The loss of the pigtail splice and connector will be measured and recorded at 1550nm. The loss value of a pigtail connector and its associated splice with matching mode field diameters should not. If the pigtail is sufficiently long, 10 meters or so, VIAVI SolutionsTM Optical Time Domain Reflectometers (OTDRs) with pulses as short as 1 foot can perform these measurements. The OTDR is also commonly used to create a "picture" of fiber optic cable when it is newly installed. It is recommended for fiber testing per industry standards, essential for emerging short-reach single-mode. OTDR settings are a balance between dynamic range, acquisition time, spatial resolution and accuracy. 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. Part one consists of OTDR trace data in the form of pigtail and bi-directional span shots.
