Description
Technical field
The utility model relates to optical fiber coating field, what be specifically related to is the mould of a kind of optical fiber in line coloring.
Background technology
Optical fiber is fibre-optic writing a Chinese character in simplified form, and is a kind of fiber be made up of glass or plastics, can be used as light conduction instrument.Transmission principle is ' total reflection of light '.First front Hong Kong Chinese University principal Gao Kunhe George A. Hockham proposes the imagination that optical fiber may be used for communication transfer, and therefore high Kun obtains Nobel Prize in physics in 2009.
Fine fibre-optic package, in plastics jacket, makes it to bend and is unlikely to fracture.Usually, the launching device of one end of optical fiber uses photodiode (light emitting diode, LED) or beam of laser that light pulse is sent to optical fiber, and the receiving trap of the other end of optical fiber uses photosensor to detect pulse.
In daily life, because light is more much lower in the loss of electric wire conduction than electricity in fibre-optic conduction loss, optical fiber is used as the information transmission of long distance.Photoconductive fiber is made up of the glass that two-layer specific refractory power is different.Internal layer is light inner core, diameter at several microns to tens microns, outer field diameter 0.1 ~ 0.2mm.
The refractive index ratio glass outer large 1% of general core glass.According to refraction and the total reflection principle of light, when the angle that light is mapped to inner core and outer bed interface is greater than the critical angle producing total reflection, the impervious interface of light, all reflects.
Usual optical fiber and optical cable two nouns can be confused.Most optical fiber before use must be coated by which floor operator guards, and namely the cable after coated is called as optical cable.The protective layer of fiber outer layer and insulation layer can prevent surrounding environment to the injury of optical fiber, Ru Shui, fire, electric shock etc.Optical cable is divided into: cable skin, aramid fiber yarn, buffer layer and optical fiber.Optical fiber is similar with concentric cable, does not just have mesh shields layer.Center is the glass core that light is propagated.
In multimode optical fibers, the diameter of core is 50 μm and 62.5 μm two kinds, roughly suitable with the thickness of the hair of people.And the diameter of single-mode optics fibre core is 8 μm ~ 10 μm, conventional is 9/125 μm.Core surrounded the low bulb envelope of one deck refractive index ratio core, and be commonly called as covering, covering makes light remain on in-core.Outside is the plastic wrapper that one deck is thin, i.e. coat again, is used for protecting covering.Optical fiber is bundled into bundle usually, and outside has shell to protect.The concentric double-layer cylinder that the cross-sectional area be normally made up of silica glass of fibre core is very little, its quality is crisp, easy fracture, therefore needs an additional protective layer.
Optical cable inner fiber is distinguished for convenience, by distinguishing at the outside upper different colours ink of external coating (EC).At present, optical fiber coloring technology is divided into two kinds, and a kind of colourless optical fiber color solidification again crossed for ultra-violet curing, another is lock look technology (namely secondary coating and pigmented layer stirring are all with again painted), and these two kinds of dye technology efficiency are low, affect production work efficiency.
