Ever wondered why your OTDR isn’t reliably accurate in detecting all the events on your fiber under test? One reason is that there isn’t just one test configuration that is optimal to characterize a link with a single OTDR shot. If you use an OTDR test pulse that’s too short, you’ll miss seeing events towards the far end of the fiber. If you use the OTDR long pulse, you will see the those far-end events clearly, but might end up missing the splice-point events closer to the near end.
Are you being “smart” about OTDR Testing?
