Benefits of technology

This technology makes it easier to make things that have better flexibility or durability than traditional methods like plastic pipes. Its technical effect includes being able to create small-diameter fibers without wasting material while still maintaining their desired properties such as resistance against impact forces and moisture ingress. Additionally, this new method allows for direct processing into different shapes and sizes, making them more efficient compared to previous techniques.

Problems solved by technology

Technological Problem addressed by this patents relates to improving the design and efficiency of indoors containing multiple types of opaque fibers called Single Core Induced Plugging Ground Cable(SCG). These fibers require special treatment during their installation, which makes these fibers expensive and challenges when being installed within limited space inside buildings like houses without any obstacles. Additionally, they may break down easily if exposed outside because they cannot maintain good quality signals even after long periods of exposure time.

Embodiment Construction

[0019] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings.

[0020] It includes a bare glass optical fiber 1, a buffer layer 2 and a transition layer 3 are sequentially coated on the outer periphery of the bare glass optical fiber, and an outer protective layer 4 is coated on the transition layer.

[0021] The manufacturing process of the optical fiber is as follows: put the optical fiber preform 5 into the drawing furnace 6, heat and pull out the optical fiber, after the optical fiber is cooled by the outer diameter measuring instrument 7 and the cooling pipe 8, it is successively passed through two surface coating devices 9, 11 and 8. The ultraviolet curing device 10 is used to coat and cure the buffer layer and the coating and curing of the transition layer. After the optical fiber coated with the buffer layer and the transition layer is drawn out, it passes through the outer diameter measuring instrument

Abstract

The invention relates to an indoor-laying optical fiber and a manufacture method thereof. The optical fiber comprises a naked optical fiber, the periphery of the naked optical fiber is sequentially coated with a buffer layer and a transient layer, and the transient layer is wrapped with an external protection layer. The processing of the optical fiber is carried out on a same assembly from optical fiber pre-manufactured rod drawing, coating and extrusion molding to be formed in one step. The invention has the beneficial effects that: 1. the invention has simple structure, thin diameter, good bending performance, certain drawing-resistant capacity and flame-retardant water-proof performance, low cost and high cost performance; 2. the invention can be directly used for wiring the interior, ships and automobiles, and the wiring is continuous, convenient and room-saving; and 3. the whole optical fiber is formed from drawing in one step, thus enhancing working efficiency and lowering manufacture cost; and the processed optical fiber is good in quality and low in inner stress, can resist the influence of external force on the optical fiber during manufacturing and using, and avoid the damage and influence on the optical fiber caused by re-processing and heating on the optical fiber.
