Lightwin 1,25 Gbit SFP transceiver, 1310nm, 10km, DDM, LC-duplex, singlemode (LWO-SFP-LX-10)

The Lightwin LWO-SFP-LX-10 stands out in the crowded SFP market by combining a robust FP laser, PIN photodiode, and full DDM functionality in a hot-pluggable package that never compromises on link stability. Engineered for 1000BASE-LX Gigabit Ethernet, this module delivers a 1.25 Gbps data rate over single-mode fibre with a 1310 nm wavelength, reliably covering distances up to 10 km. Its LC-duplex interface ensures a secure, low-loss connection, while the commercial temperature range (0°C to 70°C) makes it suitable for a wide variety of indoor networking environments.

Highlights

• Hot-pluggable SFP form factor for effortless installation and replacement without network downtime.
• Digital Diagnostic Monitoring (DDM/DOM) provides real-time monitoring of temperature, voltage, laser bias, and optical power.
• Low power consumption (<1 W) and 3.3 V operation contribute to energy-efficient network design.
• Full-duplex transmission over single-mode fibre (SMF) with a maximum reach of 10 km.
• Compliant with IEEE 802.3z 1000BASE-LX and RoHS, CE, FCC standards for assured interoperability and safety.

In daily use

Deploy the LWO-SFP-LX-10 in enterprise networks, data centres, or campus backbones where dependable Gigabit Ethernet connectivity is required. Its FP laser and PIN photodiode combination delivers consistent performance across the entire 10 km span, while the LC-duplex connector ensures a firm, low-insertion-loss link. The module's hot-pluggable nature means you can add or replace it in seconds, and DDM support allows network administrators to proactively monitor link health and troubleshoot issues before they escalate. With a mean time between failures (MTBF) designed for long-term reliability, this transceiver reduces maintenance overhead and supports uninterrupted operations.
