Problems solved by technology

[0003] It is well known that many 10G systems that have already laid optical cables still have a large number of unopened wavelengths. The laser carrier frequencies used in known communication systems are all at the low end of the spectrum: in the range of far infrared, infrared, and red light. High-end use of green and blue lasers and other higher carrier frequency optical communications

Embodiment 1

[0014] Embodiment 1, each of infrared, red, green and ultraviolet modulating lasers with optical fiber plugs is taken, and connected to the socket of the mixer arbitrarily. Send 10G image / voice / video signals to infrared, red, green, and ultraviolet rays respectively. After the signals are mixed into full-color by the mixer, they are sent to the transmission optical fiber connected to the mixer.

[0015] The other end of the optical fiber is inserted into the input connector of the optical splitter through the plug, decomposed by the optical prism and sent to the interface of the output socket correspondingly for each color light. Corresponding to the infrared, red, green, and ultraviolet sockets, the original light signal demodulated by the mixed light can be obtained.

Embodiment 2

[0016] Embodiment 2, each of the infrared, green, blue, and ultraviolet modulating lasers with optical fiber plugs is taken, and connected to the socket of the mixer arbitrarily. 10G or 40G image / voice / video signal / data stream signal is transmitted to infrared, green, blue, and ultraviolet rays respectively. After the signal is mixed into full color by the mixer, it is sent into the transmission optical fiber connected to the mixer.

[0017] The other end of the optical fiber is inserted into the input connector of the optical splitter through the plug, decomposed by the optical prism and sent to the interface of the output socket correspondingly for each color light. Corresponding to the infrared, red, green, and ultraviolet sockets, the original 10G or 40G image / voice / video signal / data stream optical signal demodulated by the mixed light can be obtained.

Abstract

The disclosed communication system is capable of simultaneous transmitting full color mixed from lasers in each color with wave band in 1mm - 10nm. Infrared, red, orange, yellow, green, cyan, blue, purple, and ultra violet lasers are as light source of carrier wave for transmission, and light source of local oscillation for reception. Independent mixer is utilized for encoding and hybrid transmission, and prism / grating array / filtering lens are utilized for demodulation so as to realize full spectral communication with mass data stream above trillion bits. The invention is applicable to point-to-point, ring-to-ring, FSO, and each network communication such as battlefield, disaster occasion, special urgency condition etc. or network communication between buildings and metropolitan area network etc.

Description

technical field [0001] The present invention relates to a laser carrier optical transmission method and application, in particular to a full-spectrum laser carrier optical transmission communication method and application. technical background [0002] At present, in the known public optical communication, one optical fiber can only transmit one monochromatic carrier optical signal at the same time, and the communication rate is realized by increasing the transmission density. For example, Germany and the United States have made this transmission rate reach 40G bits, but it has not yet realized commercial operation. It uses the addition of a new generation of grating waveguide array AWG and SONET technology to increase the information capacity of an optical fiber from 100 megabits per second to 100 megabits per second. seconds terabits. ("Optical Wave Communication" magazine, 2005, No. 2 and No. 4). They are all divided according to the wavelength interval specified by the...
