Cisco Compatible SFP-10GBX-U-1270-40 | 10G BiDi SFP+ 1270nm/1330nm LC SMF 40km

Cisco Compatible SFP-10GBX-U-1270-40 10GBASE BiDi Optical Transceiver (LC Simplex, 1270nm/1330nm, 40km)

Product Overview

The Cisco compatible SFP-10GBX-U-1270-40 BiDi optical transceiver is a high-performance 10Gbps bidirectional module designed for extended-reach single-fiber transmission over single-mode fiber (SMF). Operating at 1270nm transmit / 1330nm receive wavelengths, it supports distances up to 40 kilometers, making it ideal for long-distance enterprise, metro, and telecom applications where fiber efficiency is critical.

This SFP+ BiDi module uses a single LC simplex connector, enabling both transmission and reception over a single fiber strand. It significantly reduces fiber deployment costs while maintaining stable long-distance 10G performance.
