 The Fiber DriverT E1 Fiber Multiplexer from MRV 
Communications transmits four E1 data channels across a fiber optic trunk in a 
Point-to-Point (PtP) configuration. Each line interface consists of a HDB3 
encoder/decoder, and a receiver with equalizer for reliable data and clock 
recovery. The device also includes a crystal-less jitter attenuator which, 
depending on system requirements, can be set in the transmit (TX) or receive 
(RX) path. Line distances from 0 to 100m are supported. Line protection is 
designed to meet Telecordia GR-1089 standards. The Fiber Driver E1 Fiber Mux is 
G.703 interface and G.704 framing compliant.
 
 The fiber trunk can be 
either Singlemode or Multimode, dual or single fiber, using LC, SC, or DSC 
connectors. The E1 Fiber Mux can also be configured with the Multimode Extender 
(MMX) transceiver. With MMX technology - available exclusively from MRV 
Communications in the Fiber Driver product line - a link of up to 6 km can be 
achieved over a Multimode fiber trunk.
 
 The E1 Fiber Mux offers extensive 
management functions. Diagnostic LED indicators ease installation and 
troubleshooting. When paired with the Fiber Driver Network Management Module 
(EM316NM), system activities such as loss of signal, transmit and receive signal 
detection, system temperature, power supply status, and more can be monitored 
remotely via SNMP using MegaVision Web, MRV Communications own Network 
Management System (NMS), or any other standard NMS. On-card jumpers allow for 
manual configuration of local and remote loopback, jitter attenuation, and other 
settings.
