Fiber length and attenuation measurement by utilizing polarized beam splitter and fiber coupler in optical time domain reflectometer

In this study, attention was made to measure the length of the fiber and the coefficient of the fiber attenuation using novel configurations. Laser diode with a fundamental wavelength of (808 ± 10) nm with a maximum power of 50 mW was employed. The measurement was made by using a polarized beam spli...
