On Nokia platforms calling for the SFP-GIG-BX-U-120, this SFP is the compatible upstream match: a 1G BiDi module carrying a single gigabit over one strand of single-mode fiber all the way to 120km. As the BX-U unit it terminates the upstream end of a BiDi pair through a simplex LC, paired with a downstream module at the opposite end of the long haul, which is how a full gigabit spans that distance on a single strand. It reads to the host as the original part, so the port comes up with no configuration required and the 120km link plan carries over as designed.
