Specific implementation mode
The present invention is described in detail with reference to embodiment：
Such as attached drawing 1 and Optical Cables for Shipboard embodiment disclosed by the invention shown in Fig. 2, including optical fiber 1, optical fiber 1 be with
Bending radius is small and a diameter of of moisture-proof function is not more than 0.6mm coatings and nylon hard-pressed bale second coating optical fiber；Form optical fiber list
The number of fibers of member is preferably 4, is twisted into fiber unit inner core 2 by 4 optical fiber, and outsourcing squeeze jacket forms optical fiber list
First (OFCC) 3；The material of squeeze jacket be any one in halogen-free anti-flaming polyolefin, zero halogen fire retardant polyolefin or flame retardant polyurethane or
Various material is combined flame retardant polyurethane；Further include center part, fiber unit is twisted into around center part described in 6 groups
24 core cable cores 4；The outer layer of cable core coats shape successively by reinforcer 5, oversheath 6 and wire sheathing 7 from inside to outside
At；The reinforcer 5 is aramid fiber, glass fibre, gathers to the double oxazoles of benzo benzene or carbon fibre materials, to protect optical fiber to exempt from
It is influenced by external mechanical stress, improves the mechanical performance of optical cable；One layer of oversheath 6 is wrapped up in 5 outer surface of reinforcer；Oversheath
6 can be any in halogen-free anti-flaming polyolefin, zero halogen fire retardant polyolefin or flame retardant polyurethane or various material composition；Outer layer metal is compiled
Tissue layer 7 be stainless steel wire or or equivalent mouse bite preventing material similar structures, to protect cable core from the influence of external mechanical stress,
Improve the mechanical performance of optical cable.
Below to novel optical fiber unit components of the present invention --- second coating optical fiber elaborates：
One layer of buffering coating material is coated outside optical fiber as primary coating, which mainly plays support and cushioning effect.
In optical fiber and primary coating forming process, 35 ± 10 μm of the thickness of primary coating is controlled, by primary coating fibre outer diameter control
System is in 315 μm of ± 15% ranges of Φ.It is required according to designed by primary coating layer structure, adjusts mold core, die sleeve up and down
The position in two core shift directions ensures primary coating concentricity ﹥ 85%, it is ensured that optical fiber is in coating centre bit always
It sets, keeps uniform, the rounding of primary coating and optical fiber coating concentricity.Due to the effect of buffer layer, make optical fiber and coating
During coating molding, it can not only reduce influence of the external force to optical fiber, avoid the generation of micro-bend decaying, and in high/low temperature
Bending decaying caused by coating is shunk when environmental change can be decreased obviously, while by improvement primary coating coating optical fiber tool
There are excellent anti-pressure measurement and bendability.From the aspect of structure size, then it should reduce the cross-sectional area of optical fiber coating coating,
The cross-sectional area that experiment also demonstrates reduction primary coating coating optical fiber is an effective side for improving temperature characterisitic
Method.When fiber geometries size is certain, one timing of buffer layer outer diameter, the temperature of its decaying of the different coated fiber of coated fiber outer diameter
Characteristic illustrates that coating outer diameter is bigger (i.e. optical fiber coating cross-sectional area is bigger), and the temperature characterisitic of coated fiber is poorer, and optical fiber passes
Defeated attenuation loss is bigger, directly or indirectly affects the effect of optical transport.
The method that tightly packaged fiber is made using one layer of nylon hard-pressed bale material is squeezed out outside coated fiber in secondary coating.Two
In secondary coating hard-pressed bale forming process, using nylon hard-pressed bale material and primary coating layer degree of cohering are good, processing performance is superior, temperature
The features such as range is wide, while secondary coating should be reduced to the maximum extent in hard-pressed bale forming process to primary coating layer optical fiber
Adverse effect.For material used by secondary tightly packaged fiber, consider that selection is approximate with the coefficient of expansion of optical fiber, Young's modulus is low
Material and compatible with an optical-fibre coating material, while will be in conjunction with the use environment of Optical Cables for Shipboard and the spy of condition
Point.Nylon hard-pressed bale material has good elasticity, and low temperature performance well, bending modulus are moderate, have both excellent temperature performance and machine
Tool physical property.Therefore, secondary coating use outside coated fiber squeeze out one layer of nylon hard-pressed bale material be made tightly packaged fiber compared with
It is suitable.It is worth noting that, unwrapping wire and the tension of take-up should be controlled in the operation process for making second coating optical fiber, put
Line tension control 2g ± 0.5%, takeup tension control in ± 5% ranges of 4g, avoid primary coating layer optical fiber hard-pressed bale at
Added losses may be generated during type by bending.Unwrapping wire, takeup tension rationally whether can obtain function admirable
The key of second coating optical fiber, as unwrapping wire, takeup tension are improper, or because the internal stress in coating can influence fiber unit member
The temperature performance and long-time stability of part.When significant change occurs for extraneous high and low temperature environment, cold-thermal effect institute under normal circumstances
Optical fiber can occur micro-bend under caused outer force effect, so as to cause micro-bend decaying, avoid and eliminate optical fiber occur it is micro-bend general
Rate.
Practice have shown that optical cable, which under conditions of high/low temperature, easy tos produce longitudinal contraction deformation, constantly squeezes optical fiber, lead to light
Fine added losses increase, and influence practical effect.The present invention, which uses, is not more than the secondary coated structured optical fiber institute of 0.6mm minor diameters
Optical Cables for Shipboard is made, selects coating layer thickness (or optical fiber coating cross-sectional area) appropriate that can effectively reduce optical fiber in height
Being affected by temperature under the conditions of temperature leads to characteristic variations.Fig. 3 illustrates the optical fiber of different coating cross-sectional areas (or coating outer diameter)
Characteristic is affected by temperature.
In conclusion to effectively improve optical fiber counter-bending at low ambient temperatures for the novel secondary covered structure that the present invention uses
Performance, be suitble under high/low temperature condition, improve cable core in temperature characterisitic, reduce optical cable inner fiber added losses；Also big simultaneously
It is big to improve the reliability and production yield rate of optical cable in use.Therefore novel secondary coated fiber system provided by the invention
At strand type multicore Optical Cables for Shipboard, have optical transmission performance excellent under harsh high and low temperature environment, also have make letter
The advantages that single, safe to use, long lifespan, wide fire-retardant, electromagnetism interference and excellent lateral pressure resistant performance and operating temperature range,
And it can effectively resist the destruction of the rodent in cabin.
The embodiment that the present invention records is only used for that the present invention will be described, does not constitute the limit to right
System.Other substantially equivalent replacements that those skilled in that art are contemplated that, in the protection domain of the present invention.
