Cisco Compatible XFP-10GBX-U-1270-40 BiDi Optical Transceiver | 10GBASE-BX, 1270nm-TX/1330nm-RX, LC Simplex, SMF (40km)
Product Overview
The Cisco Compatible XFP-10GBX-U-1270-40 BiDi Optical Transceiver is a high-performance 10Gbps XFP module designed for long-distance single-fiber (BiDi) communication over single-mode fiber (SMF). Utilizing advanced Wavelength Division Multiplexing (WDM) technology, it operates with a 1270nm transmitter and 1330nm receiver, enabling bidirectional data transmission over a single fiber strand.
With an extended transmission distance of up to 40 kilometers, this module is ideal for metro networks, telecom access infrastructure, and enterprise backbones where fiber resources are limited but longer reach is required. Fully compatible with Cisco platforms, it offers a reliable and cost-efficient alternative to traditional dual-fiber optics.
