Huawei SFP 1.25G BiDi 1310/1490nm 40km SM Optical Module

The 34060539 SFP-1.25TX1310/RX1490nm-40km-SM-BiDi Optical Module is a high-performance Gigabit Ethernet transceiver designed for long-distance data transmission over single-mode fiber using bidirectional (BiDi) technology. This module operates with a transmit wavelength of 1310 nm and a receive wavelength of 1490 nm, enabling data transmission over a single fiber strand, effectively reducing fiber infrastructure requirements and deployment costs.Supporting data rates of up to 1.25 Gbps, the transceiver is fully compliant with 1000BASE-BX standards and is suitable for metropolitan area networks, enterprise backbone links, campus connectivity, and telecom access networks. With a maximum transmission distance of up to 40 kilometers over single-mode fiber (SMF), it provides stable and reliable long-range optical communication.

Built in a compact hot-swappable SFP form factor, the module allows easy installation and replacement without powering down network equipment. It features an LC simplex connector optimized for single-fiber bidirectional operation. Manufactured according to Multi-Source Agreement (MSA) standards, it ensures interoperability with a wide range of networking equipment, including switches, routers, and media converters.

Designed for low power consumption and high signal integrity, the module delivers consistent performance even in demanding network environments. Digital Diagnostic Monitoring (DDM) support enables real-time monitoring of operational parameters such as temperature, voltage, transmit power, and receive power, improving network stability and simplifying maintenance.
