Cisco Compatible XFP-10GBX-U-1270 | 10G BiDi XFP 1270/1330nm 20km

Cisco Compatible XFP-10GBX-U-1270 BiDi Optical Transceiver | 10GBASE-BX, 1270nm-TX/1330nm-RX, LC Simplex, SMF (20km)

Product Overview

The Cisco Compatible XFP-10GBX-U-1270 BiDi Optical Transceiver is a high-performance 10Gbps XFP module designed for single-fiber (BiDi) communication over single-mode fiber (SMF). Using Wavelength Division Multiplexing (WDM) technology, it operates with a 1270nm transmitter and 1330nm receiver, enabling bidirectional data transmission over a single fiber strand.

With a transmission distance of up to 20 kilometers, this module is ideal for data centers, enterprise networks, and telecom access networks where fiber resources are limited. Fully compatible with Cisco platforms, it provides a cost-effective and fiber-efficient alternative to traditional dual-fiber transceivers.
