Distortion-resistance-type butterfly-shape optical cable

Abstract

The invention relates to a distortion-resistance-type butterfly-shape optical cable. The optical cable comprises reinforcement components (1), optical fibers (2) and a sheath (4). A center position of the sheath (4) is provided with the plurality of optical fibers (2). A cross section of the sheath (4) is a butterfly structure. The two reinforcement components (1) are arranged in the sheath (4) and are distributed on two sides of the optical fibers and are symmetrical about the optical fibers. Left and right sides of the optical fibers (2) are provided with two tearing ports (3). The tearing ports (3) are in a trapezoidal shape. A center connection line of the reinforcement components (1) is mutually parallel to a bottom line of the tearing ports (3). The optical fibers (2) are distributed on the two sides of the center connection line of the reinforcement components (1). The reinforcement components (1), the optical fibers (2) and the tearing ports (3) are not contacted with each other. The optical cable of the invention has the advantages that distortion-resistance performance is good; optical cable performance is stable; a service life is long; construction and laying are easy.

Description

technical field [0001] The invention relates to a dish-shaped optical cable, in particular to a twist-resistant butterfly-shaped optical cable. Background technique [0002] With the rapid development of the telecommunications industry, people's demand for bandwidth is getting higher and higher. Therefore, fiber optic access methods have been adopted at home and abroad. To the family) and other directions of development, the butterfly cable is widely used in the access network. For this reason, the communication industry of the People's Republic of China has formulated the standard YD / T 1997-2009 "Butterfly Drop Optical Cable for Access Network". However, at present, the shape of most optical cable splitting openings is a triangle or an approximate triangle with one corner facing the optical fiber. Such a structure makes the optical cable often be torn apart during a large amount of laying, which greatly shortens the life of the optical cable. [0003] Chinese patent appli...

Problems solved by technology

When this structure is twisted during construction, the tear will be separated naturally until the optical fiber or optical fiber ribbon, causing the optical cable to be torn, shortening the life of the optical cable and affecting product quality.
