A new optical time-domain reflectometer has been developed to investigate standard plastic optical fibers with PMMA as core material. The reflectometer allows to locate reflections and to obtain the fiber attenuation characteristics by analyzing the time dependence of the detected Rayleigh backscattered light. The measurement setup is working with 660 nm wavelength typical for transmission systems with PMMA fibers. Oversampling and digital signal processing including convolution and deconvolution decrease noise floor and increase the measurement resolution to the range of ten centimeters. more...
