What is IEC 60793-2-99:2021?

IEC 60793-2-99:2021 is an international standard that defines the requirements for optical fiber specifications in terms of reliability and performance. This technical article aims to provide an easy-to-understand explanation of the key aspects of this standard.

Fiber Types

The standard classifies optical fibers into different types, known as categories A, B, and C. Each category specifies certain characteristics that the fiber must meet. For example, Category A fibers are designed for use in indoor environments and have tighter requirements for transmission loss and resistance to bending. On the other hand, Category C fibers are suitable for outdoor installations and have higher resistance to environmental factors such as moisture and temperature fluctuations.

The specification also includes information about the core size, cladding diameter, and numerical aperture of the fibers. These parameters determine the light-carrying capacity and the efficiency of signal transmission through the fibers.

Mechanical and Environmental Performance

In addition to optical performance, IEC 60793-2-99:2021 covers mechanical and environmental properties of optical fibers. The standard defines various tests to evaluate factors such as tensile strength, crush resistance, and flexibility. These tests ensure that the fibers can withstand normal handling during installation and operation.

The standard also addresses the influence of external factors on fiber performance. It provides guidelines for assessing the effects of temperature, humidity, and chemical exposure on the fibers. This information helps users select the appropriate type of fiber for specific operating conditions.

Application Considerations

IEC 60793-2-99:2021 takes into account the diverse applications of optical fibers. Whether it's telecommunications, data centers, or industrial use, the standard provides guidance on selecting a fiber type that meets the specific requirements of each application.

For example, in high-speed data transmission applications, fibers with low dispersion and attenuation are preferred. On the other hand, fibers used in harsh environments need to have superior mechanical strength and resistance to adverse conditions.

The standard also emphasizes the importance of documentation and labeling. It requires manufacturers to provide clear information about the fiber's specifications, so that users can easily identify and select the appropriate fiber for their needs.

In conclusion, IEC 60793-2-99:2021 is a comprehensive international standard that defines the requirements for optical fibers. By categorizing fibers based on their characteristics and specifying performance tests, it enables users to make informed decisions regarding fiber selection for various applications. This standard plays a crucial role in ensuring the reliability and performance of optical fiber networks around the world.
