Arista 400GBASE-VSR4 OSFP Transceiver, MPO-12 APC, OM4 Multimode

Short multimode links in OSFP switches are the job of the Arista OSFP-400G-VSR4. It supports 400GbE over OM4 multimode with an MPO-12 APC connector, and its listed reach is 50 m.

Fifty meters is enough for rack-to-rack and many row-to-row runs. Cage type is the first check, since the module fits OSFP ports only. Tell us how your trunks are terminated and the longest distance in the row, and we will confirm that this module fits your cabling.

The connector is listed as MPO-12 APC, so check that cords and panels match that type. It is a single-port module and works as one half of a link, so order a matching module for the far end. The part is available as a new or refurbished unit, and both list 1 year or 3 years of warranty.
