Rapid Progress of Transmission Bit Rates in Advanced Optical Communications Network for Germania Doped Silica and Fluoride Fibers

Abstract
In the present paper, design with practical data for parameters to maximized the transmission bit-rate, Br for improvement of performance in advanced optical networks with ultra-high speed long-haul repeater spacing and ultra wide-dense wavelength division multiplexing (UW-DWDM) technique for two optical transmission channels are processed, namely, Germania doped silica fibers and fluoride fibers. Five basic models of transmission bit rates techniques have been processed to investigated. The thermal effects are also considered through the thermal dependence of the channel links refractive index, chromatic dispersion and spectral losses. The set of variables which maximizes the bit-rate and the fiber length are possess negative correlations. It is also found that fluoride fiber is thermally stable than Germania doped fiber.
