A study of the optical parameters of plastic fiber-optic cables used in calibration systems of astroparticle physics experiments

Results of studying the optical properties of plastic fiber-optic cables widely used in astroparticle physics experiments are presented. The absorption of nanosecond light pulses and light dispersion are studied. The influence of mechanical bends of the cables and photon’s launch angles on the transmission time and attenuation of light signals in these cables are also studied.
