OTDR measurements are particularly helpful for identifying problems. For example, if the bit error rate of a fiber-optic link is too high, that can have many causes.
The event dead zone is the minimum distance after a reflection event for which the reflectometer can accurately evaluate the individual characteristics of two consecutive reflection events.
An OTDR has complex specifications, and most of them entail trade-offs. A solid understanding of these parameters and how to verify them will help buyers make the right choice for their
