SFP-10G-BX40U-I — SFP+ 10 Gbps

The SFP-10G-BX40U-I from Cisco is a long-reach BiDi (Bidirectional) SFP+ 10 Gbps transceiver designed for single-strand single-mode fiber (SMF) links. Compliant with the IEEE 10GBASE-BX standard, it reaches 40 km via an LC (UPC) connector, making it the reference module for connecting remote sites over a single optical fiber strand — in upstream transmission, to be paired with the downstream version (BX40D-I).

Ideal for telecom operators, metropolitan networks, and multi-site enterprises looking to maximize their fiber infrastructure utilization by carrying two 10G streams over a single strand. Its industrial temperature range (-40 to 85 °C) makes it suitable for outdoor deployment or unconditioned premises. Genuine Cisco hardware, manufacturer warranty.
