FBR-ADSS-48C-8C6T-2KM

The cable has been designed, manufactured, and tested in accordance with standards.

ADSS (All-Dielectric Self-Supporting) is a type of fiber optic cable, particularly popular for overhead installations due to its ability to support its own weight without additional metal support.

ADSS Fiber Optic Cable Working Tension

Working tension, also known as specific tension, is the maximum tension the cable is subjected to. The ADSS optical fiber can withstand the design load over an effective usage life. Fiber optic cables can withstand short-term excessive loads, and fiber typically can withstand a tension of more than 60% of its breaking strength. When the tension in the fiber is less than 0.5% (for central tubes) and 0.35% (for multi-layer tubes), additional fiber attenuation may occur, but the fiber should return to normal when the tension is removed.

The correct operating voltage ensures the reliable operation of ADSS cables over their usage life. Generally, the length of the fiber optic cable section is between 50 and 100 meters, which is related to the number of cores and the weight of the cable; the heavier the cable, the shorter the section length. The locking distance is not directly related to the pulling force, and a locking distance of 100 meters can be achieved with a pulling force of 3 kN, but it is more suitable for distances of 600 meters. Generally, an ADSS fiber optic cable with a working tension of 24 kN has a length of approximately 300 to 400 meters.

ADSS Fiber Optic Cable Nominal Tensile Strength

The nominal tensile strength of the fiber optic cable, also known as the ultimate tensile strength or breaking strength, is the calculated value of the resistance of the carrying section (usually bent) of the cable. Any fiber breakage should be less than 95%. This parameter is optional because it is related to many control variables such as tower resistance, pulling connections, and seismic measurements.

Even with a large amount of yarn used in cable production, the relationship between the measured tensile strength (MAT) and the nominal tensile strength (RTS) is not appropriate if the current fiber deformation range is small. Generally, MAT is about 40% of RTS.

ADSS Fiber Optic Cable Maximum Allowable Tension

The maximum allowable tension of ADSS is theoretically calculated using weather conditions under which the cable is subjected to full load. The fiber deformation should be ≤ 0.05% (for lamine-tipped cables) and ≤ 0.1% (for central tube cables) when the tension is applied without causing additional attenuation.

This means that the tension is within the control value of the remaining length of the fiber. From this, the allowable usage distance of the fiber optic cable can be calculated based on the parameters, weather conditions, and the fall-off control curve. Therefore, the MAT calculation is important for the calculation of the weathering section of aerial fiber optic cables and the characterization of the ADSS cable's tension and deformation properties.

ADSS Fiber Optic Cable Average Annual Tension

The average annual tension of the fiber optic cable, without wind load, freezing, and at average annual temperature, is the tension the cable is subjected to in theoretical calculations. This can be considered the average tension of ADSS over a long-term operation. Generally, the average annual tension is 16% to 25% of the nominal tensile strength. Under this tension, the fiber should not experience additional deformation or attenuation, providing a very stable operation.

The average annual tension is also an important parameter for the wear and aging of fiber optic cables. Decisions regarding the vibration protection design of fiber optic cables can be made based on this value.

How to Choose the Right ADSS Cables?

To ensure optimal performance in your telecommunication network, selecting the right ADSS fiber optic cables is very important. Some important steps to consider when selecting ADSS cables are:

• Determine Your Loading Requirements

Before selecting an ADSS cable, it is important to understand the specific charging needs of your network. This includes the section length, the required number of cores, the expected maximum load, and local weather conditions. The more cores and the higher the load you need, the higher the nominal tensile strength of the ADSS fiber optic cable you may need to select.

• Consider the Weather Conditions

The weather conditions in your communication area are very important. If your region experiences severe winds, freezing, or extreme temperature changes, you should select an ADSS cable designed to withstand these specific conditions. The allowed maximum tension should be sufficient to withstand the tensions caused by these climatic factors.

• Evaluate Durability and Lifespan

The durability and lifespan of the cable are very important for a long-term investment. Ensure that the ADSS fiber optic cable is designed to have a long lifespan and meets your durability expectations by checking the specifications of the fiber optic manufacturer.

6.1 Cable Bending Radius

This measures how much the cable can be bent without damaging the cable or causing signal loss.

1. Static (Fixed): The bending limit allowed when the cable installation is completed and fixed.

2. Dynamic (Moving): The bending limit that must be adhered to when the cable is being pulled or installed (when in motion). Since fibers are more sensitive when under tension, this value is twice as high.
