Duplicated active and passive cabling appliances for super wide band frequencies through and Duplicated cabling system with the same

摘要

PURPOSE: A duplexing line device is provided to be capable of easily separating and classifying transfer lines with the plurality while maintaining independence of a high-frequency wide-band line device. CONSTITUTION: A duplexing line device comprises a plurality of active transfer units(2,3) which are provided in a metal casing in which a metal bulkhead(11) of a good conductor is formed. In order to prevent a counterpart active device from being affected by counterpart power supplying lines when a power is respectively supplied to each of the active transfer units(2,3) of the plurality, power supplying lines(24,25,34,35) are respectively arranged through penetration condensers(26,27,36,37).
