The fast-paced and interconnected nature of our modern world relies heavily on fiber optic cables to establish dependable communication networks. To guarantee the smooth transmission of data, it becomes imperative to assess the quality and performance of these cables through the utilization of specialized intrument like a fibre optic cable testing.
These testing instruments are designed to evaluate the quality, durability, and tensile strength of fiber optic cables, safeguarding the integrity of telecommunications networks and data centers. In this blog post, we will explore the fundamentals and advantages of fiber optic cable testing, including how to effectively test a fiber optic cable.
Understanding Fiber Optic Cable Testing Equipment
Optical cable testing machines are specialized devices designed to test indoor optical cables. These machines can apply controlled tensile forces on the cables, allowing technicians to assess their tensile strength and durability. Additionally, optical cable testing machines feature an extensometer, which accurately measures the cable elongation when subjected to tension.
The primary purpose of these machines is to evaluate the performance and reliability of indoor optical cables under different levels of tension. By applying controlled tensile forces, technicians can assess how the cables withstand stress and determine their tensile strength. This information is vital for ensuring that the cables can endure the rigors of installation and operation without experiencing structural damage or signal loss.
The inclusion of an extensometer in optical cable testing machines is crucial for precise measurements of cable elongation. As tension is applied to the cable, the extensometer measures the changes in its length, providing valuable data on the cable’s flexibility and elasticity. This data helps technicians understand the cable’s behavior under tension and ensures it meets the necessary standards and specifications.
This instrument is also important to evaluate the cable’s tensile strength. The tensile strength of Fiber Optic Cables refers to the maximum amount of pulling force a cable can withstand without breaking or suffering permanent damage. Measuring and understanding the tensile strength of fiber optic cables is crucial for ensuring their durability and ability to withstand tension and stress during installation and operation.
Overall, optical cable testing machines play a pivotal role in evaluating indoor optical cables’ performance and tensile strength. By applying controlled forces and measuring cable elongation, technicians can ensure the cables’ reliability and durability, enabling seamless and uninterrupted data transmission in indoor environments.
Standard Testing Methods
The method used in the Optical Fiber Cable Tensile Testing Machine – Indoor Cable follows the IEC-60794-1-2 Method E1. The international standard governs this method and aims to measure the tensile strength of fiber optic cables.
The IEC standards are widely recognized as the best practices in the global fiber optic cable industry. Method E1 provides a standardized procedure for testing the tensile strength of fiber optic cables, ensuring consistent test results across various laboratories and testing locations. It also generates highly accurate data regarding the tensile strength of fiber optic cables, which is crucial for assessing the integrity and performance in various applications.
One of the advantages of this method is its strict documentation requirements, enabling users and fiber optic cable manufacturers to track test results precisely. This is essential for quality management and cable performance evaluation. As a part of an international standard, the E1 method is used by many companies and organizations worldwide, facilitating the comparison and exchange of information among stakeholders in the fiber optic cable industry.

How to Test a Fiber Optic Cable
Testing a fiber optic cable involves a series of steps and the use of appropriate testing equipments. Technicians must follow proper procedures to assess the cable’s performance accurately. The following steps can be followed to test a fiber optic cable based on the provided information.
. Setup and Preparation
- Wind the cable in the testing machine over appropriately sized sheaves.
- Ensure that the cable ends extend to reach the measuring instruments for accurate measurements.
- Concatenate a pre-determined number of fibers within the cable using fusion splicing. Typically, two sets of fibers are used: one for measuring attenuation change and the other for elongation monitoring.
2. Initial Measurements and Calibration
- Perform initial measurements and calibration to establish a baseline for comparison.
- This step ensures accurate and reliable test results.
3. Cable Tensioning
- Pull the cable at a specified rate until a pre-determined tension is applied.
- This tension level is determined based on the cable’s specifications and the desired testing parameters.
4. Tensioned Cable Resting
- Lay the cable to rest under tension according to detailed specifications.
- This allows for evaluating the cable’s behavior and performance under sustained tension.
5. Attenuation and Fiber Length Measurement
- Measure the attenuation, which refers to the loss of signal strength, at the specified tension level.
- This measurement helps identify any excessive signal loss that may affect the cable’s performance.
6. Characterization of Tensile Behavior
- Depending on the testing requirements, the process may involve several tensile levels to characterize the entire tensile behavior of the cable.
- Alternatively, the testing may be carried out only at the defined maximum allowed tension level.
By following these steps, technicians can effectively use Fibre Optic Cable Testing. The process involves winding the cable in the machine, concatenating fibers, performing initial measurements, applying tension, measuring attenuation and fiber length, and characterizing the cable’s tensile behavior. These tests ensure the cable’s performance, durability, and compliance with specified standards.
