Corrosion-resistant optical cable

Abstract

The invention relates to a corrosion-resistant optical cable, which comprises an outer sheath (1), a water-blocking ointment tube (4) arranged in the outer sheath (1) and used for realizing a water-blocking function of the optical cable, and an inner sheath (5) arranged in the water-blocking ointment tube (4), wherein the inner side of the outer sheath (1) is connected with a metal armor layer (3)in a bonding manner, the outer side surface of the metal armor layer (3) is coated with a plastic coating (2), and the inner side of the metal armor layer (3) is connected to the outer side wall of the water-blocking ointment tube (4) in a bonding manner; a cavity is formed in the side wall of the water-blocking ointment tube (4); a transverse spacer (15) is connected into the side wall of the water-blocking ointment tube (4) in a bonding mode; and a vertical spacer (16) used for separating the inner cavity of the water-blocking ointment tube (4) is connected into the side wall of the water-blocking ointment tube (4) in a bonding mode. According to the structure, ointment in the inner cavity of the water-blocking ointment tube is separated, and it is guaranteed that when the whole opticalcable is cut, it is guaranteed that a large amount of ointment is prevented from overflowing due to damage.

Description

[0001] This application is a divisional application of an invention patent application with an application date of December 28, 2018, application number 201811627171.1, and the invention name "a corrosion-resistant optical cable". technical field [0002] The invention belongs to the technical field of optical cables, in particular to a corrosion-resistant optical cable. Background technique [0003] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. Optical cables It is mainly composed of optical fiber, plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value. The optical cable is a cable core composed of a certain number of optical fibers in a certain way, ...

AI Technical Summary

Problems solved by technology

[0004] The interior of the existing optical cable is generally filled with water-blocking grease, which can not only play a waterproof role but also enhance the corrosion resistance of the cable, but when the cable is cut or the surface of the cable is worn, it is easy to cause the grease to break down. loss, which will affect the corrosion resistance of the optical cable to a certain extent, and a certain amount of filling rope will be filled in the inner sheath of the optical fiber to prevent the fibers from being entangled together. If the optical cable is squeezed, it will easily cause the deformation of the filling rope and affect the normal operation The filling effect, and it is easy to cause the normal heat dissipation of the optical fiber
