Abstract
PURPOSE:To facilitate assembling, maintenance and expansion by providing a connection section of link or junctor connection between plural incoming multi-core optical connectors and plural outgoing multi-core connectors by an optical fiber in advance. CONSTITUTION:The link connection section 100 consists of optical fibers 330-338 linking the incoming multi-core connectors 110-112 and the outgoing multi-core connectors 120-122. The multi-core connectors 130-132 are provided to the output of grating switches 310-312 forming the primary switch and the multi-core connectors 140-142 are provided to the input of grating switches 320-322 forming the secondary switch respectively. The grating switches 310-312 and the link connection 100 are connected by the multi-core optical fibers 150-152 and the link connection 100 and the grating switches 320-322 are connected by multi-core optical fibers 160-162 to facilitate assembling, maintenance and extension.
