Optical fibers performance parameters management under the control of spectral functional light sources with various wavelength windows and thermal effects

Abstract This paper has clarified the high speed performance signature of single-mode/multimode graded index silica-doped fibers in point to point link transceiver communication system. Fiber signal attenuation is studied versus ultraviolet wavelength region and different germanium dopant ratios added to silica fibers in point to point link. The fiber signal attenuation is also clarified versus near infrared wavelength region and different germanium dopant ratios added to silica fibers in point to point link. Fiber scattering loss is demonstrated against spectral operating wavelength region and different thermal effects of fiber temperature in point to point link. The modal fiber dispersion is investigated clearly and clarified in relation to fiber numerical aperture at different relative refractive index difference at operating spectral wavelength of 1,550 nm and 1,300 nm near infrared regions.
