Double-core hidden leading-in optical cable

Abstract

The invention relates to a double-core hidden leading-in optical cable, and the optical cable comprises a sheath and optical fibers wrapped by the sheath. The optical cable is characterized in that the interior of the sheath is provided with two optical fibers in a parallel manner at an interval; the optical fibers are respectively wrapped by a tight sleeve layer; the adjacent sides of the tight sleeve layers of the two optical fibers are connected to form an 8-shaped tight sleeve layer; the 8-shaped tight sleeve layer is formed by the tight wrapping of transparent nylon, thereby forming an 8-shaped transparent nylon tight sleeve layer. According to the invention, the separated 8-shaped transparent nylon tight sleeve layer double-core optical fibers can directly enter a room for laying. The optical cable is convenient to lay, is easy to separate, is good in protective properties, is transparent, is good in hiding performance, and is good in construction effect. The optical cable is simple in structure, is easy to manufacture, is convenient to lay and use, and is especially suitable for occasions, in which the requirements for hiding performances are higher, of two-point following optical fiber home entry and optical fiber-to-desktop.

Description

technical field [0001] The invention relates to a double-core invisible lead-in optical cable, which belongs to the technical field of optical communication transmission. Background technique [0002] The introduction of optical cables in the fiber-to-the-home Internet transmission system plays a unique role in network transmissions such as buildings, digital communities, campus networks, and local area networks. At present, the commonly used drop optical cable is a single-core butterfly optical cable. The shape of the optical fiber cable is rectangular, and it has the characteristics of simple structure and convenient use. However, with the continuous expansion of the field of fiber-to-the-home applications, single-core drop cables are difficult to meet the requirements of actual use and laying, especially with the popularization of fiber-to-the-home and fiber-to-the-desktop, in many cases, the wiring of the fiber optic cable needs to be wired at two points , the use of a ...
