Overview

1.25G BiDi (Bidirectional) SFP optical transceiver is a high-performance, compact solution designed for single-fiber bidirectional communication in Gigabit Ethernet and Fiber Channel applications. Operating at 1.25Gbps, it transmits data at 1550nm wavelength and receives at 1310nm over a single strand of single-mode fiber (SMF), enabling efficient fiber utilization and cost savings. With a transmission distance of up to 20 kilometers, this LC-interface module is ideal for metro access, enterprise networks, and telecom infrastructure.

Compliant with SFP MSA and IEEE 802.3 standards, it ensures seamless compatibility with industry-standard networking equipment. The transceiver features low power consumption, industrial temperature range support (-40°C to 85°C), and digital diagnostics monitoring (DDM/DOM) for real-time performance tracking. Its hot-swappable design allows easy installation and maintenance, making it a reliable choice for high-density deployments. Built for durability and stability, this BiDi SFP module delivers an optimal balance of performance, flexibility, and cost-effectiveness in modern optical networks.
