FC111PB-20

FC111PB-20 (TL-FC111PB-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. FC111PB-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 FC111PB-20 should send data at a wavelength of 1550 nm and receive data at a wavelength of 1310 nm. TP-Link another media converter FC111A-20 (TL-FC111A-20) is one of the products that can cooperate with FC111PB-20. 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.
