1200487G20 Adtran Compatible 1G SFP BiDi 20km SMF Transceiver

On Adtran access gear the 1200487G20 comes up as a recognized module and needs no host configuration to pass traffic. It is a 1G BiDi SFP working the BX-U (upstream) side of a single-fiber pair, reaching 20km over one strand of single-mode fiber via a simplex LC connector. Because it occupies only the upstream end, it mates with a downstream partner to close the link on a single strand, and it reports its optical health over DDM throughout.
