ABSTRACT
The optic fiber are made up of glass or plastic for transmitting light signal over long and short distances providing nearly limitless bandwidth. This technology enables telecommunications service providers to send voice, data and video at ever increasing rate.
The focus of this study is toevaluate the measurement of temperature using fiber optic sensor using an OTDR to measure attenuation.
Data was acquired by placing the fiber optic cable inside a refrigerator at freezing temperature and allowing it to freeze while the other end was connected to a patch panel which was connected to an OTDR to interpret the signals, the cable was then brought out of the freezer and allowed to warm up while still connected to the patch panel and OTDR, the signals were also taken and recorded.
