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 field of fiber cable technology, in particular to a layer-stranded ribbon fiber cable for electric power or communication. The ribbon fiber cable comprises multiple loose tubes outside a reinforcing piece and a small filling rope in an outer gap of every two adjacent loose tubes. The loose tubes and the small filling ropes are provided with a protection layer outside. The exterior of the protection layer is coated by a sheath layer in an extrusion molding manner. The fiber cable is characterized in that multiple fiber cable ribbons are arranged in each of the loose tubes; each of the fiber cable ribbons is provided with multiple optical fibers and multiple fiber cable ribbon resin coating the whole optical fibers; there is no other visible filling matter except for the fiber cable ribbons in gaps of the loose tubes; and there is no visible filling material in gaps formed by the loose tubes, the reinforcing piece, the small filling ropes and the protection layer. The beneficial effects are that the fiber cable ribbons have quite high water resisting performance; cost of the fiber cable is quite low; the fiber cable is quite environmentally-friendly and light; detection and construction are quite convenient to perform; and production environment is quite clean.

Description

[0001] This application is a divisional application for an invention patent titled: Ribbon Resin and Optical Fiber Ribbon and Optical Cable Using the Resin, with an application date of October 5, 2014 and an application number of 201410519527.5. 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 outsi...
