Ultra-microscopic air-blown cable and air-blowing cable process

Abstract

The invention relates to an ultra-microscopic air-blown cable and an air-blowing cable process. The cable comprises a loose tube which is wrapped with a plurality of optical fibers, and the loose tube is filled with fiber paste. An external protection sleeve is provided on the loose tube. A reinforced material layer is arranged between the loose tube and the external protection sleeve. The external side wall of the external protection sleeve is provided with a plurality of teethed gears in a circular manner. The end parts at the free ends of the teethed gears are provided with conductive layers which generate heat under the force of electromagnetic radiation. The cable blowing process is done as follows. A cable blowing machine and a silicon core pipe are located beneath the ground. And the cable blowing machine is communicated with one end of the silicon core pipe. The ground is further provided with a high-frequency electromagnetic heating device. The cable blowing machine sends optical fibers into the silicon core pipe through high-pressure air flows, and the high-frequency electromagnetic heating device moves in the extending direction of the silicon core pipe and conducts electromagnetic radiation towards the silicon core pipe. The inner wall of the silicon pipe is coated with lubricant.

Description

Technical field [0001] The invention relates to a new type of optical cable, in particular to an ultra-miniature air-blown optical cable and air-blown cable laying process. Background technique [0002] Air-blown micro-optical cable products have a wide range of applications. They can be used in long-distance trunk networks, as well as in all sections of metropolitan area networks and access networks, and more suitable for sections below the distribution cable. The use of air-blown micro-tube and micro-cable technology can enable telecom operators to effectively reduce construction costs in the future network upgrades and changes. As we all know, in the design of the air-blown micro-cable and micro-tube, the matching degree of the micro-cable and the micro-tube and the outer diameter size will have a greater impact on the air-blowing distance, thereby affecting the construction cost of the entire project. Therefore, it is necessary for us to develop a new type of small-size micr...
