Methods and Apparatus for Measuring Insertion Loss in a Fiber Optic Cable Connection

摘要

A method and apparatus for measuring the insertion loss of a fiber optic connection is provided. The invention generally comprises a light source providing light to a test connector which contains a juncture of two fiber optic cables. The test connector has one or more opaque portions surrounding the fiber optic juncture. A pyrometer or other heat detection means is then used to measure any temperature increase as a result of light scattered into the opaque portions of the test connector.
