Description
Technical field
The present invention relates to a kind of optical fiber more particularly to a kind of high-power glass optical fibers.
Background technique
Optical fiber is writing a Chinese character in simplified form for optical fiber, is a kind of fiber made of glass or plastics, can be used as light conduction tool.It passes
Defeated principle is the total reflection of light ' '.Fine optical fiber is encapsulated in plastic sheath, allows it to be bent and be unlikely to be broken.It is logical
Often, the emitter of one end of optical fiber uses light emitting diode (light emitting diode, LED) or beam of laser by light
Pulse is sent to optical fiber, and the reception device of the other end of optical fiber detects pulse using light-sensitive element.
In daily life, due to light in the conduction loss of optical fiber, light more much lower than the loss that electricity is conducted in electric wire
Fibre is used as the information transmitting of long range.
Existing glass optical fiber mostly uses silicate glass or phosphate glass as fibre core, and silicate glass is with respect to phosphoric acid
The advantage of salt glass optical fiber are as follows: there is preferable stability and can be welded with silica fibre, the advantage of phosphate glass optical fiber
Are as follows: efficiency of transmission with higher can reduce the length of activation optical fiber, and the inhibition with significant photon the Opacitization is imitated
It answers.The diameter of optical fiber directly influences the efficiency of transmission of optical fiber, and the thickness of surrounding layer directly influences the degree of protection to fibre core,
But the larger increase that will lead to volume of thickness.
Summary of the invention
The present invention in order to give full play to the advantage of phosphate optical fiber and silicate fibers, pass through balance fibre diameter realize it is high
Effect transmission.The present invention provides a kind of high-power glass optical fibers.
The technical solution used in the present invention are as follows: a kind of high-power glass optical fiber including fibre core and is placed in outside fibre core
Surrounding layer, the fibre core and the surrounding layer are glass material, and the core diameter is 80~90 μm, the outsourcing thickness
