The TP-Link TL-FC111B-20 100 Mb/s WDM Media Converter is a 100M media converter, providing a 100M RJ-45 port and a 100M SC fibre port, which can convert between electrical and optical signals. And long-distance data transmission through optical fibre can be applied to commercial scenarios such as park security monitoring and wireless networking.
TL-FC111B-20 adopts WDM (wavelength division multiplexing) technology, helping send and receive data at a distance of up to 20km (12.4 miles) over only one fiber, which saves half of the cable deployment cost for customers. TL-FC111B-20 transmits data at 1310nm wavelength and receives data at 1550nm wavelength on optical fiber. The TL-FC111A-20 works in the other end as a pair by receiving data at a wavelength 1310nm and sending data at wavelength 1550nm.
