BTI-SFP-GBD40E-DD-49/31S Telco Systems Compatible 1G SFP Transceiver

On Telco Systems platforms, the BTI-SFP-GBD40E-DD-49/31S comes up as a native single-fiber module and needs no configuration to bring the port online. It is a 1G BiDi SFP reaching 40km over one strand of single-mode fiber, and as the BX-D (downstream) unit it terminates one end of a BiDi pair through a simplex LC connector. Optical diagnostics stream over DDM for host-side monitoring across the 40km span.
