Structural units of optical fiber line, and optical fiber line

Abstract

The invention provides structural units of an optical fiber line, and the structural units comprise a metal corrugated tube, a plurality of carbon steel wires, a stainless steel mesh and an outer tubewhich are wrapped from the inside to the outside of the optical fiber, wherein an elastic support material is filled between the metal corrugated tube and the outer tube, one end of the outer tube isprovided with a plug and a first clamping sleeve, and the other end of the outer tube is provided with a joint and a second clamping sleeve, one end of the joint is inserted into the stainless steelmesh and then fixed through the second clamping sleeve, and the other end of the joint is provided with a retaining ring and a sealing ring. The invention also provides the optical fiber line comprising a plurality of structural units of the optical fiber line connected in sequence from end to end. The metal corrugated tube controlling the optical fiber line is of an uninterrupted structure, whichis consistent with the optical fiber. The optical fiber line of the invention provides sufficient protection for the optical fiber, can be designed in length to obtain high applicability, can be bentto a certain degree and maintain a stable attitude, and at the same time has good vibration damping effects, stretching and water resistance, insulation, abrasion resistance and easy 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...

Problems solved by technology

If an additional attitude fixing device is designed, firstly, it needs to be fixed in more places according to the length of the optical fiber, and secondly, the adjustment process will be limited by the actual structure and become more cumbersome
