Abstract
The present invention discloses a kind of non-circuit symmetric fiber with side identification mark, including fibre core and covering, and covering outermost, which makes, side identification mark.Identification mark run through the non-circuit symmetric fiber of whole piece, by side it is observed that identification mark, is identified during to axle with this and labeled as datum mark to axle, substantially reduce to axle difficulty.
Description
Technical field
The present invention relates to fiber optic communication field, the specifically non-circuit symmetric fiber with side identification mark.
Background technology
The technology of preparing of present optical fiber mainly has pipe rod technology, double crucible technique, sol-gel technique, outside vapor deposition
Method (OVD), axial vapor deposition method (VAD), modified chemical vapor deposition process (MCVD) (MCVD), plasma activation chemical vapor deposition
Area method (PCVD) etc., being related to special optical fiber also includes some other method.
But non-circuit symmetric fibers all at present, including polarization maintaining optical fibre, multi-core fiber, photonic crystal fiber and special type
Optical fiber, it is difficult to find its difference from side.And in the handshaking procedure such as the welding of non-circuit symmetric fiber and cold joint,
In view of mould field matching or the matching problem of polarization state, it is required to rotate it to a common cross-wise direction and is connect
It is continuous.And these optical fiber is extremely complex to axle process, it is related to image recognition and processing, increases the complexity of structure and soft or hard
The difficulty of part.
Publication No. CN 101156099A entitled " fiber optic collimator instrument system, optical fiber collimator array, fiber optic collimator
The invention of the manufacture method of instrument system and optical fiber collimator array system ", by fused fiber splice by containing from materials such as titanium dioxide
Expect special without using sticky material, optics when the grin lenses that the quartz glass as refractive index adjustment material is formed bond with optical fiber
Property will not deteriorate, and by the self-align effect of solvent heat, grin lenses and optical fiber can easy aligning.
Although above-mentioned aligning mode, can be very big by making the index distribution constant of grin lenses in appropriate scope
Reduction coupling loss, avoid deterioration in optical properties, but with the continuous development of photoelectric technology, the application for special optical fiber
More and more, wherein polarization maintaining optical fibre and photonic crystal are phased with its unique performance.But on polarization maintaining optical fibre and
The welding of photonic crystal fiber, it is impossible to which welding is carried out using common aligning mode.Because polarization maintaining optical fibre and photonic crystal fiber
There is its axially direction, when welding in addition to aligning to be carried out, also require that its axial angle will be also aligned, this
Require to observe its side, and rotated with rolling clamp to axle.Polarization-maintaining heat sealing machine in the past, the side observed using side
Method, but the regulation of previously used method is difficult, and different directions are imaged in, it is more complicated to axle principle.
The content of the invention
In order to solve the problems, such as that prior art is present, the present invention provides a kind of not rounded symmetrical beam with side identification mark
Fibre, it is to make the identification through whole piece optical fiber on the outside of the covering of non-circuit symmetric fiber to mark, can be observed by side
Marked to the identification, identified again with this labeled as datum line to axle, substantially reduce to axle difficulty afterwards.
The present invention adopts the following technical scheme that：Non- circuit symmetric fiber with side identification mark, including fibre core and covering,
Covering outermost, which makes, has identification to mark.
Described non-circuit symmetric fiber is polarization maintaining optical fibre, multi-core fiber, photonic crystal fiber or special optical fiber.
The shape of described identification mark can be square, semicircle, oval or triangle.
The material of described identification mark can be the refractive index material different from cladding index or and covering
Color different coloring matter or coloured crystal.
The present invention is in the case of property during not influenceing optical fiber mode fields and laser transmission, in non-circuit symmetric fiber
Covering outermost makes an identification being observed from side, through whole piece optical fiber and marked, and identification mark can be in light
Realize in fine manufacturing process, when optical fiber is to axle, as long as the identification mark on two optical fiber is corresponding upper, substantially reduce to axle
Difficulty.
