SFP 1.25G 40KM Pair T1310/R1550 LC DDM

The SFP-GE-BX40-A/B 1.25G 40KM BiDi SFP Transceiver Pair is designed for Gigabit Ethernet fibre-optic networking applications that require long-distance data transmission over a single optical fibre.

This matched pair includes two complementary optical transceivers: the A unit, which transmits at 1310nm and receives at 1550nm, and the B unit, which transmits at 1550nm and receives at 1310nm. These complementary wavelengths allow the two units to communicate over one fibre strand when installed at opposite ends of a compatible link.

With a specified transmission distance of up to 40km, these modules are suitable for compatible network infrastructure requiring extended fibre connectivity. The LC optical interface supports fibre connection, while Digital Diagnostic Monitoring (DDM) provides supported optical operating information to help administrators monitor link conditions.

The modules are intended for compatible SFP ports in network switches, routers, media converters and other fibre-optic equipment. Actual compatibility depends on the host device, optical specifications and manufacturer requirements.
