A kind of optical hybrid cable

Abstract

The invention discloses a photoelectric hybrid cable comprising at least three optical fiber cables, at least six power cables, and at least one temperature measurement optical cable. Every two of the optical fiber cables abut against each other. Each optical fiber cable includes a plastic armored pipe provided with multiple hole channels, and optical fibers are arranged inside the hole channels of the plastic armored pipe. A first wrapping layer is arranged around the outside of the optical fiber cables, and is tightly connected with the optical fiber cables. The power cables are arranged around the outside of the first wrapping layer. Each of the power cables includes multiple conductors inside, which are surrounded by an insulating layer. A plastic hollow pipe of which the diameter is 5-10mm is arranged between every two adjacent power cables. A second wrapping layer is arranged around the outside of the power cables, and is tightly connected with the power cables. The temperature measurement optical cable is arranged in a cavity formed by the optical fiber cables. The photoelectric hybrid cable provided by the invention enables high-speed safe transmission of both power and information to be achieved, is easy to lay and low in material and labor costs, and has a long service life.

Description

technical field [0001] The technical field of optical cables of the present invention, in particular, relates to a photoelectric hybrid cable capable of simultaneously transmitting optical signals and electrical signals. Background technique [0002] Optical hybrid cable is a new type of access method, which integrates optical fiber and transmission line, and can solve problems such as broadband access, equipment power consumption, and signal transmission. [0003] With the rapid development of the national economy and society and the continuous improvement of people's living standards, the whole society has higher and higher requirements for safety, economy, and high-quality electricity consumption, and the pressure on the safe operation and management of power grids is increasing; at the same time, the needs of users The amount of information is increasing exponentially. The user's demand for exponentially increasing information cannot be met by traditional information tra...

AI Technical Summary

Problems solved by technology

However, the outer diameter of existing optical-electrical hybrid cables is generally large

In addition, because the optical fiber itself has the characteristics of thin diameter, soft quality, and light weight, the optical fiber is easily affected by external tension and external impact force applied to the cable, which leads to poor information transmission.
