Note: The TP-Link TL-FC311B-2 is a Gigabit WDM Media Converter designed to convert 10/100/1000Mbps Ethernet signals to 1000Mbps fiber transmission. It features 1 × Gigabit RJ45 Ethernet port and 1 × SC fiber port for Single-Mode fiber. Using WDM Bi-Directional technology, it transmits and receives data over a single fiber strand at different wavelengths, with a transmission distance of up to 2km. The TL-FC311B-2 operates at 1310nm TX and 1550nm RX.
Important: The TL-FC311B-2 is a Gigabit WDM Media Converter featuring 1 × 10/100/1000Mbps RJ45 Ethernet port and 1 × SC Single-Mode fiber port. It uses WDM Bi-Directional technology to transmit data over a single fiber strand, supporting transmission distances of up to 2km. The TL-FC311B-2 operates at 1310nm TX / 1550nm RX and must be paired with the corresponding WDM converter using the opposite wavelength.
