Embodiment Construction
[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0031] The optical signal transmission method for an indoor wireless network in an embodiment of the present invention includes the following steps:
[0032] Downlink optical signal transmission process: The optical signal sending end splits the optical signal transmitted by the outside world (optical fiber communication system), and the light of different wavelengths in the optical signal will be emitted along different directions during the splitting process; the optical signal transmitted by the outside world is generally DWDM (Dense Wavelength Division Multiplexing, Dense Wavelength Multiplexing) signal or CWDM (Coarse Wavelength Division Multiplexer, Sparse Wavelength Division Multiplexer) signal; The signal is sent to the user terminal after phase modulation.
[0033] Uplink optical signal transmission process: The optical signal transm...
