Abstract

The Optical Time Domain Reflectometer (OTDR) has been used to measure splice loss in fiber optic cables for several years. The OTDR requires bidirectional measurements be made and values averaged to get an accurate result. One theory implies that knowing optical characteristics of the fibers being spliced could allow for a measurement to be made in one direction only. This paper investigates that theory, and our findings indicate that bidirectional measurements are required in order to achieve accurate results.
