Provides step-by-step instruction on how to complete each fiber optic task. Enhanced with high quality graphics. Does the following terminology and theory confuse you when operating an OTDR? Index of refraction (IR), averaging, fresnel and rayleigh backscatter, pulse width, 2 point and auto (LSA) loss measurements. If so, this CD would be helpful. The OTDR is one of the most widely used yet least understood instruments in fiber optics. Takes you through a step-by-step explanation that demonstrates how the OTDR works and its role in fiber optic measurements. Learn how to use the OTDR for acceptance testing, splice monitoring, and emergency restoration applications. Covers: characteristics of an OTDR, signatures, and using the OTDR.
