs, offered in multiple lengths including 0.5 m, 1 m, 1.5 m, 2 m, 2.5 m, 3 m, and 5 m, to support a range of rack and data-center topologies. In practice, it is intended for inter-device links such as switch-to-switch or switch-to-server connections within racks, including top-of-rack and spine-leaf deployments, helping simplify routing when deploying Arista gear that supports 10GBASE-CR DAC cables.
