PFW-1G-BX40U PacketFront Compatible 1G SFP BiDi 40km SMF Transceiver

Decoded from its label, the PFW-1G-BX40U is a 1G BiDi SFP reaching 40km over a single strand of single-mode fiber through a simplex-LC connector — the PacketFront-coded version of exactly that single-fiber optic. Running both directions on one strand, it is what you fit where pulling a second fiber isn't practical, on subscriber and access spans out to the full 40km.
