Description

This passive twinax copper breakout cable connects a single 200G OSFP port to four 50G QSFP ports over a 3 metre run, using 200GBASE-CR8 to 4x 50GBASE-CR2 signalling. With no active electronics, it draws no power and adds minimal latency, making it well suited to short-reach links within a rack or between adjacent racks. Each connector includes a pull tab latch for easy removal.
