Description

Passive twinax copper breakout direct attach cable that connects one 200G OSFP port to eight 25G SFP28 ports over a 3 m length. The host OSFP port runs at 200G using 8 x 25G NRZ electrical lanes, making it well suited to short in-rack or adjacent-rack links between a leaf switch and multiple 25G servers. The passive copper design offers low power consumption and low latency, and interoperates with legacy 25G SFP ports.

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