Light path switching method and an optical path switching control apparatus for an optical cross-connect equipment

摘要

PROBLEM TO BE SOLVED: To reduce the deterioration in signal quality due to a dynamic crosstalk generated at the optical path switching of an optical cross-connect apparatus with a simple and stable structure.;SOLUTION: When an optical path is switched from a first output port to a second output port by switching a light beam reflected on a first mirror from a second mirror opposite to the first output port to a third mirror opposite to the second output port, the existence/non-existence of a mirror opposite to other output ports on a straight line connecting between the second mirror and the third mirror is judged, the reflection angle of the first mirror is so controlled that the trajectory of the light beam linearly moves when the mirror does not exist therebetween, and the reflection angle of the first mirror is so controlled that the trajectory of the light beam circumvent other mirrors including the mirror when the mirror exists therebetween.;COPYRIGHT: (C)2007,JPO&INPIT
