Triangular cross section drop optical cable and manufacturing method thereof

Abstract

The invention relates to the technical field of optical cables and relates to a triangular cross section drop optical cable and a manufacturing method thereof. An outer sheath layer with an equilaterally triangular cross section coats three fiber units and a reinforcing assembly formed by a central reinforcing member and a central reinforcing member cushion layer to form the triangular cross section drop cable, wherein the central reinforcing member is placed at the midpoint of the equilateral triangle, the three fiber units are rotationally symmetric outside the central reinforcing member cushion layer and are arranged on three center lines of the triangle respectively, the outer sheath layer is provided with acute-angled separation grooves on both sides of each fiber unit, and the angular bisector of each separation groove points to the fiber. The triangular cross section drop optical cable is increased by 50% in fiber density and prevents repeated construction. The central reinforcing member cushion layer uses a foaming process. The central reinforcing member uses a high-flexible aramid fiber rod so as to decrease 30% unit weight. The optical cable is good in bending performance, reduces construction cost and construction difficulty. A tight sleeve layer uses nylon material to improve the anti-pressure ability of the branched fiber. The optical cable is suitable for urban networks and access networks.

Description

technical field [0001] The invention belongs to the technical field of optical cables, in particular to a lead-in optical cable with a triangular cross-section and a manufacturing method thereof. Background technique [0002] In recent years, urban networks and access networks have developed rapidly. The construction of 4G networks, including the recently proposed 5G network, has become the focus of competition among operators. They have increased investment in network construction to expand their market share. [0003] At present, there are various indoor wiring products and construction methods. Butterfly optical cables with a single optical fiber are commonly used on the market. The main effect is on the aesthetics of the interior, including under the carpet and on the walls. Therefore, there is a need for a lead-in optical cable with high optical fiber density, low construction difficulty, and does not affect the indoor appearance. Contents of the invention [0004] ...
