Abstract

The invention discloses a high-strength folding-resistant indoor wiring optical cable which comprises a sheath cable body, reinforcing pieces and optical fibers. The sheath cable body is made of an environment-friendly halogen free flame retardant polyolefin material with high elasticity, has the characteristics of non-toxicity, environmental protection and flame retardance and is suitable to be laid and arranged indoors. Each reinforcing piece is manufactured by a method as follows: aramid fibers are used as a matrix; after being soaked in a polyester compound solution, the matrix is put in adie opening to be extruded, stretched and dried into a rod-shaped matrix of 0.5mm, and the tensile force of the matrix reaches more than 1,800mPa; a layer of reinforcing core which has a thickness of0.2mm and is made of a high-hardness folding-resistant flame retardant PVC material with high elasticity is thermally plastic-covered on the rod-shaped matrix; and the reinforcing pieces are symmetrically integrated in the sheath cable body in parallel. One or more optical fibers can be used in the indoor wiring optical cable, and each optical fiber has a diameter of 250 micrometers and is made of an insensitive optical fiber material which is easy to bend. By combining the use of the technology, the indoor wiring optical cable with a specification of 2*3mm realizes the practical effects of high strength and folding resistance.

Description

Technical field

[0001] The invention relates to an indoor wiring communication optical cable with an appearance size of 2×3MM, which is suitable for small-sized optical cables for FTTH terminal wiring. Background technique

[0002] With the rapid development of society, people are increasingly dependent on communication networks and information transmission. Communication networks are developing in the direction of large capacity and high density. Therefore, certain measures should be taken to protect the optical cable and strengthen the improvement of the optical cable to ensure the long-term smooth flow and reliability of the communication network.

[0003] The optical cable products currently on the market usually include two parts: the cable core and the sheath around the cable core. They often encounter two problems in use. Second, the low tensile force and poor anti-folding performance will also cause the optical fiber in the cable body to break and interrupt the tran...

Embodiment Construction

[0027] The high-strength anti-folding indoor wiring optical cable of the present invention is a small-sized (size 2×3MM) communication optical cable suitable for FTTH terminal wiring, and is especially suitable for indoor wiring in buildings, hotels, offices, etc. As shown in the figure, it includes: 1. a sheathed cable body, 2. a strengthening member, 201, a strengthening core, 3. an optical fiber, 4. a groove, and 5. an opening.

[0028] The sheath cable body 1 is made of an environmentally friendly flame-retardant polyolefin rodent-proof material that has a significant rat-bite-proof effect on rats after being tested by the "China Center for Disease Control and Prevention, Institute of Infectious Disease Prevention and Control". Features Non-toxic, environmentally friendly, flame-retardant, suitable for indoor laying and installation, and its elastic properties help the optical cable of the present invention quickly return to a straight state after being bent; and the sheath...
