TP-Link Gigabit Single-Mode Media Converter MC210CS Highlights: Complies with IEEE 802.3ab and IEEE 802.3z Provides switch configuration of Force /Auto transfer mode for FX port Extends fibre distance up to 15km Warranty 3-years Media converter designed to convert 1000BASE-LX/LH fibre to 1000Base-T copper media or vice versa. Designed under IEEE802.3ab 1000Base-T and IEEE802.3z 1000Base-LX/LH standards, the MC210CS is designed for use with single-mode fibre 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 TP-LINK´s 19´´system chassis,Auto MDI/MDI-X for TX port, and front panel status LEDs. The MC210CS will transmit at extended fibre optic distances utilizing single-mode fibre up to 15 kilometers.
