Problems solved by technology
It shows that random core scrambling enables better performance in terms of error probability; however, random scrambling requires the installation of a large number of random scramblers, which causes additional implementation complexity and cost on the transmission system
[0019] Although existing solutions enable the reduction of crosstalk in multicore fibers, they fail to enable the estimation of core-dependent losses and the prediction of the performance behavior of optical transmission systems dependent on the value of core-dependent losses

Description
technical field [0001] The present invention relates generally to optical communications, and more particularly to apparatus and methods for core scrambling in multi-core optical fibers. Background technique [0002] Optical fibers are optical waveguides that guide electromagnetic waves in the light spectrum. An optical fiber includes a transparent core surrounded by a transparent cladding material having a lower refractive index. After a series of internal reflections, the light propagates in the fiber. Light carries data and allows long-distance transmission with higher bandwidth than wire-based or wireless communication systems. [0003] As Internet traffic increases, the amount of data traffic in optical communication networks expands exponentially. Due to the practical application of wavelength division multiplexing (WDM), coherent detection and polarization division multiplexing (PDM), as well as advanced signal processing, the transmission capacity and coverage of ...
