Description

This passive 400GBASE-CR8 twinax copper direct attach cable has OSFP connectors on both ends and a length of 2 metres. It carries 400G over 8 x 50G PAM4 lanes and is designed for short-reach links between OSFP ports on switches, servers and NICs. The 2m OSFP to OSFP configuration suits adjacent rack and top-of-rack deployments where a low-cost copper interconnect is preferred over optics.
