E1/T1 Fiber Modems

The EM316T1 and the EM316E1 modules of the Fiber Driver^® family are designed to extend the distance and transmission reliability of T1 (1.544Mbps) or E1 (2.048Mbps) traffic. These units convert the electrical signals to optical signals and transmit them over distances of up to 10 km on Multimode fiber, or distances of up to 100 km on Singlemode fiber. The EM316T1 and EM316E1 are transparent to the framing format, and support AMI or B8ZS (T1) and HDB3 (E1) line codes, respectively. They include an internal elastic buffer to remove jitter from the transmitted data. Six LED indicators aid in monitoring and trouble-shooting this module. A management agent is incorporated on the module to enable management in conjunction with the Fiber Driver EM316NM management card. As part of the Fiber Driver family, the EM316T1 and EM316E1 modules fit in all Fiber Driver chassis types, support local and remote loopback tests, and can be used to interconnect between any T1 or E1 devices. Among the types of T1/E1 devices that can be connected by these modules are PBXs, multiplexers, video CODECS, routers, network servers, and ATM/frame relay switches. Benefits include extended distances, improved quality of transmission, better security, remote management capability, and high density.
