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 splitter and a beam coupler. The laser was operated in pulsed mode with a 75 ns pulse width which delivered an average power of 15 mW and continuous mode with a 50 % duty cycle. A preamplified Si PIN photodetector was used to detect the backscattered light. The fiber length measurement was compared utilizing a conventional Anritsu OTDR with an 850 nm wavelength. The length of the fiber obtained is 1313.99 m with a deviation of 0.46 % from a beam splitter measurement with a corresponding attenuation coefficient of 2.65 dBkm-1 with a deviation of 16.22 % and 1303.89 m with a deviation of 0.38 % for the beam coupler with the corresponding attenuation coefficient of 2.58 dB.km-1 with a deviation of 13.16 %
