The technology enables technicians to accurately detect, locate, and measure various fiber characteristics including attenuation, splice losses, connector losses, and break points along the entire length of the fiber cable. Splicing is required to create a continuous path for light transmission from one fiber to another. Two different methods exist for splicing fibers: Typical splice loss values (the measure of loss in optical power across the splice point) are usually lower for fusion splices (typically less than 0. 1. To be able to judge whether a fiber optic cable plant is good, one does a insertion loss test with a light source and power meter and compares that to an estimate of what is a reasonable loss for that cable plant. Demountable connections retain alignment mechanically while permanent connections retain alignment through melting and. Example: Point Sensor with 30 meters Black-Jacketed fiber length. Range for 'A' equals 1-30 meters. Intrinsic factors, such as the refractive index of the fiber, are those that are inherent to the fiber itself.
