Abstract
The influence of neutron and gamma radiation on single mode fiber cables is experimentally conducted. Attenuation due to incident radiation is measured. Attenuation is determined by laser source and power meter in Africa Teleco Company, besides attenuation recovery is attained. The Gamma experiment is carried out within Egypt Mega Gamma1 in National Center for Radiation Research and Technology of Egyptian Atomic Energy Authority (EAEA). In this experiment, the cable is degraded by gamma radiation of doses 5KGy, 10KGy, 15KGy and 25KGy and dose rate of 1KGy/26.4 min. However the attenuation based on neutron degradation is executed in the second Egyptian Training Research Reactor (ETRR-2), in front of neutron beam facility (NBF) in ETRR-2 which has a flux of 1.5x107(n/cm2.sec). For both experiments, the experimental measurements are done at two different spectral wavelengths of 1310 nm and 1550 nm. A comparison between obtained results is investigated.
