The MC112CS is a media converter designed to convert 100BASE-FX fiber to 100 Base-TX copper media or vice versa. Adopting WDM technology,  MC112CS takes only one fiber cable to transmit & receive data,  which will save half cabling cost for you. Designed under IEEE 802.3u 10/100 Base-TX & 100 Base-FX standards,  the MC112CS is designed for use with single-mode fiber cable utilizing the SC-Type connector. The MC112CS supports longwave (LX) laser 
 Specification at a full wire speed forwarding rate. It works at 1310nm on transferring data & at 1550nm on receiving data. So the other end device to cooperate with the MC112CS should work at 1550nm on transferring data & at 1310nm on receiving data. Another TP-LINKs media converter MC111CS is just one of the examples to cooperate with MC112CS. Other features of this module include the ability to be used as a stand alone device (no chassis required),  Auto MDI/MDI-X for TX port,  Auto negotiation of duplex mode on TX port,  & front panel status LEDs. The MC112CS will transmit at extended fiber optic distances utilizing single-mode fiber up to 20 kilometers.
