jammers and communications equipment

May include a fiber optic cable, optoelectronic materials and integrated optoelectronic devices, optoelectronic devices, optical fiber communication devices (fiber optic passive components, fiber optic active device), optical fiber sensors, fiber lasers, Optical, optical fiber communication machines and equipment, fiber optic data transmission equipment; fiber-optic gyroscope; fiber-optic control of phased array radar, optical fiber ground and satellite communication systems, etc.. 320 more than our existing fiber optic communications companies, including fiber optic cable 193, and optoelectronic devices 46, 22 fiber optic materials and supporting enterprises, nine special instrument communication, optical communication transmission equipment 50. 24 billion yuan of output value, sales of 26.2 billion yuan. 65 means that the length of the battery of  laser pointer is 65mm.  laser pointer  will not work anyhow
During the Tenth Five-Year Chinese optical communications industry focus on the optical transmission, optical access, optical transmission products, fiber optic and optoelectronic devices five. Laser devices and applications (optics, physical optics, nonlinear optics, laser principles and techniques, optical information processing, etc.). Laser device (optical fiber, semiconductor, solid, gas, excimer, and other), laser processing, laser holography, laser medical equipment, laser ranging, laser radar, laser tracker, laser-guided, optical gyroscopes, traffic control systems, optical navigation equipment and systems, target designator, jammers and communications equipment. It means the green  laser pointer needs a little time for preheating.
Currently engaged in laser technology research, some more than 400 laser applications development and production units (excluding laser audio and video equipment production units), the national laser product market with annual sales of about 3.24 billion yuan (This data does not include laser audio and video equipment laser communications engineering, laser bar code detection and laser secondary benefits such as laser medical income, etc.). Optical information input and storage (electric and electronic technology, computer technology, optics-based).
