TP-Link Gigabit WDM Media Converter

What This Product Does|FC311B-20 (TL-FC311B-20) is a gigabit media converter, providing a gigabit RJ-45 port and a gigabit SC fiber port, which can convert between electrical and optical signals. And long-distance data transmission through optical fiber can be applied to commercial scenarios such as park security monitoring and wireless networking.How This Product Works|FC311B-20 (TL-FC311B-20) adopts WDM (wavelength division multiplexing) technology, helping send and receive data at a distance of up to 20 km with only a single mode fiber, which saves half of the cable deployment cost for customers. TL-FC311B-20 transmits data at 1310 nm wavelength and receives data at 1550 nm wavelength on optical fiber. Therefore, the terminal device used in conjunction with the FC311B-20 (TL-FC311B-20) should send data at a wavelength of 1550 nm and receive data at a wavelength of 1310 nm. TP-Link another media converter FC311A-20 is one of the products that can cooperate with FC311B-20.
