Title:
MULTI-CORE FIBER OPTIC CROSSTALK DETECTION METHOD AND APPARATUS, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/123651
Kind Code:
A1
Abstract:
A multi-core fiber optic crosstalk detection method, device and apparatus, and a computer storage medium. The multi-core fiber optic crosstalk detection method comprises: introducing a Kerr nonlinear effect to redefine a linear coupled-mode equation, so as to obtain a coupled-mode equation including a nonlinear influence (S101); calculating the total average value of electric field analytical solutions of a coupled optical fiber by using fiber optic parameters and by means of the coupled-mode equation (S102); rewriting the total average value of the electric field analytical solutions of the coupled optical fiber, so as to obtain a coupled power equation including the nonlinear influence (S103); calculating a coupled power of the coupled optical fiber by using the coupled power equation including the nonlinear influence (S104); and calculating, by using a transmission power, and the coupled power of the coupled optical fiber, a multi-core fiber optic crosstalk value including the nonlinear influence (S105). By means of the method, a coupled power equation, to which a nonlinear influence is added, is derived again, and on this basis, a brand-new nonlinear crosstalk estimation is obtained, and the nonlinear crosstalk estimation is more suitable for an actual fiber optic laying situation.
