Video Description

TDR, OTDR, Multi meter and Environmental Monitor This lesson covers the following tools:

  • Time domain reflectometer (TDR): device which sends signals and listens to reflections back. TDRs estimate cable length; find cable faults and splices.
  • Optical time domain reflectometer (OTDR): used for fiber
  • Multimeter: measures electricity for resistance, current, voltage and continuity.
  • Environmental monitor: monitors the environment for humidity, temperature and air particles
