Anti-bite optical cable

Abstract

The invention discloses an anti-bite optical cable, which includes a sheath and a central sleeve arranged in the middle of the sheath. The central sleeve is filled with fiber paste, and a plurality of optical fibers are fixed in the central sleeve. On the outer wall of the sheath The upper sleeve is provided with a reinforcing tube, and a plurality of cavities are opened in the reinforcing tube, and the cavities are filled with capsaicin. The cavities are multiple groups distributed along the center of the reinforcing tube, and each group of cavities includes uniformly distributed Multiple in the circumferential direction of the reinforcing tube. There is no metal component in the strengthening tube, that is, under the multiple protection of the strengthening tube, sheath and central sleeve, the optical fiber located in the center will not be affected by external moisture, thereby ensuring the stability of the optical cable in the mountainous water-rich area Excellent working performance and prolong the service life of the optical cable.

Description

technical field [0001] The invention relates to the field of optical cable manufacturing, in particular to an anti-bite optical cable. Background technique [0002] In daily life, optical fibers are used for long-distance information transmission because the loss of light in optical fibers is much lower than that of electricity in wires. Most optical fibers must be covered by several layers of protective structures before use. The coated cable is called an optical cable. The protective layer and insulating layer on the outer layer of the optical fiber can prevent the surrounding environment from harming the optical fiber, such as water, fire, electric shock, etc. . [0003] In view of the requirements of the laying terrain of the optical cable, while meeting the transmission performance of the optical cable, the optical cable is also required to meet the applicability of the laying environment. For example, the laying of the optical cable in the mountainous area needs to me...

Problems solved by technology

In view of the prior art, the laying of optical cables in mountainous areas is easily damaged by rodents such as mice, resulting in damage to the sheath of the optical cable, and the metal support in the sheath is easily corroded by moisture, thereby shortening the service life of the optical cable. In the present invention, the central sleeve is firstly fixed in the middle of the sheath, and at the same time, the outer peripheral wall of the central sleeve is in close contact with the inner wall of the sheath. After a plurality of optical fibers are placed in the central sleeve, the central sleeve is filled with fiber paste , so that the inner wall of the sheath is fully supported, and then a layer of reinforced tube is sleeved on the outer wall of the sheath, and multiple cavities are opened in the reinforced tube, and the cavities are filled with capsaicin and other materials that can repel mice, and A plurality of cavities are arranged in multiple groups distributed along the center of the strengthening tube, and each group of cavities includes a plurality of cavities evenly distributed in the circumferential direction of the strengthening tube, that is, the processing of the optical cable is completed; and during the use of the present invention, When encountering rodent infestation, the rats will bite the reinforced tube until the cavity on the reinforced tube is broken, that is, capsaicin will be released immediately to prevent further biting by the rats. At the same time, no metal components are set in the reinforced tube, that is, Under the multiple protection of the strengthening tube, the sheath and the central sleeve, the optical fiber at the center will not be affected by external moisture, thereby ensuring the stable working performance of the optical cable in the mountainous water-rich area, prolonging the service life of the optical cable, and at the same time The gaps between multiple optical fibers in the central sleeve are filled with fiber paste, which can fix the sleeve and optical fibers to a certain extent and also play a role in mechanical buffering. Finally, the internal structure of the optical cable can be ensured to be compact and the cable’s reliability can be improved. The purpose of bending resistance and damage resistance
