WIPO Patent Application WO/2022/168205
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a small-sized optical switch that has low power consumption and is simple. The present invention is an optical switch characterized by comprising: a first multicore optical fiber having a plurality of cores on the same circumference from the center axis in a cross section perpendicular to the longitudinal direction; a first ferrule that incorporates the first multicore optical fiber; a second multicore optical fiber, the respective cores of which are disposed in positions corresponding to the plurality of cores of the first multicore optical fiber in a cross section perpendicular to the longitudinal direction; a second ferrule that incorporates the second multicore optical fiber and has the same outside diameter as the first ferrule; a split sleeve that accommodates the first ferrule and the second ferrule so as to cause the first ferrule and the second ferrule to face each other at the center axis; a slit interval adjustment tool for adjusting the interval of slits in the split sleeve; and a rotation mechanism for rotating either the first ferrule or the second ferrule about the center axis.
