The TP-Link SM311LS MiniGBIC module is a high-performance single-mode SFP transceiver designed for extending fiber link distances in gigabit networks. Supporting 1000Base-LX (1.25 Gbps) transmission, it features an LC/UPC duplex connector compatible with 9/125 µm single-mode fiber. Engineered for seamless integration with many TP-Link switches and media converters, including the JetStream series and MC220L, this hot-swappable module ensures reliable network scalability and flexibility. It supports Digital Diagnostic Monitoring (DDM) for real-time device health monitoring and operates efficiently within a temperature range of 0°C to 70°C. The compact design draws power at 3.3 V from the host device and conforms to SFP MSA standards to maintain broad compatibility. Rated for distances up to 10 km, the SM311LS is ideal for long-distance network deployments requiring stable and fast data transmission. Additionally, it complies with international safety and emission regulations, and ships with an installation guide for straightforward setup.
