Atmospheric laser communication system Features
Atmospheric laser communication system is developed by Gemming Laser Co., Ltd. It is a kind of point to point. optical fiber laser communication system used in the atmospheric Environment. It is composed of two sets of equipment that can be mutually transmit and receive information . Using single mode fiber laser and advanced information coding technology. There is a controller, a fiber laser transmitter and a laser receiver in each equipment.
Both equipment transmit /receive the modulated laser pulse signal to each other, and demodulate of the pulse signal from each other, So as to achieve the duplex communication.
Atmospheric laser communication system uses fiber laser with wavelength of 1.54μm (eye-safety wavelength)as the light source, The advantageous is as follows : High quality beam, Stable performance, strong penetration, can be used in bad weather situation to achieve a point to point communication at distance of 0.2~3km . anti-interference, good security . It is widely useful for field exploration operations and measurements.
