Description

This Arista passive twinax copper direct-attach cable has an OSFP connector at each end and links two 400GBASE-CR8 ports at 400GbE. It is built for short-reach connections between switches, or between switches and servers or other devices with OSFP ports, within a rack or between adjacent racks.

The 1m length runs eight electrical lanes for a 400 Gbps data rate, with no active electronics in the cable. It is a passive design, powered through the host OSFP port, so it suits low-cost, low-latency links. The housing is 13.0 x 22.6 x 100.4 mm and the cable is rated for an operating case temperature of 0 to 70 C.

It is intended for Arista platforms with 400G OSFP ports and complies with IEEE 802.3 and the OSFP MSA. Longer OSFP-to-OSFP lengths of 2m and 3m are available in the same family.

Enquire with XS Network Tech for new or used pricing and availability.
