JNP-SFP-10G-BX40D Juniper Compatible 10G SFP BiDi 40km SMF Transceiver

As the BX-D (downstream) end of a single-fiber BiDi pair, the JNP-SFP-10G-BX40D terminates one side of a 10G link over a single strand of single-mode fiber, reaching up to 40km through a simplex LC connector. It seats in a standard SFP+ cage and comes up on Juniper platforms with no configuration required, streaming optical diagnostics over DDM so the 40km span can be watched from the host.
