TL-FC111PB-20 is 100M media converter providing a 100M RJ-45 port and a 100M SC fiber port,which can convert between electrical and optical signals. Long-distance data transmission through optical fiber can be applied to commercial scenarios such as park security monitoring and wireless networking. 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. TL-FC111PB-20 transmits data at 1550 nm wavelength and receives data at 1310 nm wavelength on optical fiber. Auto-negotiation of half-duplex/full-duplex transfer mode Adopts WDM technology, transmitting and receiving data on one single fiber Extends fiber distance up to 20 km Supports 802.3af PoE output, max 15.4W
