10GB-BX40-U — Module SFP+ 10 Gbps Extreme Networks — 10 Gb Bidirectional 40 km SFP+ Module

The 10GB-BX40-U module from Extreme Networks is a bidirectional (BiDi) SFP+ 10 Gbps transceiver for single-mode fiber (SMF), with a reach of 40 kilometers and an LC simplex connector. Bidirectional transmission over a single fiber strand (upstream direction) cuts the number of fibers required for long-haul links in half.

This module is designed for operators and CIOs who need to extend their network over 40 km while conserving fiber infrastructure — for example, linking remote sites in pairs with the complementary 10GB-BX40-D module. Its LC simplex connector simplifies patching on existing ODFs. Genuine Extreme Networks hardware, manufacturer warranty.
