ADSS (All-Dielectric Self-Supporting) optical cable is a type of optical fiber cable that is designed to be used in overhead power line installations. It is an all-dielectric cable, meaning that it contains no metallic components, and it is designed to be self-supporting, which means that it can be installed without the need for a separate messenger wire. In this article, we will discuss the structure and characteristics of ADSS optical cable.

Structure of ADSS Optical Cable

ADSS optical cable consists of three main components: the optical fiber, the strength members, and the outer jacket.

Optical Fiber

The optical fiber is the most important component of the ADSS cable. It carries the light signals that are used for data transmission. The fiber is typically made of silica and has a diameter of 125 micrometers. The fiber is protected by a buffer coating, which is usually made of acrylate.

Strength Members

The strength members provide mechanical support to the ADSS cable. They are made of a high-strength material, such as aramid fibers or fiberglass. The strength members are designed to resist the tensile forces that are generated by the weight of the cable and the wind load.

Outer Jacket

The outer jacket provides additional protection to the ADSS cable. It is usually made of a polymer material, such as polyethylene or polyamide. The outer jacket is designed to protect the cable from environmental factors, such as moisture, UV radiation, and temperature variations.

Characteristics of ADSS Optical Cable

Self-Supporting

One of the most significant characteristics of ADSS optical cable is its self-supporting design. The cable is designed to be hung directly on the overhead power lines without the need for a separate messenger wire. This makes the installation process much faster and more cost-effective compared to other types of optical cables.

High Tensile Strength

ADSS optical cable is designed to withstand high tensile forces. The strength members are made of high-strength materials, and the cable is designed to resist the weight of the cable and the wind load. This makes the cable suitable for use in areas where there are high wind speeds or where the cable may be subjected to a significant amount of tension.

All-Dielectric

ADSS optical cable is an all-dielectric cable, meaning that it contains no metallic components. This makes it suitable for use in areas where there are high-voltage power lines. The lack of metallic components reduces the risk of electrical interference and eliminates the need for grounding.

Low Attenuation

ADSS optical cable has low attenuation, which means that the signal loss over distance is minimal. This makes the cable suitable for use in long-distance data transmission applications, such as telecommunications networks and high-speed internet connections.

Resistance to Environmental Factors

ADSS optical cable is designed to be resistant to environmental factors, such as moisture, UV radiation, and temperature variations. The outer jacket provides additional protection to the cable and helps to ensure that it remains functional even in harsh weather conditions.

Easy Installation

ADSS optical cable is relatively easy to install. The cable is designed to be self-supporting, which means that it can be installed without the need for additional hardware. This makes the installation process faster and more cost-effective compared to other types of optical cables.

Low Maintenance

ADSS optical cable requires minimal maintenance. The lack of metallic components eliminates the need for grounding, and the cable is designed to be resistant to environmental factors. This reduces the risk of cable failure and helps to ensure that the cable remains functional for an extended period.

In conclusion, ADSS optical cable is a type of optical fiber cable that is designed to be used in overhead power line installations.
