Omada Gigabit Single-Mode Media Converter MC210CS 1× 10/100/1000Mbps Auto-Negotiation RJ45 port supporting Auto-MDI/MDIX Auto-negotiation of Half-Duplex / Full-Duplex transfer mode Complies with IEEE 802.3ab and IEEE 802.3z Extends fiber distance up to 20km What This Product Does The MC210CS is a media converter designed to convert 1000BASE-LX fiber to 1000Base-T copper media or vice versa. Designed under IEEE802.3ab 1000Base-T and IEEE802.3z 1000Base-LX standards, the MC210CS is designed for use with single-mode fiber cable utilizing the SC-Type connector. The MC210CS supports longwave (LX) laser specification at a full wire speed forwarding rate. It works at 1310nm on both transmitting and receiving data. Other features of this module include the ability to be used as a stand alone device (no chassis required) or with MC1400 chassis, Auto MDI/MDI-X for TX port, and front panel status LEDs. The MC210CS will transmit at extended fiber optic distances utilizing single-mode fiber up to 20 kilometers.
