Media Converter, Fast Ethernet, 1000Base-FX Multimode 550M to Single Mode 20K, Duplex SC

100M adaptive fast Ethernet optical media converter is used for optical transmission via high-speed Ethernet. It is capable of switching from optical Multimode to optical single mode and relaying across 1000 Base-FX network segments, meeting long-distance, high-speed and high-broadband fast Ethernet workgroup users' needs, achieving high-speed remote interconnection for up to 550M for multimode and 20km on single mode relay-free computer data network.

With steady and reliable performance, design in accordance with Ethernet standard and lightning protection, it is particularly applicable to a wide range of fields requiring a variety of broadband data network and high-reliability data transmission or dedicated IP data transfer network, such as telecommunication, cable television, railway, military, finance and securities, customs, civil aviation, shipping, power, water conservancy and oilfield etc, and is an ideal type of facility to build broadband campus network, cable TV and intelligent broadband FTTB/FTTH networks.

The MC-4966/20K/MM/SM is an auto-adaptation unmanaged media converter that provides an interface between 1000BASE-FX Duplex SC Multimode Ports to 100BASE-FX Duplex SC SingleMode ports, allowing users to integrate fiber optic cabling from MultiMode to Signle-Mode environments or vis versa. This Media Converter is in accordance with Ethernet standard IEEE802.3, 1000BASE-FX.
