, can coating when twist, coating material coating when be liquid, after through ultra-violet curing be solid-state after, this torsion
It can be packed on optical fiber cylinder.Due to this torsion of optical fiber be formed in pulling process, and on optical fiber cylinder both ends optical fiber without
Naturally relaxation release, in this way this torsion can be maintained on optical fiber cylinder inner fiber method.In after-combustion, discharged from optical fiber cylinder
Optical fiber, when be convergent on another fiber reel tool again, polarization maintaining optical fibre can show to restore original straightened condition because of this torsion
Power can experience this slight variation when collecting by the second optic fibre turning sensing device, and measure torsion direction and
Angular dimension allows optical fiber to restore straight and lays the foundation to discharge this torsion for subsequent rotation.In this course, back and forth
The speeds match that rotating can bring optical fiber to collect process has fluctuating, can by dancing wheel system and longer buffer fiber area
Effectively to calm down this fluctuating, thus coating damage of the optical fiber in after-combustion state caused by avoiding because of the fluctuating of speeds match bring.
The present invention is not limited to the above-described embodiments, for those skilled in the art, is not departing from
Under the premise of the principle of the invention, several improvements and modifications can also be made, these improvements and modifications are also considered as protection of the invention
Within the scope of.The content being not described in detail in this specification belongs to the prior art well known to professional and technical personnel in the field.
