Abstract

A compact optical time domain reflectometer (OTDR) containing a small-scale OTDR, power source, and wireless communications electronics encompassed within the confines of a spool containing a time delay fiber optic waveguide coiled about the face of the spool. Data obtained by the OTDR is transmitted by wire or wirelessly to a computer or portable wireless device for graphical plotting of said data and evaluation by the user. The integration of the time delay waveguide eliminates the need for a separate time delay waveguide and provides a more compact testing solution. The Compact OTDR with Integrated Time Delay is used to test the integrity of an optical fiber waveguide.
