  2. E2 , 2Mbps x 4 - Opti Multiplexer Product Overview • VCL-E2, Opti Multiplexer (4E1) is an Integrated OLTE and multiplexer/ demultiplexer unit, basedon PDH (Plesiochronous Digital Hierarchy) technology • It multiplexes four 2.048Mbps (hereafter referred to 2Mbps) E1 tributaries into a single 8Mbps, E2 stream and then transports it as an optical signal on a Single Mode, 1300nm optical fiber cable, without the use of ant signal repeaters up to a distance of over 50KM (optical loss budget 30dBm) • On the demultiplex side, it receives the optical signal and demultiplexes it into 4, electrical E1 signals • This device provides data and extracted jitter free clock meeting the G.703 standards • These include loss of signal at E1, loss of signal at E2, loss of frame sync at E2, detection of AIS at E2 and bit error exceeding 1 in 1000 • VCL-E2, Opti Multiplexer is available in • 1310nm • 1550nm.

  3. E2 , 2Mbps x 4 - Opti Multiplexer Features • A compact solution that performs E1 to E2 multiplexing • and de-multiplexing and provides an 8Mbps • Optical interface (8Mbps OLTE) in a single card • Conforms to ITU recommendations G.742 • Performs Second order Mux as per G.742 • Loss of signal and AIS detection as per G.775 • Tributary and higher order loop backs supported • Supports tributary loopbacks for commands received from far end based on • stuff bit polarity • Single-card implementation • Highly reliable and compact • Standard CCITT Interfaces • Class I Laser

  4. E2 , 2Mbps x 4 - Opti Multiplexer Highlights • Remote and local terminal monitoring and control through a PC Com port using • VCL-Opti Multiplexer, Network Management System • Extensive alarms and status indication facility • Operates on nominal -48V DC input • Distributed on-board power supply • Microprocessor controlled with powerful diagnostic facilities for both remote and local systems • Local and remote loopback facility for the 8Mbps stream for diagnostics • Programmable auto-laser shut down feature for greater safety • Capable of synchronizing on any of the clock sources - internal, or • extracted (loop-timed).
