SFP-10G-BXU-20KM Cisco Compatible 10G SFP BiDi 20km SMF Transceiver

As the BX-U upstream end of a single-fiber pair, the SFP-10G-BXU-20KM terminates one side of a 10G BiDi link that runs 20km over a lone strand of single-mode fiber. That upstream role and the simplex LC face are its defining traits: matched with its downstream partner, it lets a 10 Gigabit span run on one fiber where a second strand isn't available. It reports DDM diagnostics to the host throughout the link's service life.
