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

The Extreme Networks MGBIC-BX40-D is a bidirectional (BiDi) 1 Gbps SFP transceiver over single-mode fiber (SMF) with a simplex LC connector and a reach of 40 km. Like its U counterpart (MGBIC-BX40-U), it carries a full Gigabit link over a single fiber strand; the D designation (Downstream) identifies its receive direction within the pair, with both modules transmitting and receiving on different wavelengths.

Ideal for network administrators connecting two sites 40 km apart at Gigabit speeds without consuming two SMF fiber strands, the MGBIC-BX40-D installs in the SFP slot of a compatible Extreme Networks switch or router. This type of BiDi link is common in ISP access networks and long-reach campus interconnects. Genuine Extreme Networks hardware, manufacturer warranty.
