OPGW vs. ADSS: Understanding the Differences Between Fiber Optic Cable Types for Power Transmission Lines
Difference Between OPGW Fiber Optic Cable and ADSS Fiber Optic Cable
OPGW and ADSS fiber optic cables are both types of outdoor fiber optic cables, which are used to transmit data over long distances. These cables are made up of extremely thin strands of glass or plastic, known as optical fibers, which are encased in the protective sheathing. The fibers are arranged in a bundle, called a cable core, which is then surrounded by additional layers of protective material to create the final cable.
While OPGW and ADSS fiber optic cables may appear similar at first glance. There are some key differences between the two that make them suitable for different applications and environments. Understanding these differences is important for choosing the right type of cable for a specific application.
Installation Method One of the main differences between OPGW and ADSS fiber optic cables is the way they are installed. OPGW fiber optic cable is installed on overhead transmission lines, while ADSS fiber optic cable is installed on the side of transmission towers. This means that OPGW fiber optic cable is subject to different environmental factors and physical stresses than ADSS fiber optic cable.
Type of Protective Sheath Another key difference between OPGW and ADSS fiber optic cables is the type of protective sheathing they use. OPGW fiber optic cable is encased in a layer of metal, typically aluminum or steel, which provides additional strength and protection. This metal sheathing also serves as a conductor, allowing the cable to function as a ground wire for the transmission line. ADSS fiber optic cable, on the other hand, is typically encased in a layer of aramid yarn, which provides strength and protection without conducting electricity.
Difference of Design The design of OPGW and ADSS fiber optic cables is also different. OPGW fiber optic cable is typically designed with a central tube, called the loose tube, which is filled with optical fibers. The loose tube is surrounded by a layer of water-blocking gel, which helps to protect the fibers from moisture. The cable is then surrounded by additional layers of protective material, such as aramid yarn, to provide additional strength and protection. ADSS fiber optic cable, on the other hand, typically uses a tight buffer design, where each fiber is encased in a layer of protective material, called a buffer coating. This provides additional protection for the fibers, making them more resistant to damage from bending or crushing.
Temperature Rating Another key difference between OPGW and ADSS fiber optic cables is their temperature rating. OPGW fiber optic cable is typically designed to operate at temperatures ranging from -40°C to 85°C, while ADSS fiber optic cable is typically designed to operate at temperatures ranging from -40°C to 70°C. This means that OPGW fiber optic cable is better suited for use in extreme temperature environments, while ADSS fiber optic cable is more suitable for use in milder temperature conditions.
Transmission Performance In terms of transmission performance, OPGW and ADSS fiber optic cables are generally similar. Both types of cables can transmit data at high speeds over long distances, without the need for signal amplification. They are also immune to electromagnetic interference, making them ideal for use in environments with high levels of electromagnetic interference.
One of the main advantages of OPGW fiber optic cable is its ability to function as a ground wire for the transmission line. This means that it can provide both data transmission and grounding capabilities, which can simplify the design of the transmission line and reduce the amount of cable required. ADSS fiber optic cable, on the other hand, does not conduct electricity, so it cannot be used as a ground wire.

What is armored optical cable? Structure, type and application of armored optical cable
Armored fiber optic cable is the same as armored cable. Armored Fiber Optic Cable, as the name suggests, is a kind of fiber optic cable wrapped with a layer of protective "armor".
Structure of armored optical cable
In the design of armored optical cable, the outer tube can protect the cable from solvents and abrasion. Usually the outer sleeve is made of plastic, such as polyethylene. Between the outer sleeve and the inner sheath is armor, which is difficult to cut, bite and burn, such as steel strips and aluminum foil. The armor material can also prevent the optical cable from stretching during the cable laying process. Then there is the sheath stripping rope. Usually, the sheath stripping rope is directly under the armor and the inner sheath, which can help strip the sheath when splicing the optical cable to the connector or terminal. The inner sheath is a protective and flame-retardant material that can support the inner optical cable harness. The internal optical cable harness includes strengthening members, fillers and other structures to support the optical cable internally. Usually there is a central strengthening element to support the entire fiber optic cable. In simple terms, in an armored cable, the buffer pipe is surrounded by a layer of aramid yarn, a layer of polyethylene sheath, and a layer of corrugated steel armor. In this type, there is also a black medium-density polyethylene sheath with a sheathed peeling rope.
Type of armored cable Armored optical cables are generally divided into indoor and outdoor types.
There are three types available: double armored, single armored, and unarmored.
Double-layer armored cables are used in shallow coastal waters, and non-armored cables are used in most cases of submarine cables. Single-layer armored cables are used for other occasions beyond these extreme conditions.
Features High tensile strength
High compressive strength against improper distortion
Simple structure to prevent bending damage
Save maintenance costs
Suitable for harsh environments and can prevent human damage
Application Armored optical cables are used in directly buried external equipment applications. In these applications, strong optical cables are required, and they need to be able to resist the bite of rodents and other animals.
This kind of optical cable has good anti-extrusion performance, which is very necessary for direct landfill. Use directly buried optical cables in areas where rodents are more harmful. Normally, there is a metal armor between the two bushings to prevent rodents from biting through the bushing.
Another application area of armored fiber optic cables is in data centers, where the fiber optic cables are installed below the ground, so it is possible that the fiber optic cables may be damaged due to the extrusion of the floor. Because the armored optical cable is conductive, it must be well grounded using an appropriate method.
The armored optical cable used in outdoor applications is designed with a typical loose tube structure so that it can be directly buried in the ground.
Under normal circumstances, the armor is corrugated aluminum tape, and the outer layer is covered with a polyethylene bushing. This combination of outer sleeve and armor can protect the fiber optic cable from animal damage, and will not be damaged during the installation process of direct landfill.
The armored optical cable used in indoor applications is characterized by tightly buffered optical fibers or loose buffered optical fibers, strengthening members and internal bushings, and is covered with spirally wrapped interlocks on the outside metal tape armor.
