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

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

Product Overview

The Cisco compatible SFP-10GBX-U-1270 BiDi optical transceiver is a high-performance 10Gbps bidirectional (BiDi) module designed for efficient single-fiber transmission over single-mode fiber (SMF). Operating at 1270nm transmit / 1330nm receive wavelengths, it supports distances up to 10 kilometers, making it an excellent choice for fiber-constrained environments.

This SFP+ BiDi module uses a single LC simplex connector, allowing both transmission and reception over one fiber strand. It significantly reduces fiber infrastructure costs while maintaining full 10G performance and reliability.
