Indoor visible light communication system under optical fiber fusion

The invention provides an indoor visible light communication system under optical fiber fusion, and the system comprises a photoelectric converter which converts an optical fiber signal transmitted by an optical fiber into an electric signal, transmits the electric signal to an access end signal transmitting module, converts the electric signal transmitted by an access end signal receiving module into an optical fiber signal, and inputs the optical fiber signal into the optical fiber; the access end signal transmitting module receives the electric signal transmitted by the photoelectric converter, balances and amplifies the electric signal to drive the first light emitting diode to transmit an optical signal, improves and flattens the frequency response of the first light emitting diode, and then transmits the optical signal to a user end; the user side converts the optical signal into a voltage signal meeting a network protocol standard and inputs the voltage signal to the network interface; and the access e
