Composite leaky coaxial cable with embedded optical cable and method of making the same

Abstract

An optical cable-embedded composite leaky coaxial cable comprises an optical cable (1), a corrugated copper tube (2), a polyethylene foaming insulation layer (3), a slotted copper strip (4) and a polyolefin outer sheath (5); the corrugated copper tube (2) is internally coated with the optical cable (1), the polyethylene foaming insulation layer (3) is extruded outside of the corrugated copper tube (2), the polyethylene foaming insulation layer (3) is externally coated with a layer of slotted copper strip (4), and the polyethylene foaming insulation layer (5) is extruded outside of the slotted copper strip (4). With an optical cable embedded therein, the optical cable-embedded composite leaky coaxial cable is reasonably combined to form a composite structure, which ensures that the cable not only has the electrical performances of the leaky coaxial cable, but is also additionally imparted with the electrical performances of the optical cable; therefore, the cable is a multifunctional new product.

Description

technical field [0001] The present invention relates to a compound type leaky coaxial cable embedded with an optical cable and a manufacturing method thereof. Compared with a single leaky coaxial cable product, it not only retains all the performance advantages of the leaky coaxial cable, but also increases the cost of the optical cable. performance advantage. At the same time, the embedded design of the optical cable is adopted. During the process of transmitting the optical signal, the optical cable has a relatively stable external environment, which reduces the influence of uncertain factors in the external environment. Effectively guarantee the reliable and stable transmission of optical signal information. Leaky coaxial cables can make full use of the performance advantages of optical cables in a closed environment, effectively change the environment of the inner conductor, increase the transmission rate, and reduce attenuation. Thereby the invention relates to the embe...

Problems solved by technology

However, due to the fact that some public places require both leaky coaxial cables to provide an electromagnetic field environment for communication, optical cables are also required to transmit optical signals.

In an environment like a shopping mall, the space for placing cables is very limited, and it is not enough to install leaky coaxial cables and optical cables at the same time.
