Description


AN-DS3 modem / converter / extender can be used to provide 44.736M (T3) signal conversion between electrical interface and optical interface of DS3 / TS3 based network interface. It conforms to the ITU- T G.703 T3 recommendation.  The converter features compactness, light weight, low power consumption and high reliability.
The 45M optical / electrical converter operates on 1310 nm lasers, with a typical transmission distance of 40 km over single mode optical fibers. For longer hops, 1550 nm lasers can be selected for 100 km and more distances. WDM single fiber single strand also is available on request.
Exterior power supply, all the functional blocks are integrated on a single PC board, which makes the converter compact and reliable. 220 V AC or – 48 V DC power options are available by selecting an appropriate plug-in power unit.
AN-DS3 electrical interfaces are BNC sockets, “IN” is incoming T3 electrical signal and “OUT” is outgoing T3 electrical signal. The optical interfaces are SC type sockets using receive and transmit integral whole mold piece.
 

Features

  • High reliability, comply to all relevant standards.
  • Single Fiber Bi-Directional is selectable.
  • State-of-the-art design, ensure normal working under different environment.
  • Supports local and remote loop – back on electrical or optical interface for system diagnostic.
  • Suitable for DS3/T3 interface interconnection.
  • Simple operation and maintenance.
  • Compact design and low power consumption.
