Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber ribbon cables, and in particular relates to a central spiral enhanced compact optical fiber ribbon cable. Background Art

[0002] Optical cable is a communication cable assembly manufactured to meet optical, mechanical or environmental performance specifications. It mainly uses one or more optical fibers placed in a sheath as a transmission medium and can be used alone or in groups. Optical cable is mainly composed of optical fiber, plastic protective sleeve and plastic sheath.

[0003] Fiber optic ribbon cable, also known as ribbon cable, is a special optical cable structure. The internal optical fibers are arranged in the form of fiber optic ribbons. The fiber optic ribbon is a thin flat ribbon formed by solidifying 4 to 24 optical fibers arranged in parallel.

[0004] At present, optical fiber ribbons and optical cables are usually protected by fiber grease and loose tubes. This structural method has the following defects:

[0005] 1. The optical fiber ribbons at the stacking corners of the optical fiber ribbons directly touch the inner wall of the sleeve, causing increased attenuation;

[0006] 2. Low lateral pressure resistance, high cost, inconvenient fiber paste handling, and fiber paste is easy to drip when laid vertically, causing pollution and product failure;

[0007] 3. It is not easy to carry out the connection operation. Utility Model Content

[0008] The utility model aims to provide a central spiral reinforced compact optical fiber ribbon cable to solve the problems of reduced cable performance and poor lateral pressure resistance due to structural defects in existing optical fiber ribbon cables.

[0009] The technical solution adopted by the utility model is as follows:

[0010] A central spiral reinforced compact optical fiber ribbon cable comprises a cross metal reinforcement member, which is in a spiral structure along the length direction, a foam water-blocking tape is arranged on the cross metal reinforcement member, a sheath is arranged on the foam water-blocking tape, four right-angle installation areas are formed on two adjacent sides of the cross metal reinforcement member, and the right-angle installation areas are provided with optical fiber ribbons.

[0011] Furthermore, the optical fiber ribbon is a square laminated structure.

[0012] Furthermore, a square sleeve is sleeved on the optical fiber ribbon.

[0013] Furthermore, the foam side of the foam water-blocking tape faces one side of the cross metal reinforcement.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0015] 1. In the utility model, the cross metal reinforcement is in a spiral structure along the length direction, and the two sides form a right angle. Compared with the traditional loose tube + fiber paste method, the storage of the optical fiber ribbon is more stable, and the problem of increased attenuation caused by the optical fiber ribbon on the corner of the optical fiber ribbon stack directly touching the inner wall of the tube is avoided. At the same time, the structure does not require grease, and the connection operation is convenient. The whole structure is more compact than the traditional optical fiber ribbon tube method, reduces the outer diameter of the optical cable, improves the optical fiber density, and is a fully dry structure. Compared with the current conventional optical fiber ribbon cables, it has cost advantages. BRIEF DESCRIPTION OF THE DRAWINGS
