Product Description

The TP-Link SM311L transceiver (TL-SM311LSA-20KM) is an industrial-grade 20KM SFP module designed for reliable long-distance data transmission. This industrial fiber optic module features a single LC duplex interface, supports 1000Mbps full-duplex communication, and operates on a 3.3V voltage range. Built to withstand harsh environments, it functions in temperatures from -40°C to 85°C, making it ideal for power utilities, transportation systems, and factory automation. The module supports up to 20km transmission distance via single-mode fiber (1310nm) and complies with SFP MSA standards for seamless compatibility. Key advantages include high EMI resistance, extended operational lifespan, and stable performance in extreme conditions, though installation requires professional fiber handling expertise.
