Field cable and making method thereof

Abstract

The invention provides a field cable comprising a plurality of light units arranged closely in the center of the cable, a reinforcing water-blocking layer wrapping the outer sides of the light units,an inner sheath wrapping the outer side of the reinforcing water-blocking layer, a braiding layer armored at the outer side of the inner sheath, and an outer sheath layer formed at the outer side of the braiding layer in an extrusion molding manner. According to the field cable provided by the invention, the light units are made of nylon tight-sleeved optical fibers, so that the good mechanical and electrical insulation performances are realized; and because of the low water absorption rate, the moisture intrusion is prevented. Besides, since the braiding layer protect the inner sheath layer,the reinforcing water-blocking layer and the light unit, the bite damage by the rodent is prevented, so that the service life of the cable is prolonged. In addition, the invention also provides a method of making the field cable.

Description

technical field [0001] The invention relates to the technical field of optical cable communication, in particular to a field optical cable for field communication and a manufacturing method thereof. Background technique [0002] With the development of economy and society and the enhancement of national defense and military strength, the focus of modern military communications has been placed on meeting new data transmission requirements. In recent years, military exercises have continued to increase. In order to ensure the smooth communication of troops, the demand for field optical cables is increasing. , and its requirements are getting higher and higher. [0003] Field optical cables must not only adapt to fast wiring and repeated use, but also avoid dragging damage during the construction process. At the same time, it is necessary to consider the damage to communication lines caused by pests such as rats and ants. The existing field optical fiber cables generally use c...

AI Technical Summary

Problems solved by technology

The existing field optical fiber cables generally use colored optical fibers as the communication transmission unit. The optical fibers lack certain protection, and the optical fibers are prone to breakage during the construction process; they are armored with stainless steel wire hoses. Once damaged by animals, the internal optical fibers are easily damaged. The erosion of water vapor will cause poor communication for a long time; in addition, the tensile strength of existing field optical cables is low, which is not suitable for repeated construction in the field
