Anti-disaster optical cable

Abstract

The invention discloses an anti-disaster optical cable which comprises a communication optical fiber, a metal hose, an aramid fiber layer, a metal woven mesh and an optical cable outer sheath. The communication optical fiber is coated by the metal hose; the metal hose is coated by the aramid fiber layer; the aramid fiber layer is coated by the metal woven mesh; and the metal woven mesh is coated by the optical cable outer sheath. The invention solves the following problems that (1) a conventional communication optical cable has large volume and heavy weight and is beneficial to rapid communication, however, the net weight of the anti-disaster optical cable disclosed by the invention is much lower than the weight of the conventional communication optical cable, so that the anti-disaster optical cable is convenient to construct and ensures the rapid net construction; and (2) a conventional light optical cable has low mechanical intensity and the conventional light optical cable has small volume and light weight, but is only suitable for indoor communication and cannot meet the requirement of the outdoor optical cable communication on the strength due to the insufficient tensile force and side pressure resistance when being used outdoors. However, due to the action of the metal hose and the metal woven mesh, the optical cable disclosed by the invention has the mechanical strength which is not lower than that of the outdoor communication optical cable, and meets the requirement on the outdoor optical cable application.

Description

technical field [0001] The invention relates to a disaster-resistant optical cable, especially a small-sized, light-weight and high-strength disaster-resistant optical cable with optical fiber as the main body, which is used for emergency communication after natural or man-made disasters, and belongs to the field of optical technology. Background technique [0002] During natural disasters, power and communications are often disrupted. Especially after the communication is interrupted, the disaster area and the outside world cannot be contacted, and it is impossible to guarantee timely disaster relief and rapid recovery of communication in the disaster area. Due to the large size and heavy weight of traditional communication optical cables, a lot of manpower and equipment support are required for wiring in disaster areas. Moreover, the optical cable is extremely inconvenient during transportation, which is not conducive to the rapid restoration of communication and rapid ne...

AI Technical Summary

Problems solved by technology

Especially after the communication is interrupted, the disaster area and the outside world cannot be contacted, and it is impossible to guarantee timely disaster relief and rapid recovery of communication in the disaster area

Due to the large size and heavy weight of traditional communication optical cables, a lot of manpower and equipment support are required for wiring in disaster areas

Moreover, the optical cable is extremely inconvenient during transportation, which is not conducive to the rapid recovery of communication and rapid network construction.

At the same time, although the traditional light optical cable is small in size and light in weight, it is only suitable for indoor communication. When used outdoors, it cannot meet the strength requirements of outdoor optical cable communication due to its insufficient tension and lateral pressure resistance.
