SFP Optical Transceiver Module

This 1.25G SFP optical transceiver module is a hot-pluggable Gigabit optical module designed for high-speed fiber optic data transmission. It is widely used in Gigabit Ethernet switches, routers, firewalls, network security equipment, OLT terminals and fiber optic transmission systems in data centers, telecom rooms, campus networks and security monitoring projects.

Compliant with IEEE 802.3 Gigabit Ethernet and SFP MSA standards, it adopts 1310nm FP laser and PIN photodetector, supporting full-duplex 1.25Gbps transmission over single-mode dual fiber with a maximum distance of 10km. The built-in DDM (Digital Diagnostic Monitoring) function allows real-time monitoring of temperature, supply voltage, laser bias current, transmit optical power and receive optical power via the switch management system, facilitating network operation and maintenance.

The standard LC duplex optical interface matches all conventional LC fiber patch cords. It is widely compatible with mainstream brand equipment including Cisco, Huawei, H3C, Juniper, Arista, Dell, MikroTik and other open-standard switches and network devices, supporting plug-and-play without additional configuration.

Various distance grades (10km, 20km, 40km, 80km) and single-fiber BiDi versions are available. We also provide 10G SFP+, 25G SFP28 and other rate modules. Custom brand coding, private labeling and bulk packaging services are supported for distributors and system integrators.
