ULTRAHIGH FREQUENCY BAND COMBINER AND NETWORK SYSTEM USING THE SAME

摘要

PURPOSE: An ultrahigh frequency band combiner and a network system using the same are provided to reduce loss of a data signal between a first data transceiving unit and a second data transceiving unit by using a frequency band combiner and a band combiner. CONSTITUTION: A light source unit(110) outputs a beam in a first wave length band and a beam in a second wave length band. A first combiner(130a) combines the output beam from a second port of a second circulator(150a) and the beam in the first wave length band. The first combiner inputs the combination beam on a third port of a first circulator(150b). A second combiner(130b) combines the output beam from a second port of the first circulator and the beam in the second wave length band.
