Gamma-ray irradiation effects on distributed-feedback laser diodes

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

“…The basic formula for a typical optical fibre cable is an exponential decaying function as function of the fibre length L and initial transmitted power under thermal irradiation fields as the following expression [20,21] P R = P(I, T , f)e −sL (18) where P R is the received power after travelling in fibre length L through the lossy medium and σ is the radiation induced loss, σ, of several potential fibre optic material which was shown to obey an equation of the form [22]…”
