OverviewReliability and quality of OTDR equipmentTypes of OTDR-like test equipmentOTDR data format
The reliability and quality of an OTDR is based on its accuracy, measurement range, ability to resolve and measure closely spaced events, measurement speed, and ability to perform satisfactorily under various environmental extremes and after various types of physical abuse. The instrument is also judged on the basis of its cost, features provided, size, weight, and ease of use. Some of the terms often used in specifying the quality of an OTDR are as follows:
