MGBIC-BX40-U — Module SFP 1 Gbps Extreme Networks — 1000BX Bidirectional 40 km SFP Module

The Extreme Networks MGBIC-BX40-U is a bidirectional (BiDi) 1 Gbps SFP transceiver over single-mode fiber (SMF) with a simplex LC connector, offering a reach of 40 km. The U suffix (Upstream) indicates its upstream transmit role within the BiDi pair; it must be paired with the MGBIC-BX40-D at the far end to form a complete link over a single fiber strand.

This part number suits access providers, local authorities, or multi-site enterprises needing to interconnect nodes up to 40 km apart over a single strand of single-mode fiber, optimizing their optical infrastructure. Its intermediate reach — between the 10 km and 120 km variants — addresses common metropolitan connectivity requirements. Genuine Extreme Networks hardware, manufacturer warranty.
