Problems solved by technology

This kind of single-core indoor optical cable not only has a complex structure, but also makes the manufacturing process correspondingly complicated, and the production cost is high. Moreover, due to the large diameter of the optical cable and poor bending performance, it is difficult to adapt to some narrow wiring spaces for indoor laying.

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0022] It includes a glass bare optical fiber 1, a buffer layer 2 and a transition layer 3 are sequentially coated on the outer periphery of the glass bare fiber, and an outer protective layer 4 is coated on the outside of the transition layer.

[0023] 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 passes through two surface coating devices 9, 11 and The ultraviolet curing device 10 is used for coating and curing of 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 instrumen...

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.

Description

technical field [0001] The invention relates to an optical fiber suitable for indoor wiring laying and a manufacturing method thereof, belonging to the technical field of optical fiber communication. technical background [0002] Optical fiber has been increasingly widely used in the field of communication transmission due to its advantages such as wide transmission frequency bandwidth, large communication capacity, low loss, and low interference. In order to ensure the performance and life of optical fibers, existing optical fibers usually need to be coated with inner and outer sheaths and equipped with water-blocking materials and strength members to make optical cables before they can be used in communication transmission systems. With the rapid development of optical communication technology, optical communication transmission has been extended from the original core network and backbone network to the access network. In recent years, fiber optic access (FTTx) has beco...
