Abstract
A kind of bending-insensitive multi-core fiber is proposed. The core adopts a low-mode gradient index structure to form a seven-core few-mode fiber. The finite element method is used to simulate and analyze the bending loss of the center core and the outer core, the crosstalk characteristics between modes, and the influence of core parameters on the crosstalk performance. Data simulation results show that when the bending radius of this multi-core fiber is 5mm, the bending loss is much lower than the fiber attenuation loss, and the crosstalk between adjacent cores is less than -20dB. Therefore, independent information transmission between cores can still be realized under a small bending radius.
