How This Product Works

TL-FC111B-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-FC111B-20 transmits data at 1310nm wavelength and receives data at 1550nm wavelength on optical fiber. Therefore, the terminal device used in conjunction with the TL-FC111B-20 should send data at a wavelength of 1550nm and receive data at a wavelength of 1310nm. TP-Link another media converter TL-FC111A-20 is one of the products that can cooperate with TL-FC111B-20.
