Axiom Memory AOC-Q-4S-100G-30M-AX 100G QSFP28 to 4 SFP28 Active Optical Cable

Split a single 100GbE QSFP28 port into four SFP28 connections with an integrated active optical breakout assembly. The 30 m reach supports rack-to-rack and row-level links where direct-attach copper is not the appropriate distance option. Each cable provides the fixed QSFP28-to-four-SFP28 fanout needed to map one high-speed uplink or switch port to four downstream 25GbE interfaces. Axiom Memory AOC-Q-4S-100G-30M-AX uses active optical cable construction rather than a collection of separately selected breakout components. The QSFP28 end connects at the 100GbE side, while the four SFP28 ends terminate the individual breakout paths. This configuration is suited to network designs that aggregate four 25GbE host or storage links through a single 100GbE switch interface. The specific distinction of this assembly is its 30 m cable length, active optical construction, and Arista compatibility. It is a fixed-length fanout cable, so endpoint connector types and the required switch-port topology should match the QSFP28-to-four-SFP28 arrangement before installation. Use it where four separate SFP28 connections must remain associated with one QSFP28 100GbE port across the same physical cable route.
