 OMT240D Optical-Electronic Multiplexer

  The multiplexer with new PDH technology and design meets the latest national and international technology standard. Terminal multiplexing mode, multiplexing mode and delay transmission mode, double-fiber self-healing ring can be formed.


  Multiplexing 16 E1 tributary signals at most, the capacity equaling to a tertiary group

  E1-10Base_T interface converter and E1-V.35 interface converter can be set in the equipment. Flexible configuration, add/drop of multiple tributaries at any station in the net, easy to reconfigure.

  Either -48V DC or 220V AC can be selected as the power supply.

       

  Network supervision DB9, adopt RS232 to connect to the PC. Engineering orderwire RJJ11, and the Ethernet indicator is beside  it.


     
  4 DB15 connectors are 16 E1 interfaces, either balance, or unbalance. There is a cable between the DB15 and the coaxial.


            

 2 RJ45 interfaces on the back panel can transmit 2 channels 10/100Base_T Ethernet signal.

　

 　
　 　 　 　 　 　 　 　 　 　 　 　 　
　

























OMT240
Operating Modes

 　 　
  •  point-to-point mode and add/drop mode

  • single-fiber mode to achieve add/drop of multiple tributaries at any station in the net.
  • Double-fiber self-healing ring.

Self-healing
ring









 The communication mode is familiar to the bypass drop in the double-fiber self-healing ring and the reliably of the system is enforced. To choose loop or link is determined by fiber laying router and geographical distribution of the stations.
