Embodiment Construction
[0030] The present invention will be further described in detail below in conjunction with the drawings and embodiments.
[0031] The optical signal transmission method for indoor wireless network in the 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 (fiber communication system). The light of different wavelengths in the optical signal will be emitted in different directions during the splitting process; the optical signal transmitted by the outside is generally DWDM (Dense Wavelength Division Multiplexing) signal or CWDM (Coarse Wavelength Division Multiplexer, sparse wavelength division multiplexer) signal; after the split optical signal is beam-expanded, the optical signal is transmitted according to the preset download wavelength The signal is phase-modulated and sent to the user terminal.
