Embodiment

[0049] a kind of like figure 1 The pressure-resistant optical cable shown includes:

[0050] From the inside to the outside, the cable core 100, the aluminum-plastic composite tape 200 and the sheath layer 300;

[0051] The aluminum-plastic composite tape 200 wraps the cable core 100 to protect the cable core 100, and the sheath tightly covers the outer surface of the aluminum-plastic composite tape 200 to form a complete optical cable structure;

[0052] The cable core 100 includes several optical fiber wires 101 and a central strength member 102. The optical fiber wire 101 is formed by covering a single-mode or multi-mode optical fiber with a plastic sheath 500, and its interior is filled with water-blocking yarn or water-blocking powder to increase the hardness of the optical fiber wire 101, further Shape the optical fiber line 101 and improve the compressive performance of the optical fiber line 101 to a certain extent. The central strength member 102 is located at the ge...

Abstract

The invention relates to the field of optical cables, in particular to a pressure-resistant optical cable. It includes: a cable core, an aluminum-plastic composite tape and a sheath layer arranged sequentially from the inside to the outside; the cable core includes a central strength member and an optical fiber cable; the optical fiber cable is composed of a plastic sleeve covering an optical fiber, and is evenly arranged on the central strength member in the circumferential direction The outer surface of the aluminum-plastic composite tape and the sheath is provided with an elastic anti-pressure layer, and the elastic anti-pressure layer is formed by a spring tightly wound on the outer surface of the aluminum-plastic composite tape; the central reinforcement is also composed of a spring; the elastic The thread pitch of the anti-pressure layer spring is larger than that of the central reinforcement spring. The invention greatly improves the radial compression resistance of the optical cable, controls the preparation cost of the optical cable, and has higher cost performance and structural stability.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to a pressure-resistant optical cable. Background technique [0002] Optical cable is a common cable for optical signal transmission in the field of communication. It has developed rapidly in recent years and produced various optical cables. [0003] Among them, GYTA optical cable is a common light-weight optical cable, which is similar in structure to GYTS optical cable. The plastic composite tape has a weak ability to resist radial pressure, and it is very easy to deform and damage when subjected to significant radial pressure, resulting in a rapid decline in optical signal transmission performance. Contents of the invention [0004] In order to solve the existing optical cables, especially the optical cables with insufficient strength of materials such as GYTA optical cables, the ability to resist radial pressure is weak, and when subjected to radial pressure, it is very easy to ...
