DISPERSION COMPENSATION IN BINARY OPTICAL FIBER FOR ULTRA-MULTIPLEXINGS (SDM+WDM) APPLICATIONS

摘要

In this paper, the dispersion compensation is controlled via squeezing its level to any desired value in ultra-wide space division multiplexing (up to 200-link UW-SDM) system that employs 2400 channels in ultra-wide wavelength division multiplexing (UW-WDM). The process of compensation is done via the use of two successive sections of binary glass fiber, but of alternating total chromatic dispersions, that are squeezed to any desired value. The links are made of binary glass single-mode fiber under different thermal conditions. Each link possesses a central wavelength of its suboptical window, and consequently has its own design parameters { germania percentage, relative refractive index difference). The treated optical spectral window has 200-nm width ranging from 1450 nm up to 1650 nm, for the sake of parametric Raman amplification. Three-dimensional presentations are depicted to clarify the variations of the set of parameters {number of successive sections, germania percentage, relative refractive index difference}, at each link. The total number of links and consequently, the number of channels per link affects the designed set of parameters.
