Method for processing novel optical cable for convenient movement

Abstract

The invention discloses a method for processing a novel optical fiber for convenient movement; the method comprises the following steps of: (1) manufacturing a fiber core: drawing the fiber core by using all-glass or quartz; (2) extruding a PP (Polypropylene) coated layer; (3) extruding a nylon jacket, wherein the extruded thickness of the nylon jacket is not less than 0.4 mm and the strength of the nylon is less than 25 MPa; the extrusion temperature of the nylon is controlled to a temperature of higher than 290 DEG C and no bubbles is produced; and the PP coated layer and the nylon jacket should be tightly combined while extruding. The method for processing the novel optical fiber for convenient movement has the following beneficial effects that: (1) the production is simpler and easier; (2) the production energy consumption is saved by about 50%; (3) the minimum size of an ordinary single-core optical cable is reduced from 2 mm to 1.3 mm and the material cost is reduced by a large margin; (4) the single-core optical cable has better performance; (5) the single-core optical cable is compounded in other cables to serve as mobile communication, video transmission and signal control, the near-distance transmission of shielded pairs is overcome and the outside electromagnetic interference to the shielded pairs is also overcome; (6) the single-core optical cable is compounded inside the other cables; after 5,000,000 times of life tests, the single-core optical cable has unchanged error and reflection; and (7) the impact resistance capability is strong.

Description

technical field [0001] The invention relates to a processing method for a novel optical cable that is convenient to move, and belongs to the technical field of optical cable processing. Background technique [0002] At present, the vast majority of optical cores are drawn from quartz or all-glass cores. Because the fiber core has the same brittle characteristics as glass, it is easy to break and has poor impact resistance. [0003] The fiber core made of quartz or full glass cannot be used directly, and only after the surface of the fiber core is extruded and compounded with materials such as nylon + HDPE + aramid yarn + PVC materials, it becomes a single-core optical fiber, and the single-core optical fiber is then After being cabled or put together to form a cable core, it becomes a multi-core optical cable after being processed again by aluminum bellows + HDPE sheath. [0004] Single-core optical cables are divided into tight-buffered optical fibers or loose-buffered op...

AI Technical Summary

Problems solved by technology

[0004] Single-core optical cables are divided into tight-buffered optical fibers or loose-buffered optical fibers, and single-core optical cables cannot be directly used in occasions with small bending and high moving frequency

The tight-buffered optical cable or loose-buffered optical cable that has been added is only suitable for fixed laying occasions, and cannot meet the requirements of high transmission frequency, low anti-interference, and shock resistance.
