The MC220L is a media converter, which is designed to, 1000BASE-SX/LX/LH fiber media in 1000Base-T-copper media or vice versa to convert. The MC220L has been developed according to the IEEE 802.3ab 1000Base-T standard and the IEEE 802.3z 1000Base-SX/LX/LH standard designed for use with multi-mode/single mode glass fiber cable and the SC/LC-plug. It works at 850 nm both sending and receiving of data when it is multi-mode fiber used and 1310 nm both sending and receiving of data, if he is a single-mode fiber-optic cable is used. Further properties of the module are: the possibility of the device as an independent device (there is no housing required) or with the 19-inch system housing from TP-LINK to use auto-MDI/MDIX for the transmission port and status LED on the front side. The MC220L sends in the fiber-optic long distance mode with the help of the multi-mode fiber cable up to a distance of 550 m and using a single-mode fiber cable up to a distance of 10 km away.
