Both OPGW optical cable and ADSS optical cable are outdoor optical cables for long-distance data transmission. These cables consist of very thin strands of glass or plastic, called optical fibers, that are enclosed in a protective sheath. Optical fibers are bundled together to form a cable core, and then additional protective material is added on the outside to form the final cable.
Although OPGW and ADSS cables may look similar in appearance, there are some key differences between them that make them suitable for different applications and environments. Understanding these differences is important in selecting the appropriate fiber optic cable for a particular application.
One of the main differences between OPGW optical cable and ADSS optical cable is the installation method. OPGW optical cables are installed on overhead transmission lines, while ADSS optical cables are installed on the side of transmission towers. This means that OPGW optical cables and ADSS optical cables face different environmental factors and physical stresses.
Another key difference between OPGW and ADSS cables is the type of protective jacket used. OPGW cables are sheathed in a metal jacket, usually aluminum or steel, for extra strength and protection. This metallic sheath also acts as a conductor, enabling the cable to work as a ground wire for transmission lines. ADSS cables, on the other hand, are usually sheathed in a layer of aramid yarn, which provides strength and protection, but is not conductive.
The design of OPGW optical cable and ADSS optical cable is also different. OPGW optical cables are usually designed with a central tube, that is, a loose tube, which is filled with optical fibers. The loose tube is covered with waterproof glue to help protect the fiber from moisture. There is additional protective material on the outside of the cable, such as aramid yarn, for extra strength and protection. ADSS cables, on the other hand, typically use a tightly buffered design, with each fiber wrapped in a protective material called a buffer coating. This design provides additional fiber protection, making it more resistant to bending and crushing.
Another important difference between OPGW and ADSS cables is their temperature rating. OPGW cables are typically designed for temperatures ranging from -40°C to 85°C, while ADSS cables are typically designed for temperatures ranging from -40°C to 70°C. This means that OPGW cables are more suitable for extreme temperature environments, while ADSS cables are more suitable for milder conditions.
In terms of transmission performance, OPGW optical cables and ADSS optical cables are generally similar. Both types of fiber optic cables are capable of transmitting data at high speeds over long distances without signal amplification. They are also immune to EMI, making them ideal for high EMI environments.
A major advantage of OPGW fiber optic cable is its ability to work as a ground wire for power transmission lines. This means it can provide data transmission and grounding functions, simplifying the design of power transmission lines and reducing the amount of fiber optic cables required. However, ADSS fiber optic cables are not conductive and cannot be used as ground wires.
