An easy-to-open skylight optical cable and its manufacturing method

Abstract

The invention relates to the field of optical fiber communication and its manufacture, and discloses an easy-to-open skylight optical cable, which includes an outer sheath and an inner layer. The outer sheath is hollow to form a storage cavity, and the storage cavity has a long end and a short end; The inner layer is housed in the housing cavity, and an optical fiber unit is arranged in the inner layer, and a gap is formed between the long end of the housing cavity and the outer wall of the inner layer, and the inner layer is covered by the The inner wall of the outer sheath is clamped at the short end; at the same time, the outer surface of the outer sheath is provided with at least one pair of marking lines extending along the length direction of the outer sheath cable, and a pair of marking lines The position is set so that on the cross section of the optical cable, the line between the two identification lines and every point on the surface of the outer sheath to the core of the optical cable passes through the gap. The invention also discloses a manufacturing method of the easy-open skylight optical cable. The invention can effectively improve the accuracy of cable stripping and avoid damage to optical fibers.

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...

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.
