Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] At present, the selection of the non-interference point of the optical switch is mainly realized by manual screening, the work efficiency is low, and the screening results are inaccurate. In view of the above problems, an embodiment of the present invention provides a method for selecting an interference-free point for an optical switch. f...

Abstract

Embodiments of the invention provide an interference-free point selection method and device for an optical switch. The method comprises the following steps of dividing channel points of the optical switch into a plurality of groups; aiming at any group, establishing a grid point matrix of the group, wherein the grid point matrix is composed of a plurality of grid points; if a relation between anyone of the grid points in the group and any one of the channel points meets a first preset rule, adding the channel point into a channel point set of the grid point; based on the size of the channel point set of each grid point in the group, selecting the to-be-matched grid points of the group; and aiming at all the groups, if a relation between the to-be-matched grid points of every two groups meets a second preset condition, taking the to-be-matched grid points of each group as interference-free points. According to the method and the device provided by the embodiments of the invention, automatic selection of the interference-free points of the optical switch is realized; the selection rate and the accuracy rate of the interference-free points are improved; and the condition is providedfor the optical switch to realize efficient and accurate interference-free channel switching.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of optical waveguide coupling, and in particular to a method and device for selecting a non-interference point for an optical switch. Background technique [0002] Optical switches and optical switch arrays are key devices in Optical Add-Drop Multiplexer (OADM) equipment, Optical Cross-Connect (OXC) equipment and optical routing equipment, with control signals in the same channel or The function of on-off and wavelength conversion between different channels is of great significance to solve the wavelength contention in the current complex network, improve the wavelength reuse rate and flexibly configure the network. [0003] As a new type of optical switch in the optical switch series, the two-dimensional MEMS optical switch (Micro Electro Mechanical System Optical Switch, MEMS OSW) has the characteristics of small size, low cost, low power consumption, fast speed and low loss. , so th...
