Central-tube-type high-strength all-dielectric introductive optical fiber cable

Abstract

The invention discloses a central-tube-type high-strength all-dielectric introductive optical fiber cable. The central-tube-type high-strength all-dielectric introductive optical fiber cable comprises a loose sleeve in the center and a plurality of glass optical fibers inside he loose sleeve, wherein thixotropic water-proof fiber paste is filled between the loose sleeve and the glass optical fibers; a PE (polyethylene) sheath layer coats the outer surface of the loose sleeve; a plurality of water-proof aramid fibers are uniformly distributed between the loose sleeve and the PE sheath layer circumferentially; at least 2 enhanced glass fiber plastic rods are positioned on the two sides of the loose sleeve and are embedded into the PE sheath layer. The central-tube-type high-strength all-dielectric introductive optical fiber cable does not use the conventional metal material, so that the central-tube-type high-strength all-dielectric introductive optical fiber cable has a natural shielding effect on lightning or strong electricity and has an obvious lightning-proof effect, and potential safety hazards existing in the construction of an access network are eliminated.

Description

technical field [0001] The invention relates to a lead-in fiber optic cable, in particular to a central tube type high-strength all-dielectric lead-in fiber optic cable. Background technique [0002] With the continuous development of network technology, it has become an irreversible trend to implement optical input and copper output at the communication network access level. Optical fiber communication has the advantages of large communication capacity, high quality, stable performance, anti-electromagnetic interference, and strong confidentiality. It is a long-term solution for the development of broadband access. [0003] As the line medium of optical network construction, optical fiber cable is an indispensable part of optical access network (OAN) networking. It realizes the link between optical line terminal (OLT) and optical network unit (ONU), and completes the process from The conversion of the relevant signaling protocol between the service node interface (SNI) and...

AI Technical Summary

Problems solved by technology

In the actual use process, these kinds of optical fiber cables have exposed some problems: first, the optical fiber cables themselves have metal materials, and the optical fiber cables used for the access network are directly connected to the terminal. Bringing lightning into the room causes equipment loss or personal injury, which brings great potential safety hazards to users

Secondly, the wiring of the access network segment is dense, so the construction of optical fiber and cable is required to be fast and the later maintenance is easy. However, the outer diameter of the optical fiber and cable used in the traditional access network is relatively thick and heavy, and the difficulty of network wiring is relatively large.
