Reflective type wireless optical-fiber communication system

Abstract

The invention discloses a reflective type wireless optical-fiber communication system. The reflective type wireless optical-fiber communication system comprises a plane mirror, a convex lens, a reflective type modulator, a silicon light cell panel, a demodulation and amplification circuit and a loudspeaker. Sunlight irradiates the plane mirror, plane mirror reflected light forms a convergent light beam through the convex lens, the convergent light beam irradiates the reflective type modulator to form an optical carrier wave of an optical modulation signal, the optical carrier wave irradiates the silicon light cell panel, the silicon light cell panel generates a corresponding electrical signal to be connected to the demodulation and amplification circuit, the signal after demodulation reduction and amplification is connected to the loudspeaker through the demodulation and amplification circuit, and the loudspeaker can play an amplified sound signal. The reflective type wireless optical-fiber communication system has the advantages of low cost, energy conservation, environmental protection, the wide frequency band, simple and flexible erecting, high anti-interference performance, good transmission secrecy performance and the like.

Description

technical field [0001] The invention relates to an optical fiber communication system, in particular to a reflective wireless optical fiber communication system. Background technique [0002] Due to the fact that the power of the optical signal in the current optical fiber communication will be lost during the transmission process, it largely determines the condition of no amplification and regeneration and the maximum distance allowed between the optical transmitter and receiver. At the same time, the manufacturing, installation and maintenance costs of amplifiers and optical repeaters are high, and the distortion caused by the transmission distance becomes more and more serious as the propagation path increases. Contents of the invention [0003] In order to overcome the defects in the prior art and solve the above technical problems, the present invention provides a low-cost, energy-saving and environment-friendly signal communication system. [0004] The invention pro...
