Breakout Cables

A physical 4X HDR switch port can be split into two independent HDR100 ports. This is analogous to Ethernet port splitting, for example, converting a 4-lane 100 GbE port into four 25 GbE connections. HDR-to-dual-HDR100 breakout cables, or splitters, are available for this purpose, with QSFP connectors on all three legs (Figure 4).

Splitter cables are available for both optical and copper cables.
