All-dielectric beam tube glass fiber band nylon anti-lighting, rat proof and anti-termite optical cable and manufacture method

Abstract

The present invention discloses an all-dielectric beam tube glass fiber band nylon anti-lighting, rat proof and anti-termite optical cable. The all-dielectric beam tube glass fiber band nylon anti-lighting, rat proof and anti-termite optical cable comprises at least one optical fiber (1), a loose tube (3), a glass fiber band (4), an inner sheath (5) and a nylon outer sheath (6); the optical fiber (1) is arranged in the loose tube (3), and casing fillers (2) are filled between the optical fiber (1) and the loose tube (3); a nonmetal reinforce (4), the inner sheath (5) and the nylon outer sheath (6) coat the loose tube in order, and a water-blocking yarn (7) is arranged between the loose tube (3) and the glass fiber band (4). An all-dielectric structure is employed, good shielding is provided for the thunder and the heavy current, and the safety and the practicality are very high.

Description

Technical field [0001] The invention relates to the technical field of optical cables, in particular to a full-dielectric bundle tube type glass fiber tape nylon lightning-proof, mouse-proof and ant-proof optical cable and a manufacturing method. Background technique [0002] With the continuous development of optical network technology, it has become an irreversible trend to implement optical in and copper out at the communication network access level. Due to the particularity of the installation environment of the optical fiber cable for the access network, due to poor grounding, the optical cable introduces lightning and damages the communication. The time of the device happens from time to time. Although the traditional non-metallic optical cable is also a full medium, it does not have the function of preventing rats and ants. It often happens that the optical cable is damaged by several bites. The optical cable is heavier and has a large outer diameter, which is convenient f...

AI Technical Summary

Problems solved by technology

Although the traditional non-metallic optical cable is also full-dielectric, it does not have the function of preventing rodents and termites. The phenomenon of several bites and damage to the optical cable often occurs, and the optical cable is heavy and has a large outer diameter. It is also convenient for construction and has potential safety hazards.
