TLDR
This paper presents a multimode optical fiber design that has high tolerance to bending and it is observed that the proposed design is consistent with standard 50 μm graded index multimode fiber in terms of bandwidth and interconnectivity.Abstract:
This paper presents a multimode optical fiber design that has high tolerance to bending. Average bending loss per mode for a standard 50 µm graded index multimode fiber is 8.06E+08 dB/km for a bending radius of 1.25mm and particularly for fundamental mode it is 2.18E+02 dB/km. Whereas, simulation results show that average bending loss per mode in the case of the proposed bend insensitive multimode fiber for a bending radius of 1.25mm is about 2.67E-11 dB/km and particularly for the fundamental mode it is 1.96E-32 dB/km only. It is also observed that the proposed design is consistent with standard 50 µm graded index multimode fiber in terms of bandwidth and interconnectivity. Thus both can be spliced with the proposed design in the bending section.read more

Curvature loss formula for optical fibers
TL;DR: In this article, the curvature loss for optical fibers with constant radius of curvature of their axes is derived by expressing the field outside of the fiber in terms of a superposition of cylindrical outgoing waves.

Derivation of coupled power equations
TL;DR: In this paper, the authors derived coupled power equations from the coupled wave equations with the help of perturbation theory, where the coupling functions are random variables and the interaction between the modes can be described more easily by coupled power equation.

TL;DR: In this article, a bend-resistant design by introducing a microstructure into the solid core of the proposed fiber is proposed to avoid large bend distortion and the mode area will reduce accordingly.
