The Arista SFP-50G-MR-SR is a SFP56 50GBASE-SR module from Arista Networks for 50 Gbps links. It plugs into a 50G SFP port on an Arista switch and is used for 50G server and edge connectivity on SFP-based platforms.

Arista specifies the SFP-50G-MR-SR for 100 m on duplex OM4 multimode fiber.

Per Arista's published optics data sheet, the SFP-50G-MR-SR transmits −6.5 to 2.4 dBm and receives −8.4 to 4 dBm.

The SFP-50G-MR-SR uses a Duplex LC connector on multimode (OM4), at 850 nm. Both ends of the link must use the same optical standard.

It works in Arista switches with 50G SFP ports that support this optic. Send us your switch model and EOS version and we will check it against Arista's Transceiver and Cable Guide before dispatch, so you only receive a module that works in your port.

SFP-50G-MR-SR runs on multimode OM4 up to 100 m; SFP-50G-MR-LR runs on single-mode up to 10 km. Both use a duplex LC connector.

Ordering note: Arista lists the 50G SFP optics in its specification and power tables. Confirm current orderability with us before you plan a large deployment.
