Optical fibre communication cables systems performance under harmful gamma irradiation and thermal environment effects

Abstract

One problem in the application of fibre optics to military systems is that nuclear (and space) radiation is known to produce colour centres in optical materials, causing a reduction of light transmission over a spectrum of wavelengths. These radiation effects could cause permanent or temporary disruption of a fibre optics transmission system. Thus, the study has investigated the harmful effects of gamma irradiation on fibre communication system links under thermal environment effects over a wide range of operating parameters. Both the ambient temperature and the irradiation dose have severe effects on the system transmission link characteristics and consequently the performance characteristics of optical communication systems. It is also to be noted that the model has deeply developed the modelling basics of transmission communication systems, which may be used to analyse total pulse dispersion, transmitted signal bandwidth, transmission bit rates, radiation induced loss and optical received power by using the soliton transmission technique after different gamma irradiation doses and irradiation times. ©The Institution of Engineering and Technology 2013.
