Document Type and Number:
WIPO Patent Application WO/2022/201703
Kind Code:
A1
Abstract:
[Problem] To provide an optical transmission system that can improve convenience by flexibly handling combinations of a great variety of communication providers, frequency bands, and bandwidths, and construct versatile wireless areas, without undergoing large-scale system changes. [Solution] In an optical transmission system according to the present invention, a plurality of wireless transmission/reception units 101 that store frequency information for performing mapping of digital signals corresponding to communication providers, frequency bands, and bandwidths, are detachably stored in a wireless transmission/reception unit storage unit 100 of a master station 10, a control unit 114 reads frequency information from frequency information storage units 116 of the wireless transmission/reception units 101 inserted to the wireless transmission/reception unit storage unit 100, generates mapping information, and outputs the mapping information to an FPGA 113, and the FPGA 113 performs mapping of digital signals from the plurality of wireless transmission/reception units 101 on the basis of this mapping information.
