Optical cable facilitating window opening and manufacturing method thereof

Abstract

The invention relates to the field of optical fiber communication and manufacturing, and discloses an optical cable facilitating window opening. The optical cable comprises an external sheath and an internal layer. The external sheath is internally hollow so as to form an accommodating cavity, and the accommodating cavity is provided with a long end and a short end. The internal layer is accommodated in the accommodating cavity, the internal layer is internally provided with optical fiber units, a gap is formed between the long end of the accommodating cavity and the external wall of the internal layer and the internal layer is clamped at the short end by the internal wall of the external sheath. Meanwhile, the external surface of the external sheath is provided with at least one pair of marking lines which extend along the cable length direction of the external sheath, and the position of a pair of marking lines is arranged in a way that the connecting line between each point arranged between the two marking lines and on the surface of the external sheath and the cable core of the optical cable is enabled to pass through the gap on the cross section of the optical cable. The invention also discloses a manufacturing method of the optical cable facilitating window opening. The accuracy of cable stripping can be effectively enhanced and damage to the optical fibers can be avoided.

Description

technical field [0001] The invention relates to the field of optical fiber communication and its manufacture, in particular to an easy-open skylight optical cable and a manufacturing method of the easy-open skylight optical cable. Background technique [0002] With the policy support of the "Broadband China" strategy by the state and relevant communication departments, and the rapid development of fiber-to-the-home, the use of optical cables in the distribution section and the home section of the optical fiber network has also increased rapidly. The optical fiber density, occupied space resources, construction, and laying of optical cables have high requirements. [0003] The types of optical cables commonly used in the distribution section include multi-core butterfly optical cables, multi-core distribution optical cables, and multi-core branch optical cables. If it is firmly wrapped, and the loose tube and the outer sheath are in close contact, it is impossible to accurat...

AI Technical Summary

Problems solved by technology

[0003] The types of optical cables commonly used in the distribution section include multi-core butterfly optical cables, multi-core distribution optical cables, and multi-core branch optical cables. It is firmly wrapped, and the loose tube and the outer sheath are in close contact. It is impossible to accurately grasp the position and depth of the skylight of the optical cable, and it is easy to cut the optical fiber in the optical cable and damage the optical cable.
