Advanced Quality Control Measures for Fiber Optics Cables
Dated back in 2015, the demand for optical fiber cable was about 280 million fiber kilometers globally. The demand has increased to 325 million fiber kilometers in 2018 and the figures will reach its new high in years to come. In a world where the consumers want value, there is no place for poor quality products or delayed deliverables. Let’s find out how the Quality Control inspection companies combine their industry-leading techniques to deliver high-quality fiber optic cables.
What is checked?
With the cutting-edge quality control services in Myanmar, Vietnam, and other Southeast Asian countries, you can check different types of cables like patch cords, pigtails, and cabinets.
How is it checked?
The fiber optic cables are checked on the basis of the following parameters:
- Connector types
- Colors
- Fiber coiling
- Plastic molding quality
- Insertion
- Attenuation
- Polarizing slot position
The inspection process includes:
- Visual testing: Visual testing involves identifying the defects at the very onset of production. With the use of tools like fiber optic tracing or pocket visual fault locator, it becomes much easier to detect if there’s any breakage or cracks from front to the rear end of the fiber. The visual testing also includes checking how clean the connector is. The process involves cleaning the connector with a wet cleaning technique followed with a dry clean method to make sure there’s no debris at the rear-face.
- Connector inspection technique: This is conducted with the help of a fiberscope to inspect the optical fiber components and ensure all of them are rightly fixed.
- Chemical composition checks: QC inspection laboratories look under the hood to verify the chemical composition to achieve optimal ratios. This is important to determine the co-efficiency of expansion, index of refraction, glass purity, and other relevant factors.
- Power measurement: This is one of the most important procedures of optical fiber cable QC process. The power is measured with the help of power meters to check the proportion of power is just right and not too low or high.
- Gas composition checks: During the initial production process, the inspectors check if the gas composition and the flow rate is accurate. They also ensure fiber optic devices like valves, pipes, and tubes do not corrode when it comes into contact with the gas.
- Chemical deposition testing: This is a heating and rotation process where a hollow cylinder is used to create the preform and is scalded at the right temperature. The process involves continuous rotation of the cylinder to ensure the chemicals are uniformly deposited.
