A corrosion-resistant optical cable

Abstract

The invention belongs to the technical field of optical cables, and specifically relates to a corrosion-resistant optical cable, which includes an outer sheath, a plastic coating, a metal armor layer, a water-blocking grease tube, an inner sheath, an optical fiber, a metal reinforcement, an Water belts, cooling fins, filler cords, reinforcement sleeves, wires, desiccant filler strips, elastic holes, transverse spacers and vertical spacers. In the present invention, a horizontal spacer and a vertical spacer are arranged in the inner cavity of the water-blocking ointment tube, so as to separate the ointment in the inner cavity of the water-blocking ointment tube, and ensure that when the entire optical cable is cut, through the vertical Reduce the loss of grease to the spacer, and prevent the oil from overflowing due to damage when the surface of the water-blocking grease tube is damaged through the transverse spacer.

Description

technical field [0001] The invention belongs to the technical field of optical cables, in particular to a corrosion-resistant optical cable. Background technique [0002] 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, and the outer sheath is covered. Some are also coated with an outer sheath to realize a communication line for optical signal transmission. [0003] The interior of the existing optical cable is generally filled with water-blocking...

AI Technical Summary

Problems solved by technology

[0003] 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
