Abstract

The utility model relates to a pipeline covered-wire introduction fireproof composite optical cable for communication, which is applicable to the outside of a building and the inside of the building and comprises optical fibers, aramid fiber bars, low smoke zero halogen jackets, a copper wire, water-blocking tapes, aluminum-plastic composite tapes and polyethylene (PE) jackets. The optical fibers and the aramid fiber bars are arranged in arrays, and the outer-protection low smoke zero halogen jackets serve as covered-wire cables. Outside protection cushion layers of the copper wire are symmetrically filled inside the covered-wire cables on two sides, and the reinforcement water-blocking tapes, the water-blocking layer aluminum-plastic composite tapes and the PE jackest are sequentially wrapped outside the outside protection cushion layers of the copper wire. The pipeline covered-wire introduction fireproof composite optical cable for communication not only realizes transmission of the optical signals, but also resolves the problem of equipment electricity utilization, and simultaneously effectively improves fireproof performance of the pipeline covered-wire cables.

Description

Duct sheath lead into composite optical cable

technical field

The utility model relates to the technical field of electric cables, in particular it is a kind of composite optical cable led by pipeline leather wires for communication.

Background technique

In recent years, my country's optical fiber access market has shown a good momentum of development, and optical fiber access has become a hot spot in the field of optical communications. In the optical fiber access project, the indoor wiring close to the user is the most complicated link. Because the traditional outdoor optical cable has a large outer diameter and high hardness, usually contains oil and is not flame-retardant, these characteristics make the outdoor optical cable unsuitable for use in buildings; while the traditional indoor optical cable has the characteristics of no water resistance, no UV aging resistance, and insufficient strength. The lack of outdoor optical cable construction requirements and other aspects is not suitable for the connection from outside to inside the building. Aiming at such a situation, the pipe sheath line is introduced into the composite optical cable, which not only solves the transmission of optical signals, but also solves the problem of power consumption of equipment.

Contents of the invention

The purpose of the utility model is to provide a conduit sheath line for communication leading into a composite optical cable. It not only solves the transmission of optical signals, but also solves the problem of equipment power consumption. It includes: optical fiber, aromatic wheel rod, low-smoke halogen-free sheath, copper wire, water-blocking tape, aluminum-plastic composite tape, PE sheath, and is characterized in that: optical fiber and aromatic wheel rod are arranged, covered with low-smoke halogen-free sheath Wrapped, copper wires are filled on both sides of the cable, and the reinforced layer water-blocking tape is outsourced, the reinforced layer water-blocking tape is covered with a water-blocking aluminum-plastic composite tape, and the outermost layer is protected by a low-smoke, halogen-free, flame-retardant sheath. The copper conductor jacket has a copper conductor underlayment. The reinforcement layer is a water-blocking tape. The water blocking layer is aluminum-plastic composite tape.

The advantages of the present invention are:

1. The optical cable production process is simple, no grease filling, easy to connect and install;

2. The use of aluminum-plastic composite tape longitudinally wrapped with water-blocking tape will protect the optical fiber well even when the humidity in the use environment is heavy, and the effect of water-blocking and moisture-proof is good;

3. It can effectively solve the problems of bandwidth access, equipment power consumption, and signal transmission;

4. It is suitable for pipeline construction. The sheath made of low-smoke, halogen-free and flame-retardant sheath material is tougher and wear-resistant than conventional leather cables, ensuring that indoor cables can also protect optical fibers well during construction in pipelines, reducing construction costs. Even if the environmental conditions are not good, it cannot affect its transmission performance;

5. Has a certain ability to resist the bite of rodents;

6. Good insulation;

7. The connection between the access port and the optical cable is protected by a metal tube, which will not break it during use.
