What This Product Does
FC111A-20 (TL-FC111A-20) is a 100M media converter, providing a 100M RJ-45 port and a 100M 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
FC111A-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. FC111A-20 transmits data at 1550nm wavelength and receives data at 1310nm wavelength on optical fiber. Therefore, the terminal device used in conjunction with the FC111A-20 should send data at a wavelength of 1310nm and receive data at a wavelength of 1550nm. TP-Link another media converter FC111B-20 is one of the products that can cooperate with FC111A-20.

Other Features
Besides, this media converter can be used as a standalone device (no rack required) or used with TP-Link’s FC1420 rack for auto MDI/MDI-X in TX port in which duplex mode is automatically negotiated.
