OTDR Testing

OTDR's or Optical Time Domain Reflectometers are a very common piece of test equipment used to troubleshoot fiber optic cables. Recently I viewed a very easy and comprehensive video lecture from the Fiber Optic Assosiation on how to correctly use this piece of test equipment.  This lecture, the first of 3 on OTDRs, covers the basics of how OTDRs work. Click her for the video.
