OPTICAL CROSS-CONNECT DEVICE

摘要

An optical cross-connect apparatus optical nodes in an optical network, the optical nodes being mutually connected through internode connection optical fibers, the optical cross-connect apparatus having: optical cross-connect portions having internode connection input ports and internode connection output ports respectively connected to the internode connection optical fibers, and internal connection input and output ports, the optical cross-connect portions being connected such that an internal connection output port of a predetermined optical cross-connect portion is directly connected to an internal connection input port of another optical cross-connect portion and is indirectly connected via the another optical cross-connect portion to an internal connection output port of a further optical cross-connect portion, at least one optical cross-connect portion of the optical cross-connect portions including an internal connection input port and an internal connection output port for connecting to an optical cross-connect portion for expansion connected to none of the other optical cross-connect portions.
