METHOD FOR SHARING OPTICAL FIBER FOR CLOUD BASED NETWORK, SYSTEM AND APPARATUS THEREFOR

摘要

PURPOSE: An optical path sharing method for a cloud based optical path, a system, and a device thereof are provided to construct a cloud based network which connects a wired and a wireless donor unit group to a dispersed wired and wireless remote unit group. CONSTITUTION: A concentration device(210) multiplies either a summing signal or a wavelength conversion signal. The concentration device distributes the summing signal or the wavelength signal to a device which is connected through an optical share path. A dispersion device group generates an optical signal related to the dispersed summing signal or the dispersed wavelength conversion signal. The dispersion device group connects the optical signal or a wired signal to a wireless remote unit group or a wired remote unit group through the set optical path.
