SFP-25G-LRLBD-U-I Arista Compatible 25G SFP28 BX-U 10km Transceiver

Deployed on Arista hosts, the SFP-25G-LRLBD-U-I registers as a factory optic and links up with no configuration step. It is a 25G SFP28 BiDi module reaching 10km over a single strand of single-mode fiber as the BX-U upstream end, mating through a simplex LC. Running one fiber for both directions, it earns its place on 25G access and fronthaul links where strand count is the constraint, and the 10km reach covers the distances those single-fiber runs typically span. DDM diagnostics for optical power and temperature are readable at the host as conditions change.
