Axiom Memory AOC-QSFP-4SFP28-25G-30M-AX 30 m 100GbE QSFP28 to 4 SFP28 Active Optical Cable

Connect a 100GbE QSFP28 host interface to four separate 25GbE SFP28 interfaces through one active optical breakout cable. The Axiom Memory AOC-QSFP-4SFP28-25G-30M-AX provides a 30 m optical link for network designs that need to fan out a high-density QSFP28 port to four 25GbE endpoints. Its active optical construction carries the interface electronics as part of the cable assembly rather than relying on a passive copper path. Use the QSFP28 end at a 100GbE switch, adapter, or other compatible host port, then route the four SFP28 ends to individual 25GbE ports. This topology suits server racks with multiple 25GbE hosts, storage connectivity, and leaf-switch fan-out connections. The 30 m length provides substantially more routing distance than short direct-attach assemblies while retaining a single integrated cable path between the host and branch endpoints. Dell-compatible coding makes this cable appropriate where the connected Dell network equipment requires a compatible optical-cable identity. The specific configuration combines a 100GBASE active optical uplink, four 25GbE SFP28 branches, and a 30 m reach. Confirm that the host side accepts a QSFP28 100GbE breakout connection and that each destination uses a compatible 25GbE SFP28 interface.
