Abstract
The invention discloses a small coating diameter low water peak single mode fiber with a coating easy to peel and a production process thereof. The diameter of the fiber coating is 124-125mum, the diameter of an inner coating is 190-200mum, and the diameter of an outer coating is 242-248mum. The production process is improvement for coatings in a wire drawing process and solidification equipment parameters and optimization on cladding diameter control feedback frequency and a programmable logic controller (PLC) feedback bar sending mode in a wire drawing PLC control system. The low water peak single mold fiber is stable in coating diameter distribution, the coating can be peeled in one time, no coating remains after peeled, and great contribution is made to improvement of three-network integration and boardband China industry.
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 stripping.
Background technology
In optical cable use procedure, especially in the fiber-to-the-home application of FTTX, need rapid construction and the stable optical fiber of cladding diameter, but low water peak single mode fiber product of the prior art, cladding diameter generally wants deviation 0.7 μm, and deviation range is larger, and coating stripping dynamics is higher, higher than more than 1.5N, making in optical cable stripping process, peeling force is comparatively large, and the generation of stripping rear surface has coating residues, can not rapid construction be realized, bring inconvenience to construction.
Summary of the invention
Goal of the invention: the object of the invention is to solve deficiency of the prior art, provides a kind of cladding diameter to distribute stable, and coating can disposable stripping and without the low water peak single mode fiber of coating remnants and production technology thereof after peeling off.
Technical scheme: a kind of coating of the present invention is easy to the little cladding diameter low water peak single mode fiber peeled off, and the cladding diameter of described optical fiber is 124 ~ 125 μm, and internal coating diameter is 190 ~ 200 μm, and outer coating diameter is 242 ~ 248 μm.
A kind of coating of the present invention is easy to the production technology of the little cladding diameter low water peak single mode fiber peeled off, comprise: prefabricated stick drawn wire, coating and solidification, described prefabricated stick drawn wire: in wire drawing PLC control system, the control feedback frequency of cladding diameter is set to adopt a little more than 3000 times for 1 second, test is adopted point mode simultaneously and be set to Real-time Feedback pattern, PLC feedback send bar mode to be set to gradual change type change, adjusts every 5 degree; Described coating: coating coating employing modulus controls the ultraviolet-curing paint at 0.6 ~ 1.2MPa; Described solidification: curing oven general power is 1800 ~ 2400KW.
As preferably, described solidification adopts ultraviolet light polymerization equipment.
As preferably, the distance between described coating and solidification is 1 ~ 3 meter.
The present invention, by the improvement to coating coating, effectively can improve the stripping performance of fibre coating; Simultaneously by the improvement to PLC control system in drawing process, the stability of cladding diameter can be made obviously to improve, narrow down to deviation from deviation 0.7 μm and be less than 0.3 μm, substantially reduce the deviation of fibre cladding diameter.
Beneficial effect: low water peak single mode fiber cladding diameter of the present invention distribution is stable, coating can disposable stripping and remaining without coating after peeling off, and the propelling for the integration of three networks, the Chinese cause in broadband has huge contribution.
Embodiment
Coating is easy to the little cladding diameter low water peak single mode fiber peeled off, and the cladding diameter of optical fiber is 124 ~ 125 μm, and internal coating diameter is 190 ~ 200 μm, and outer coating diameter is 242 ~ 248 μm.
Manufacture a production technology for above-mentioned low water peak single mode fiber, comprise the following steps:
(1) prefabricated rods carries out wire drawing: prefabricated rods be assembled on wire-drawer-tower, start wire drawing, in wherein wire drawing PLC control system, the control feedback frequency of cladding diameter is set within 1 second, adopt a little more than 3000 times, point mode is adopted in test simultaneously and change Real-time Feedback pattern by the mode that be averaging at 50, PLC feedback send bar mode to change gradual change type change into by original stepped change, adjusts every 5 degree;
(2) apply: applied by the semi-manufacture optical fiber after wire drawing, coating coating employing modulus controls the ultraviolet-curing paint at 0.6 ~ 1.2MPa;
(3) solidify: be cured by the optical fiber after coating, the distance between coating and solidification is 1 ~ 3 meter, and solidification adopts ultraviolet light polymerization equipment, and curing oven general power is 1800 ~ 2400KW, and curing oven quantity is 6 ~ 8;
(4) optical fiber after solidification is carried out performance parameter test;
(5) optical fiber after test is reeled, obtain finished product low water peak single mode fiber.
By the improvement to coating coating, the stripping performance of fibre coating effectively can be improved; Simultaneously by the improvement to PLC control system in drawing process, the stability of cladding diameter can be made obviously to improve, narrow down to deviation from deviation 0.7 μm and be less than 0.3 μm, substantially reduce the deviation of fibre cladding diameter, cladding diameter can be controlled within 124 ~ 125 μm again simultaneously.
Table 1 is the present invention and prior art fibre cladding diameter test comparison table, as can be seen from table, in prior art, cladding diameter deviation is comparatively large, and then deviation is less for the cladding diameter of the optical fiber that the present invention produces, and cladding diameter controls all the time within 124 ~ 125 μm.
