Abstract

In this paper we report some experimental results concerning the measurement of the propagation losses, optical insertion and return losses of optical fibers using nondestructive methods. The attenuation of the optical power corresponding to an optical signal launched into the fiber was measured at λ =0.63 μ m with a bandwidth Δλ =0.03 μ m using the Optical Transmission Method. Also, using the Two Point Method and an Optical Time Domain Reflectometer we measured the attenuation of a single optical fibre having 28964 m for a 1 μ s laser pulse having λ =1.55 μ m. Based on an original set-up the optical insertion and return losses of optical fibers were measured for λ =1.55 μ m. In the case of the propagation losses for λ =1.55 μ m we performed an error calculation. The obtained results can be used in optical telecommunications, for the design of optical fiber sensors and other optoelectronic integrated circuits..
