SFP-GD-BD53 MRV Compatible 1G SFP BiDi 40km SMF Transceiver

Read from the part code, the SFP-GD-BD53 is a 1G BiDi SFP working a single strand of single-mode fiber to 40km through a simplex-LC connector — the MRV-coded version of exactly that single-fiber optic. As the BX-D (downstream) unit it terminates the downstream end of a BiDi pair, the module you fit on access spans where a second strand isn't available.
