WDM Fast Ethernet Media Converter MC111CS The MC111CS is a media converter designed to convert 100BASE-FX fiber to 100Base-TX copper media or vice versa. Adopting WDM technology, MC111CS takes only one fiber cable to transmit and receive data, which will save half cabling cost for you. Designed under IEEE 802.3u 10/100Base-TX and 100Base-FX standards, the MC111CS is designed for use with single-mode fiber cable utilizing the SC-Type connector. The MC111CS supports shortwave (SX) laser specification at a full wire speed forwarding rate. It works at 1550nm on transferring data and at 1310nm on receiving data. So the other end device to cooperate with the MC111CS should work at 1310nm on transferring data and at 1550nm on receiving data. Another TP-LINK’s media converter MC112CS is just one of the examples to cooperate with MC111CS. Other features of this module include the ability to be used as a stand alone device (no chassis required) or with TP-LINK’s 19’’ system chassis, Auto MDI/MDI-X for TX port, Auto negotiation of duplex mode on TX port, and front panel status LEDs. The MC111CS will transmit at extended fiber optic distances utilizing single-mode fiber up to 20 kilometers. Features: Auto negotiation of 10/100Mbps and auto MID/MID-X for TX port Provide switch configuration of Half-Duplex / Full-Duplex transfer mode for FX port Adopts WDM technology, transmitting and receiving data on one single fiber Extend fiber distance up to 20-60km Easy-to-view LED indicators provide status to monitor network activity easily External power supply Specifications: Standards and Protocols IEEE 802.3, IEEE 802.3u, IEEE 802.3x Basic Function Adopts WDM technology Half/Full-Duplex transfer mode for FX port Full Duplex Flow Control (IEEE 802.3x) Half Duplex Flow Control (Backpressure) Extends fiber distance up to 20km Ports 1 100M SC port 1 100M RJ45 port (Auto MDI/MDIX) WDM TX 1550nm RX 1310nm Network Media 10BASE-T UTP category 3, 4, 5 cable (maximum 100m) EIA/TIA-568 100Ω STP (maximum 100m) 1000BASE-T UTP category 5, 5e cable (maximum 100m) EIA/TIA-568 100Ω STP (maximum 100m) 1000BASE-FX Single-mod Fiber LED Indicators PWR, FDX/Col, Link/Act, SPD Safety & Emission FCC, CE Dimensions (W*D*H) 3.7*2.9*1.1 in.
