Problems solved by technology

[0005] Obviously, the application of ointment has also caused the increase of cost, the pollution of the environment, and the difficulty of construction.
At present, although there are so-called all-dry optical cable structures at home and abroad, they put dry water-blocking materials and optical fibers or optical fiber ribbons together to achieve the purpose of water-blocking. Obviously, this water-blocking effect is not good in principle. reasonable

Abstract

The invention belongs to the technical field of optical cables, and in particular relates to an optical fiber ribbon cable. The optical fiber ribbon cable comprises a plurality of loose tubes out of a stiffener, a small filler arranged in an outer gap between adjacent loose tubes, protective layers out of the loose tube and the small filler, and a jacket layer coating the protective layer in extrusion molding. The cable is characterized in that a plurality optical fiber ribbons are in each loose tube, each optical fiber ribbon contains a plurality of optical fibers and ribbon resin for coating the plurality of optical fibers, the gaps formed between the loose tubes do not contain other visible filling substance except the optical fiber, the gap formed among the loose tube, the stiffener, the small filler and the protective layer does not contain visible filling substance. The optical fiber ribbon cable disclosed by the invention has the following main beneficial effects that the optical fiber has better ribbon water resistance performance, the optical cable is low in cost, low-carbon and environmentally friendly, light in weight, convenient for checkout and construction, and clean in production environment.

Description

[0001] This application is a divisional application of an invention patent application titled: Ribbon Resin and Optical Fiber Ribbon and Optical Cable Using the Resin, Application Number: 201410519527.5, and Application Date: October 05, 2014. technical field [0002] The invention belongs to the technical field of materials and cables, and in particular relates to ribbon-bonding resins and optical fiber ribbons and optical cables using the resin. Background technique [0003] As the main carrier of communication, the use of optical fiber is increasing day by day; at present, optical fiber is mainly used in the field of signal transmission, such as mobile phone signals, TV signals, control signals, monitoring signals, etc., and the commonly used optical fibers are silica-based optical fibers. The main light-transmitting part is the core. The core diameter is usually about 9 μm. The core diameter of multimode fiber is usually 50 μm and 62.5 μm. There is also a cladding outside...
