Product Description

The TL-SM311LSB SFP module is a 20KM Industrial SFP Transceiver designed for high-speed data transmission over single-mode fiber optic networks. Supporting Gigabit Ethernet and Fiber Channel standards, this SM311LSB-20KM Fiber Optic module operates at 1310nm wavelength and features an LC duplex interface. It operates within a wide industrial temperature range of -40°C to 85°C and a voltage range of 3.3V±5%, ensuring reliability in harsh environments like industrial automation, smart transportation, and energy systems. With a 20km transmission distance, it enables long-range connectivity for switches, routers, and media converters. Key advantages include robust EMI resistance, low power consumption, and hot-swappable compatibility. As a dedicated transceiver, it lacks a built-in battery, screen, or sensor-based detection features, focusing solely on high-performance optical communication.
