Description
The QSFP-4SFP25G-CU5M is a passive breakout copper cable, 5 m long. Cisco's 100GBASE QSFP-100G data sheet lists it in the passive copper breakout table. Check the host platform's supported-cable list before deploying, as support varies by switch family and software release. Choose it for rows of cabinets where the cable must leave one rack, cross a short gap and enter the next. It lets a single 100G switch port serve four 25G servers or NICs, reducing the leaf ports needed per rack. One end is a 100G QSFP28 connector, and the other splits into four SFP28 connectors, each carrying one 25 Gigabit Ethernet lane. Store unused lengths coiled loosely in their bag so the jacket and strain reliefs keep their shape. Both connector ends use the same housing style, so the cable has no preferred direction when installed. The cable is a single sealed assembly, supplied as the spare part number with the equals suffix.
Typical uses
- Splitting one high-speed port into four lower-speed links
- Connecting a spine or aggregation port to four servers or switches
- Increasing port density on leaf switches
