Abstract:In the light of that the most disadvantage of plastic optical fiber (POF) was larger absorption loss, different kinds of loss factors were analyzed. Light absorption loss due to CH high harmonics vibrations in PMMA POF was calculated and simulated. And the Rayleigh scattering absorption loss and electronic transition absorption losswere quantitatively calculated. So intrinsic loss spectrum of PMMA POF was obtatined. The intrinsic absorption losses at different wavelengths were first calculated, and the results were consistent with measured data available in literature. It provided an important theoretical basis gist to reduce POF's loss.
