Multicore Fiber Cable of Equal Performance for Ultrawide Wavelength Division Multiplexing in Optical Communications Networks

摘要

In the present paper, a novel technique based on multicore cable (N_c cores) for ultimate transmission capacity as well as the repeater spacing is suggested and employed where chromatic dispersion management is processed via squeezing. Fixed-radius fibers as well as fixed values of chromatic dispersion (near zero) are designed at variant thermal environmental conditions. Each core of the cable contains N_s space division multiplexed fiber links. These N_s links (carry 2400 channels ultra wide wavelength division multiplexing (UWWDM)) have its characteristics (radius, chemical structure, and optical structure) to achieve the same fixed chromatic dispersion at variant thermal environmental conditions. For ultimate transmitted bit rate, we suggested a system of multicores cables where the input moves from a core to other one if the thermal conditions are changed. This new core undergoes the same chromatic dispersion as the old one but with different geometrical and chemical structures. This suggested novel technique facilitates the design of good-high-speed cables in optical communication networks without severe reductions of the transmitted bit rate and the repeater spacing, and the signal-to-noise ratio.
