10/100Mbps fast Ethernet Converter. It provides two 10/100M ports switch auto-MDI/MDIX and one 100M fiber port which can extend the network radii. It complies with IEEE802.3 and IEEE 802.3u Standards. It enables network managers to connect 10 Mbps and 100 Mbps twisted pair network segments and active equipment to fiber optic cabling more cost-effectively than ever. WDM Technology Combines Dual Fiber Cables into Single Fiber .Greatly save the Installation cost of Expensive Fiber Cable.  Both a media and data rate converter, it ?features 10/100 auto-negotiation on the twisted pair port while the fiber port operates at 100 Mbps. It series converters are
ideal for any premises FTTD, LAN-to-LAN or LAN-to-WAN fiber networking applications.
