Swapping in the JNP-SFP-25G-BX20U-I is a like-for-like exchange for the Juniper part, keeping the same 25G BiDi profile over a 20km single-mode span. It is an SFP28 that runs 25G on a single strand of single-mode fiber, serving as the BX-U (upstream) unit that terminates one end of a BiDi pair through a simplex LC connector. Seated in a standard SFP28 cage on Juniper hosts, it comes up coded as a native module with no configuration step and reports live optical diagnostics over DDM. Because both directions share one fiber, the 20km reach is achieved without pulling a second strand — preserving the original single-fiber design on the far end.
