Description
Technical field
The present invention relates to a kind of low water peak single mode fiber and production technology thereof, be specifically related to little cladding diameter low water peak single mode fiber and production technology thereof that a kind of coating is easy to peel off.
Background technology
In the optical cable use procedure, especially in the fiber-to-the-home application of FTTX, need the stable optical fiber of rapid construction and cladding diameter, yet low water peak single mode fiber product of the prior art, cladding diameter is generally wanted deviation 0.7 μ m, and deviation range is larger, and the coating stripping dynamics is higher, be higher than more than the 1.5N, in making the optical cable stripping process, peeling force is larger, and peels off the rear surface and produce the coating residue is arranged, can not realize rapid construction, bring inconvenience to construction.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of cladding diameter distributional stability in order to solve deficiency of the prior art, and rear low water peak single mode fiber without coating remnants and production technology thereof can disposablely be peeled off and peel off to coating.
Technical scheme: the little cladding diameter low water peak single mode fiber that a kind of coating of the present invention is easy to peel off, the cladding diameter of described optical fiber are 124～125 μ m, and the internal coating diameter is 190～200 μ m, and the external coating diameter is 242～248 μ m.
The production technology of the little cladding diameter low water peak single mode fiber that a kind of coating of the present invention is easy to peel off, comprise: prefabricated stick drawn wire, coating and curing, described prefabricated stick drawn wire: the control feedback frequency of cladding diameter is set to adopt a little more than 3000 times in 1 second in the wire drawing PLC control system, simultaneously test is adopted point mode and change the Real-time Feedback pattern into by 50 modes that are averaging, the PLC feedback send bar mode to change the gradual change type variation into by original stepped change, adjusts every 5 degree; Described coating: apply coating and adopt modulus to be controlled at the ultraviolet-curing paint of 0.6～1.2MPa; Described curing: the curing oven general power is 1800～2400KW.
As preferably, ultraviolet light polymerization equipment is adopted in described curing.
As preferably, described coating and solidify between distance be 1～3 meter.
The present invention can effectively improve the stripping performance of fibre coating by to applying the improvement of coating; By the improvement to PLC control system in the drawing process, the stability of cladding diameter is obviously improved simultaneously, be narrowed down to deviation less than 0.3 μ m from deviation 0.7 μ m, greatly reduce the deviation of fibre cladding diameter.
Beneficial effect: low water peak single mode fiber cladding diameter distributional stability of the present invention, coating can disposablely be peeled off and peel off rear remaining without coating, for the propelling of the integration of three networks, broadband China cause huge contribution are arranged.
Embodiment
The little cladding diameter low water peak single mode fiber that a kind of coating is easy to peel off, the cladding diameter of optical fiber are 124～125 μ m, and the internal coating diameter is 190～200 μ m, and the external coating diameter is 242～248 μ m.
A kind of production technology of making above-mentioned low water peak single mode fiber may further comprise the steps:
(1) prefabricated rods is carried out wire drawing: prefabricated rods is assembled on the wire-drawer-tower, the beginning wire drawing, wherein the control feedback frequency of cladding diameter is set to adopt a little more than 3000 times in 1 second in the wire drawing PLC control system, simultaneously test is adopted point mode and change the Real-time Feedback pattern into by 50 modes that are averaging, the PLC feedback send bar mode to change the gradual change type variation into by original stepped change, adjusts every 5 degree;
(2) apply: the semi-manufacture optical fiber after the wire drawing is applied, apply coating and adopt modulus to be controlled at the ultraviolet-curing paint of 0.6～1.2MPa;
(3) solidify: the optical fiber after will applying is cured, and the distance between coating and the curing is 1～3 meter, solidifies and adopts ultraviolet light polymerization equipment, and the curing oven general power is 1800～2400KW, and curing oven quantity is 6～8;
(4) optical fiber after will solidifying carries out performance parameter test;
(5) optical fiber after will testing is reeled, and gets the finished product low water peak single mode fiber.
By to applying the improvement of coating, can effectively improve the stripping performance of fibre coating; Simultaneously by the improvement to PLC control system in the drawing process, the stability of cladding diameter is obviously improved, narrow down to deviation less than 0.3 μ m from deviation 0.7 μ m, greatly reduced the deviation of fibre cladding diameter, cladding diameter can be controlled within 124～125 μ m again simultaneously.
Table 1 is the present invention and prior art fibre cladding diameter test comparison table, can be found out by table, cladding diameter deviation is larger in the prior art, and the cladding diameter of the optical fiber that the present invention produces then deviation is less, and cladding diameter is controlled in 124～125 μ m all the time.
