Title:
OPTICAL CROSS CONNECT UNIT, OPTICAL CROSS CONNECT DEVICE, AND NODE
Document Type and Number:
WIPO Patent Application WO/2024/075219
Kind Code:
A1
Abstract:
This optical cross connect unit switches the connection of a plurality of optical fiber core wires, the optical cross connect unit including: an optical switch that is provided to each of the optical fiber core wires; optical wiring paths that each connect between one of the optical switches and another of the optical switches; and an optical switch control part that controls the driving of the optical switches so that one length of optical fiber core wire is connected to one length in the optical wiring paths.
