TP-Link 10/100 Mbps WDM Media Converter

Complies with 802.3u 10/100Base-TX, 100Base-FX standards. 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 20km. What This Product Does. TL-FC111B-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. 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 13
