Aluminum optical cable

Abstract

The invention discloses an aluminum optical cable, which is characterized in that: a U-shaped groove is formed on a metal aluminum wire along a longitudinal direction, and after optical fibers are placed in the groove, the U-shaped opening is sealed in a mode of friction welding and thus, the optical cable is manufactured; the friction welding is stirring friction welding; waterproof factice which may be heat-conducting waterproof factice is filled around the optical cable; and a macromolecular protective layer is formed outside the metal aluminum wire. The optical cable disclosed in the invention is simple and firm in structure, convenient for use, ratproof, high temperature resistant and low in cost and has a bright market prospect.

Description

Technical field [0001] The present invention relates to an optical cable, more specifically an optical cable with a substantially all-aluminum structure. Background technique [0002] With the development of optical communication, in addition to the application of optical cables between trunk lines and communication stations, more and more developments are made towards fiber to the roadside, fiber to the building, fiber to the home and fiber to the desktop, that is, the use of short distances The number of cores is increasing, and the number of cores is also decreasing. Fiber-to-the-home and fiber-to-the-desktop generally only need one to two cores, and the requirements for optical cables are also changing. They require features such as rat-proof, pressure-proof, fire-resistant and flame-retardant, easy to operate, and low cost. At the same time, optical fiber sensing technology is also advancing rapidly, and the requirements for optical cables are becoming more and more str...

Problems solved by technology

[0002] With the development of optical communication, in addition to the application of optical cables between trunk lines and communication stations, more and more developments are made towards fiber-to-the-road, fiber-to-building, fiber-to-the-home and fiber-to-the-desktop, that is, the use of short distances The number of cores is increasing, and the number of cores is also decreasing. Fiber-to-the-home and fiber-to-the-desktop generally only need one to two cores, and the requirements for optical cables are also changing, requiring features such as rat-proof, pressure-proof, fire-resistant and flame-retardant, easy to operate, and low cost. At the same time, optical fiber sensing technology is also advancing rapidly, and the requirements for optical cables are becoming more and more stringent. For example, optical fiber temperature sensors require the characteristics of thin diameter optical cables, rodent proof, high temperature resistance, fire retardant, and high thermal conductivity. It is mainly completed with high-density polyethylene + steel (or aluminum) tape armor + PBT materials, and its properties such as rodent resistance, high temperature resistance, fire resistance, and thermal conductivity can no longer meet the requirements of use.
