QSFP-4SFP25G-CU1M=

The QSFP-4SFP25G-CU1M is a passive breakout copper cable, 1 m long. One end is a 100G QSFP28 connector, and the other splits into four SFP28 connectors, each carrying one 25 Gigabit Ethernet lane. The switch port must be set to split into four 25G interfaces, and FEC settings should match on all four far-end ports. It lets a single 100G switch port serve four 25G servers or NICs, reducing the leaf ports needed per rack. Route it clear of power cords and fan exhaust where possible, to keep the cable run tidy and serviceable. Plan the route before ordering, because a fixed-length cable cannot be shortened or extended later. Laying the cable in before the equipment is fully racked leaves the final connection for last and saves rework. At this length it suits tight in-rack links where a longer cable would only leave a bundle of slack behind the doors. The cable is a single sealed assembly, supplied as the spare part number with the equals suffix.
