8E1 to Optical Ethernet Converter

Functions

8E1 to optical ethernet (100Base-FX) converter use back multiplexing technology, transfer 10M/100M Ethernet data by using multi E1 channels. Realize convert between 1 to 8 E1 channels and Ethernet interface. It can transmit signal of E1 channel to RJ45 interface point to point, realize the connection of E1 channel and Ethernet. It different from normal bridge , supporting 1 to 8 E1 channels customized configuration, auto detecting the number of E1 channels and use the available E1, allow some limiting transfer delay between different E1 channels. Single line speed is 1968Kbits/s, 8 channels can up to 15744Kbits/s. it can connect with Ethernet switch or hub when in 10/100Mbps full/half duplex mode, make use of mass E1 resource in telecommunication networks to expend the transfer distance and application field of Ethernet, is a suitable solution for broadband switch in of Ethernet. It can used in fields such as connecting LANs, connecting end offices, VOD, remote monitor, E1 interface of switches, etc.
