Abstract

The invention provides an optical fiber line structure unit, which includes a metal bellows wrapped around the optical fiber from inside to outside, several carbon steel wires, stainless steel mesh, and an outer tube, and elastic supports are filled between the metal bellows and the outer tube material, one end of the outer tube is provided with a plug, the first clamping sleeve, and the other end of the outer tube is provided with a joint and a second clamping sleeve, and one end of the joint is inserted into the stainless steel mesh, and then passes through the second clamping sleeve Fixed, the other end of the joint is provided with a retaining ring and a sealing ring. The present invention also provides an optical fiber line, which includes several optical fiber line structural units connected end to end in sequence, and the metal bellows controlling the optical fiber line has an uninterrupted structure consistent with the optical fiber. The optical fiber line of the present invention provides sufficient protection for the optical fiber, the length can be designed, and the applicability is high; it can be bent to a certain degree and maintain a stable posture, and at the same time has a good vibration reduction effect, stretch resistance, waterproof, insulation, wear resistance, Easy to use.

Description

technical field [0001] The invention relates to the technical field of optical fiber protection devices, in particular to an optical fiber line structural unit and an optical fiber line. Background technique [0002] In the current laser transmission, the optical fiber is widely used because it can change the transmission direction of the optical path arbitrarily. However, under different bending postures inside the fiber, the internal stress of the structure is different, so it will have a certain impact on the transmission of polarized laser light. [0003] Armored optical fiber is to wrap a layer of protective "armor" on the outside of the optical fiber, which is mainly used to meet the requirements of customers to prevent rat bites and moisture. However, the existing optical fiber armor can only protect and seal the optical fiber to a certain extent, and its shape is very soft and cannot maintain a stable posture. Due to the limited working mechanism and process condit...
