Overview

The 20-790/791 Daisy Chain Switching Module is designed for telecom test applications. It allows production or verification testing of SONET/SDH transmission multiplexers, suitable for rates up to 155MBit/s. Traffic is sequentially Daisy-Chained through all tributaries (or any selection of tributaries), modules can be cascaded to test any number of tributaries. A built in breakout multiplexer allows separate testing of individual ports.

Key Features

  •  Suitable For Testing SONET/SDH Transmission Multiplexers
  •  8 Tributaries Per Module
  •  Up To 64 Tributaries Per Mainframe
  •  Expandable To Any Size: 16, 32, 64, 128, 256...
  •  75Ω Impedance With Choice of Connector Types SMZ/BT Type 43 or 1.0/2.3
  •  All Tributaries Can Be Daisy-Chained to One Signal
  •  Integrated Multiplexer Allows Selection of One Tributary For Analogue Testing
  •  20-791 Version Has Additional Built In Multiplexers For System Expansion
