 The Fiber DriverT T1 Fiber Multiplexer from MRV Communications transmits 
            four T1 data channels across a fiber optic trunk in a Point-to-Point 
            (PtP) configuration. Each line interface consists of a B8ZS, or AMI 
            encoder/decoder as applicable, 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 100 
            m are supported. Line protection is designed to meet Telecordia GR-1089.
 
 The fiber trunk can be either Singlemode or Multimode, dual or single 
            fiber, using LC, SC, or DSC connectors. The T1 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 T1 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.
