Description

Technical Field

[0001] The invention relates to the field of cable installation, and in particular to a cable which is convenient for installing optical fibers. Background Art

[0002] Cable is a general term for items such as optical cables and electrical cables. Cables have many uses, mainly used for controlling installation, connecting equipment, transmitting electricity and other multiple functions. They are common and indispensable in daily life. Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic and can be used as a light transmission tool. Since optical fiber and electrical cable have different characteristics, optical fiber and electrical cable are usually installed separately, which requires a large amount of installation space for optical fiber and electrical cable; and because the installation is not synchronized, it will cause delays in installation work. The installation method of the prior art requires a large space, has a high demand for installation materials and labor, is costly, and is not conducive to maintenance and repair.

[0003] After searching in the publication (announcement) number: CN105913965B, a photoelectric hybrid cable is disclosed, which includes: at least 3 optical fiber cables, at least 6 power cables and at least 1 temperature measuring optical cable; the optical fiber cables are arranged in pairs; the optical fiber cable includes a plastic armor tube with multiple hole-like channels, and the optical fiber is arranged inside the hole-like channels of the plastic armor tube; the first sheath surrounds the outside of the optical fiber cable and is tightly connected to the optical fiber cable; the power cable is wrapped around the outside of the first sheath; each power cable includes multiple conductors; the conductor is surrounded by an insulating layer; a plastic hollow tube with a diameter of 5mm to 10mm is arranged between the power cables; the second sheath surrounds the outside of the power cable and is tightly connected to the power cable; the temperature measuring optical cable is placed in the cavity surrounded by the optical fiber cables.

[0004] Although the above solution can achieve high-speed, safe transmission of power and information through optoelectronic hybrid cables and is easy to lay, optoelectronic hybrid cables are integrated structures and are relatively expensive. In actual applications, if the optical fiber channel is not needed in the early stage of the project (for example, only for power supply or copper cable data transmission), then in order to effectively control the budget and avoid unnecessary expenses, you can choose not to install the optical fiber part temporarily, and only use traditional cable connections to meet current needs. However, adopting such a strategy also means that if business development requires additional optical fiber access in the future, it will face the challenge of rewiring. Summary of the invention
