How to measure optical power after ODF fusion splicing

An Optical Power Meter and Laser Light Source will be used to measure power loss on each completed ring or distribution span to verify continuity between fibers (no fibers incorrectly spliced together). When a fusion splice conducts extremely high optical powers, for ex-ample in the case of an optical fiber laser or amplifier, the optical energy dis-sipated into the fiber's coating can cause localized heating and damage, even including fiber breakage. The splice and the region surrounding should be almost as. OTDR settings are a balance between dynamic range, acquisition time, spatial resolution and accuracy. To minimize testing time, compromises must be made on accuracy (detecting low loss. The document discusses testing the effectiveness of fiber optic splices using optical time domain reflectometry (OTDR) and power meter tests. Connection between the OTDR. In order to measure fiber attenuation, you need a fairly long length of fiber with no distortions on either end from the OTDR resolution or overloading due to large reflections.
