Claim 14:
15. The method of claim 14, wherein the controlling, by the beam switching array module, the plurality of beams of the second optical fiber light to be demodulated into the baseband signals via the first path or to be forwarded via the second path according to the polarization wavelength information comprises:
after receiving the polarization wavelength characteristic information transmitted by the high-speed bus, comparing, by the communication controller, the polarization wavelength characteristic information with a preset polarization wavelength characteristic information;
in response to that the polarization wavelength characteristic information is the same as the preset polarization wavelength characteristic information, controlling, by the communication controller, the optical switch to transmit the second optical fiber light to the communication transceiver board through the first optical fiber controller;
demodulating, by the communication transceiver board, the second optical fiber light, after obtaining the baseband signal, sending the baseband signal;
in response to that the polarization wavelength characteristic information is different from the preset polarization wavelength characteristic information, after controlling, by the communication controller, the optical switch to transmit the second optical fiber light to the second optical fiber controller through the first optical fiber controller, transmitting, by the second optical fiber controller, the second optical fiber light to the optical circulator; and
after transmitting, by the optical circulator, the second optical fiber to the third optical fiber controller, transmitting, by the third optical fiber controller, the second optical fiber light to a corresponding array element, so that the array element will forward the second optical fiber light, wherein the array element comprises the mirror group, the array displacement actuator, the coupling lens group and the divergence angle adjuster.
