1G SFP single-mode fiber transceiver for long-range Gigabit Ethernet links. Supports up to 20 km over SMF at 1310 nm, fully compliant with SFP MSA and SFF-8472.
The DG-1G-LX-SM1310 is a high-performance 1.25 Gbps SFP optical transceiver designed for long-range single-mode fiber connections. Operating at a 1310 nm wavelength using an FP laser transmitter and PIN photodiode receiver, it supports transmission distances of up to 20 km over standard SMF.
The module is compliant with the SFP Multi-Source Agreement (MSA) and SFF-8472, ensuring wide interoperability with enterprise switches, routers, servers, and network interface cards. It supports Digital Diagnostic Monitoring (DDM), enabling real-time monitoring of temperature, supply voltage, bias current, and optical transmit and receive power.
Designed for reliability and continuous operation, the DG-1G-LX-SM1310 is ideal for enterprise networks, campus backbones, data centers, and point-to-point fiber links requiring stable and efficient Gigabit connectivity over extended distances.
