Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a point-to-point wireless communication module based on LI-Fi. Background technique [0002] With the development of intelligent communication technology, power line carrier and wired interconnection have gradually evolved into radio interconnection. Nowadays, radio interconnection has also taken an important step towards the future, and Li-Fi optoelectronic interconnection has appeared. Li-Fi photoelectric interconnection currently mainly has difficulties in realizing the lossless transmission of signal clocks. Due to the parasitic charge of the switch and the accumulation of the residual charge of the capacitive and inductive devices in the power supply circuit and the drive circuit, when the power is turned on next time, the amplitude of the impact charge at the moment of turning on is very high, and it is easy to be damaged after being superimposed with the par...
