Carry 25 GbE traffic between compatible SFP28 ports with a fixed-length active optical cable assembly. ADD-S28ARS28IN-O3M provides a 3 m optical connection for short rack and row-level links where copper cabling is less suitable. Its integrated active optical construction combines the cable and SFP28 transceiver ends into one assembly, so it connects directly to host SFP28 cages rather than requiring separate optical modules and patch cables. The cable has endpoint coding compatible with the Arista AOC-S-S-25G-3M designation on one end and the Intel XXVAOCBL3M designation on the other. This makes it relevant for mixed-vendor links where the connected devices require different vendor-recognized transceiver coding. Both hosts must provide a compatible SFP28 interface and support the required 25 GbE link mode. A 3 m length suits adjacent-rack equipment, top-of-rack switch connections, clustered servers, storage nodes, and high-speed network adapters. As an active optical cable, it is a fixed assembly: the optical ends are attached to the cable and are not intended to be detached or field-terminated. Select it when the endpoint compatibility, 25GBASE-AOC link type, and 3 m reach match the two devices being connected.
