(OTDR) Introduction In fiber optic networks‚ OTDR (Optical Time Domain Reflectometer) is an opto-electronic instrument used to characterize an optical fiber. Unlike power meters OTDR does not measure loss‚ but instead implies it by looking at the backscatter signature of the fiber. Generally‚ OTDR are used to determine the loss of any part of a system‚ the length of the fiber and the distance between any points of interest. Most of the light which is sent to the fiber can be detected at the other

structural integrity of components in service. Techniques for embedding fiber optic sensors in metals‚ polymers‚ and ceramics have been investigated. Embedding optical fibers into metals is especially challenging because engineering alloys tend to exhibit high melting temperatures. In the present research an embedding sequence was developed capable of embedding fiber sensors into parts made of metal alloys with high melting temperatures. Fiber Bragg Grating (FBG) sensors were selected as the most promising

stimulated emission of radiation. The laser produces a coherent source of light with a narrow beam and a narrow spectral bandwidth (about 2cm). Lasers in fiber optics are usually solid-state semiconductor types. Lasers are used to provide the high-powered‚ tightly controlled light wave lengths necessary for high-speed‚ long-distance optical fiber transmissions. 4. Output Pattern: A setting that selects the output pattern for comparison outputs. This enables outputs for changes in levels rather than
