Description

This passive twinax direct attach breakout cable connects a 200G QSFP-DD port to eight 25G SFP28 ports, rated 200GBASE-CR8 and 25GBASE-CR. At 2.5m in length, it suits short-reach links within a rack or between adjacent racks, allowing a single 200G port to fan out to multiple 25G server or switch interfaces. Passive copper construction removes the need for separate optics at each end.

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