Enhancement type rat-proof house wiring optical fiber cable

Abstract

The invention discloses a reinforced mouse-bite-proof indoor wiring optical cable, which comprises a sheath cable body, a reinforcing piece and optical fiber, wherein the sheath cable body is made of an environmental-protection-level halogen-free flame-retardant polyolefine material containing biological mouse-proof extractant; and an odor type mouse repelling batten is also arranged on the sheath cable body. Because the reinforced mouse-bite-proof indoor wiring optical cable adopts the double mouse repelling technology, mouse repelling and preventing effects are better enhanced, and the wiring optical cable has profound practical significance in improving the mouse-proof use reliability, guaranteeing the safe and reliable transmission of the communication network, and reducing the accident of communication network information interruption caused by mouse disaster.

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...

AI Technical Summary

Problems solved by technology

In the past, anti-rodent optical cable anti-rat methods mostly added anti-rat metal or non-metal protective sheaths on the periphery or middle layer of the optical cable core, such as Chinese patent CN03216625. There is a protective cover, the disadvantage is firstly that it increases the volume and weight of the optical cable, and the increased cost is not conducive to life; secondly, the increased protective cover does not have the ability to increase the anti-folding performance, but because of the increase in thickness, it reduces its elasticity and reduces Extended cable life

[0005] Furthermore, since the optical fiber in the optical cable is mainly composed of high-purity quartz glass, its physical properties of tensile strength and bending resistance are very fragile.

The commonly used indoor 2×3MM small-size indoor wiring optical cable, the main component of the core fiber is also high-purity quartz glass, with a diameter of only 0.25 mm, which is as thick as human hair, and its tensile and bending resistance The physical performance is also very fragile, and it is very easy to cause fiber breakage and damage when encountering the bite and pull of rats

In order to overcome the above shortcomings, the industry has made a lot of efforts and adopted many methods such as doping the surface of the optical cable with toxic agents, thickening the skin sheath layer, adding steel skin (armouring process) around the optical fiber, etc. to increase costs. It is a helpless move to increase the weight and volume of the cable body

These means and technological measures are obviously impossible to implement for small-sized indoor wiring cables with a cross-sectional area of ​​only 2×3mm.

Although adding toxic substances to the sheath layer of the optical cable can effectively kill rodents, it will also accidentally poison other animals such as squirrels and birds, which is not good for human health and environmental protection, especially when rodents are biting After being poisoned and killed by toxic cables, it will also cause short-circuit accidents in the computer room and other electrical circuits. At the same time, its rotting corpses and smell will also cause adverse effects on the surrounding environment.
