The MC110CS is a media converter designed to convert 100BASE-FX fibre media to 100Base-TX copper media or vice versa. The MC110CS is designed in accordance with the IEEE802.3u(10/100Base-TX) standard and the (100Base-FX) standard, and is intended for use with single-mode fibre cables with SC connectors. The MC110CS supports the long-wavelength (LX) laser specification at a forwarding rate equivalent to full... bandwidth. It transmits and receives at a wavelength of 1310nm. Other features of the module include: the ability to be used as a stand- alone unit (no additional enclosure required) or with TP-LINK's 19-inch system enclosure, auto-MDI/MDIX for the transmit port, duplex mode auto- tuning on the transmit port and front panel status LED. The MC110CS transmits in Fibre Optic Long Distance mode using single-mode fibre optic cable up to a distance of 20km.
