Lightwin LWO-SFP100-SX 155 Mbps SFP-transceiver, 2 km, LC duplex, multimode, DDM

Network administrators upgrading legacy Fast Ethernet links in campus or enterprise environments can rely on the Lightwin LWO-SFP100-SX to deliver stable 155 Mbps connectivity over multimode fiber up to 2 km. This hot-pluggable SFP module fits standard SFP ports and uses a 1310 nm FP laser with an LC duplex connector, making it a direct replacement for existing multimode fiber transceivers. Digital Diagnostic Monitoring (DDM) provides real-time monitoring of key parameters such as optical power, temperature, and voltage, simplifying troubleshooting and proactive maintenance.
