Description

technical field [0001] The invention relates to the technical field of free space optical communication, in particular to a mobile optical communication transceiver and transceiver system based on an optical module architecture. Background technique [0002] Optical mobile communication is a strong and beneficial supplement to 5G mobile communication, and will also be an important part of future-oriented full-spectrum communication. The optical mobile communication system is generally divided into: a signal transmitting subsystem, a signal receiving subsystem, and an acquisition and tracking subsystem. The signal transmission subsystem is responsible for converting information into optical signals for transmission. The general processing method is: convert the information in the digital domain into analog electrical signals, and add bias voltage to the analog electrical signals to meet the characteristics of the laser components, and finally convert them into Optical signal...
