Cisco 25GBASE-AOC SFP28 Active Optical Cable, 3 m

A fixed-length optical link for 25GbE ports is what the Cisco 25GBASE-AOC SFP28 Active Optical Cable, part number SFP-25G-AOC3M, provides. The optics are integrated into the SFP28 connectors on each end, so the cable arrives as one assembly 3 m long with nothing to snap in separately.

Active optical construction makes the cable thinner and lighter than copper of the same speed. In a rack crowded with server connections, that makes routing and airflow easier. At 3 m, it suits server-to-switch links within a rack or to an adjacent one.

Because the length is fixed and the optics are built in, check your route carefully. A short cable cannot be extended, and a failed cable is replaced as a whole unit rather than by swapping a module.

Each end plugs into an SFP28 port, so both the server adapter and the switch need SFP28 cages that accept this cable. Platforms vary in which active cables they allow, so verify host support.

The SFP-25G-AOC3M is offered new, refurbished and used. New and refurbished cables carry 1 year or 3 years of warranty, and used cables carry 90 days. Send your quantity and host platforms when requesting pricing.
