Axiom Memory AOC-Q-4S-100G-25M-AX 100G QSFP28 to 4 SFP28 Active Optical Cable

Break out a single 100GBASE QSFP28 connection into four SFP28 optical connections over a 25 m fixed-length cable assembly. AOC-Q-4S-100G-25M-AX provides a QSFP28 end for the 100 Gigabit host interface and four SFP28 ends for 25 Gigabit downstream links. The active optical construction combines transceivers and fiber into one captive assembly, removing the need to select separate optics and fiber jumpers for this specific breakout path. Use this cable where a 100G switch port must fan out to four 25G server, storage, or network interfaces. It fits rack rows and adjacent cabinets where 25 m provides reach beyond short in-rack copper breakout cables while retaining a direct port-to-port assembly. The four SFP28 legs let an engineer allocate one QSFP28 port to four independent 25G physical connections, subject to host-port breakout support and switch configuration. This specific cable is built for an Arista-compatible interface environment and uses a 100GBASE optical breakout format rather than a passive copper assembly. Its 25 m length is a defining selection point: verify the cable route and available QSFP28 and SFP28 port types before installation. The fixed cable ends are intended for direct connection between the supported host interfaces; no field-replaceable transceiver modules are required at either end.
