Description

This Arista 25G SFP28 direct attach cable is a passive twinax copper assembly with SFP28 connectors on both ends, delivering 25GBASE-CR connectivity over a 2 metre run. It suits short-reach top-of-rack links between switches and servers in data centre environments. As a member of the CAB-S-S-25G family, the 2m length provides a cost-effective, low-latency alternative to optical transceivers for in-rack and adjacent-rack connections.
