Micro beam tube bow type drop optical cable

Abstract

The invention provides a micro beam tube bow type drop optical cable and belongs to the field of bow type drop optical cables. The micro beam tube bow type drop optical cable includes an optical cablebody. The optical cable body includes a protection sleeve, an optical communication unit and a reinforcement member; the protection sleeve is wrapped around outer parts of the optical communication unit and the reinforcing member; the optical communication unit includes a micro beam tube and at least four optical fibers, a plurality of optical fibers are arranged inside the micro beam tube, and the micro beam tube is made of polyolefin material. The bow type drop optical cable adopts a multi-core micro beam tube structure, high-density optical fiber distribution of the bow type drop optical cable is realized, and transmission performance of the optical fibers is not affected. Characteristics of small size, light weight, simple access mode and the like of a traditional bow type optic cableare retained while needs of great bandwidth access can be met. The optical cable disclosed in the invention is developed for future 5G and networks with improved speed access.

Description

technical field

[0001] The invention relates to the field of butterfly lead-in optical cables, in particular to a butterfly lead-in optical cable with micro-bundle tubes. Background technique

[0002] Traditional butterfly optical cables are generally divided into two types: outdoor self-supporting overhead and indoor introduction. In a typical butterfly cable structure, the number of optical fiber cores is 1-4 cores. The butterfly optical cable with a 4-core structure mostly uses optical fiber ribbons. During the production process In the process, it is easy to cause poor attenuation of the outermost fiber, and the pass rate and production efficiency are low.

[0003] With FTTH (FTTH is the English abbreviation of fiber direct to the home, the Chinese abbreviation of FTTH is fiber to the home. Specifically, FTTH refers to the installation of optical network units at home users or business users. The remarkable technical feature of FTTH is that it not only provides Larger b...
