An optical communication system is provided for use with a communication network. The system includes a fixed site base station linkable to the communication network, and a plurality of fixed site subscriber units spaced from the base station. The base station includes a plurality of optical transmitters for transmitting communication signals through the atmosphere in the form of laser pulses, and a plurality of optical receivers for receiving communication signals through the atmosphere in the form of laser pulses. Each of the subscriber units includes an optical transmitter in optical alignment with one of the base station optical receivers for transmitting communication signals thereto through the atmosphere in the form of laser pulses, and an optical receiver in optical alignment with one of the base station optical transmitters for receiving communication signals therefrom through the atmosphere in the form of laser pulses. The laser pulses have wavelengths in the visible spectrum covering the wavelength range of 0.3 mu m to 30.0 mu m. |
