Abstract

Disclosed are a many-to-many laser communication networking device and a method. The device includes: an optical field array control module, a transceiver lens array module, an array phase detection module, an array characteristic splitting module, a beam switching array module and a signal transmission module. The optical field array control module is configured to receive a plurality of beams of laser light with different angles, and adjust the corresponding angle of the laser. The transceiver lens array module is configured to convert the angle-adjusted laser into beams of second optical fiber light. The array characteristic splitting module is configured to analyze the second optical fiber light to obtain the second characteristic information. The beam switching array module is configured to control the second optical fiber light to be demodulated into baseband signals via a first path or to be forwarded via a second path according to the second characteristic information.
