Abstract

The invention provides a light switching device and method, and relates to the field of fiber communication. The light switching device comprises first and second light switching unit, a control module and a first fiber unit; the first light switching unit comprises N first light switching modules; the second light switching unit comprises N second light switching modules, and is used to switch atransmission path of an optical signal; the control module controls switching of the transmission path of the optical signal in the light switching device; and the first fiber unit comprises N first fiber subunits corresponding to the N first light switching modules, each first fiber subunit comprises N first fibers, one end of each first fiber is connected with the first light switching module corresponding to the first fiber subunit, the other end of the each first fiber is connected with the corresponding second light switching module, and N represents a positive integer greater than 1. Thus, paths of optical signals can be switched randomly.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to an optical switching device and method. Background technique [0002] With the rapid development of optical fiber communication technology, more and more optical devices are used to control the change of optical signal transmission path. [0003] In the prior art, an optical switch is generally used to change the transmission path of an optical signal input to the optical switch. The optical switch uses technologies such as electrostatic force, electromagnetic force, electro-optic effect, magneto-optical effect or optical nonlinear effect to control the on-off of the optical path. In the technology of the optical switch, the optical switch mainly controls the optical signal transmission path by controlling the on-off of the optical path. In the process of optical fiber communication, in scenarios such as optical fiber scheduling is required, the optical switch cannot ...
