One of the key challenges in the design of a fibre optics system that degrades the system performance is the presence of bending, which should be carefully considered to ensure a reduction of losses in order to further increase the total carrying capacity. In this work, we present numerical simulations to examine bending loss in a newly designed high-capacity fibre with a large-core diameter of 200 µm and graded index profile (GI200 fibre) supporting a multiplicity of communication channels at a wavelength of 1.55 µm. In addition, we investigate the effect of bending on the periodic reconstruction phenomenon when four input channels are multiplexed into both a single bend and multiple bends of fibre under various bending conditions.
