Description
Technical field
The utility model is specifically related to a kind of joints of optical fibre axiality detection device.
Background technology
Optical fiber is fibre-optic abbreviation, is, using the total reflection principle of light, to be made up of glass, quartz or plastic or other material
Fiber, can be used as conduction light instrument.In actual application, optical fiber typically cannot be used directly, it is necessary to be installed
So as to meeting the application requirement of numerous and complicated in the precision machined joints of optical fibre.
The joints of optical fibre, be carry out between optical fiber and optical fiber can assembly and disassembly interface unit, it holds two of optical fiber
The accurate docking in face is got up, so that the light energy of launching fiber output can be coupled in reception optical fiber to greatest extent, so that
The impact that light path system is caused is minimized due to its intervention.For to a great extent, the quality of the joints of optical fibre is straight
Connect the reliability and remaining properties that have impact on optical transmission system.Conventional interface pattern has SMA, FC, ST and LC etc..
