Mouseproof optical cable

Abstract

The invention discloses a mouseproof optical cable which comprises a cable core, an outer sheath, and a soft armor layer. The outer sheath coats the cable core. The soft armor layer coats the outer sheath and is made of a PA12 material. The structure of the mouseproof optical cable is simple, the soft armor layer can effectively prevent the optical cable from being bitten, the integrity of the optical cable is ensured, the weight of the optical cable is not increased, and the production cost is effectively controlled.

Description

technical field

[0001] The invention relates to the technical field of optical fiber transmission, in particular to a mouse-proof optical cable. Background technique

[0002] At present, there are two ways to prevent rats from damaging optical cables in the market. One is chemical method, that is, mixing repellent into the outer sheath to prevent rats; the other is physical method, mainly through steel tape armoring, steel wire The armor uses the hardness of the metal to prevent rats from biting, and also adds glass yarn to the inside of the outer sheath to use the sharpness of the glass yarn after being bitten by rats to pierce the throat of rats to prevent rats. The method of adding repellent substances in the sheath material of the optical cable is mainly by adding strong irritating chemical substances such as capsicum, which has the advantages of low cost and little change in the structure of the optical cable. The environment is polluted, the personnel in the processin...

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] like figure 1 Shown, be the anti-rat optical cable in the present invention, comprise cable core, outer sheath 3 and soft armor layer 4, outer sheath 3 is coated on the cable core, soft armor layer 4 is coated on the outer sheath 3, soft armor The layer 4 is made of PA12, the thickness of the soft armor layer 4 is 0.1-0.5cm, and the outer sheath 3 is made of polyethylene.

[0019] The rodent-proof optical cable also includes a shielding layer 5, which is coated on the cable core and located between the cable core and the outer sheath 3, which can effectively play the role of ionization shielding and ensure that the optical fiber information transmission is not disturbed by the external environment. The shielding layer 5 is preferably an aluminum tape layer, which is low in price and light in weight, which reduces the weight of...
