4 Port OC-3/STM-1 LIM Multiplexer (J6828A)

The Viavi Four Port OC-3/STM-1 LIM Multiplexer (J6828A) is designed to be used with the Viavi STM-4/OC-12/STM-1/OC-3 LIM (J6810B) to allow the simultaneous monitoring of both directions of four STM-1/OC-3 circuits.

Обзор

This stand-alone multiplexer has four pairs of STM-1/OC-3 optical input ports. It is designed to be used with the Viavi STM-4/OC-12/STM-1/OC-3 LIM (J6810B) operating in a special mode to expand the latter's analysis capability to both directions of four STM-1/OC-3 ATM cell streams simultaneously. This external LIM is powered from a 5V DC supply with AC input (provided).

Note: This device can only be used with the Viavi STM-4/OC-12/STM-1/OC-3 LIM (J6810B) (is not supported on J6810A, or stand-alone) and is for analysis only - it does not have STM-1/OC-3 optical outputs. Currently this device only provides useful functionality with the Signaling Analyzer Real Time (SART) - Wireless Protocol Test (J7830A) products.

  • Four pairs of SC-PC optical inputs (STM-1/OC-3) for connecting to the network under test
  • One pair of LC-PC optical outputs (STM-4/OC-12) for connecting directly to a J6810B LIM
  • Optical Power measurement on each of the eight input ports
  • Physical Layer line status of each of the eight input ports
