SFP-10G-LR Arista Compatible 10G SFP LR 10km SMF Transceiver

The SFP-10G-LR runs 10G over single-mode fiber to 10km in the SFP form factor, standing in directly for Arista's part of the same coding. Centered at 1310nm and terminated with a duplex LC, it comes up on Arista platforms as a recognized optic — no console work, no adapter mode. DDM/DOM is on board for live monitoring of optical levels once the span is lit.

A 10km budget covers the middle ground of real networks: riser-to-riser links, campus buildings joined over dark pairs, metro access spans that outrun multimode. Built against the relevant MSA and checked one-by-one for diagnostics and link behavior before it leaves the bench. It is backed by TenFourOptics' GreenLights4Life® Limited Lifetime Replacement Warranty. In-stock items ship same or next business day.
