A flexible optical fiber ribbon and optical fiber cable

Abstract

The application relates to a flexible optical fiber ribbon and optical cable, which includes several core ribbon groups, each core ribbon group is arranged side by side, and the core ribbon group includes three optical fiber units; the three optical fiber units of the core ribbon group are arranged side by side, and the The optical fiber unit includes an optical fiber, and the optical fiber unit in the middle includes at least one optical fiber arranged in parallel and connected; between two adjacent core band groups, and between two adjacent optical fiber units in the core band group, through A plurality of first connecting parts intermittently arranged along the length direction of the optical fiber are connected; the plane passing through the axes of two adjacent optical fibers is used as a reference plane, and the first connecting part includes two connecting units respectively located above and below the reference plane, A buffer cavity is formed between two adjacent optical fibers and two connection units above and below the reference plane. The present application can solve the problem in the related art that when the optical fiber ribbon is bent along the width direction, the resin is easily damaged, so that the flatness of the optical fiber ribbon is not good.

Description

technical field [0001] The present application relates to the technical field of optical fiber communication, in particular to a flexible optical fiber ribbon and optical cable. Background technique [0002] In recent years, with the vigorous advancement of the construction of "all-optical network", the construction of traditional underground access network is facing new challenges. On the basis of making full use of the original underground facilities, the demand for ultra-large-core and high-core-density optical cables is increasing. How to increase the core number of optical cables while maintaining the original outer diameter of optical cables has become the direction of exploration in the industry. The existing flat optical fiber ribbon has been paid special attention to because of its high density, high integration, light weight, and convenience for multi-fiber splicing. The size of optical cables with the same number of cores is also large, and it has been unable to ...
