Abstract
Abstract LAN device and tools can be connected only by optical fiber cables without providing a space for additional LAN devices and tools and changing an electric connector interface of the LAN devices and tools already established. Heat radiation produced in a connector can be effectively discharged and electromagnetic wave can be prevented from radiating to an exterior of the connector
