What is IEC 60793-2-93:2021?

IEC 60793-2-93:2021 is a technical standard published by the International Electrotechnical Commission (IEC). It provides the guidelines and specifications for the testing and characterization of optical fibres used in communications systems. This standard replaces the previous edition, IEC 60793-2-50:2016, and introduces new requirements and updates to ensure the reliability and performance of optical fibres. In this article, we will explore the key aspects of IEC 60793-2-93:2021 and its significance in the field of optical communication.

Understanding the Structure and Scope

The standard is organized into different parts, each addressing specific requirements and parameters related to optical fibre testing. IEC 60793-2-93:2021 specifically focuses on polarization-maintaining fibres. It covers various types of measurements, including geometrical, mechanical, and optical tests. The scope of this standard includes classification, qualification, environmental conditioning, and acceptance criteria for polarization-maintaining fibre products. By adhering to these guidelines, manufacturers can ensure the quality and consistency of their optical fibres.

Key Changes and Updates

IEC 60793-2-93:2021 introduces several significant changes compared to the previous edition. One notable update is the inclusion of stricter requirements for optical performance, such as attenuation and polarization-dependent loss. These updates reflect the industry's demand for higher data rates and increased signal stability. Additionally, the standard now includes specifications for single-polarization operation and improved polarization extinction ratio measurements. These changes aim to provide clearer guidelines for manufacturers and users when evaluating the performance of polarization-maintaining fibres.

Significance in Optical Communication

IEC 60793-2-93:2021 plays a vital role in ensuring the reliability and performance of optical communication systems. By complying with this standard, manufacturers can produce high-quality polarization-maintaining fibres that meet the demands of modern communication networks. The strict testing procedures outlined in the standard enable accurate characterization and comparison of different fibre products, facilitating informed decision-making for users. As optical communication continues to evolve, adherence to IEC 60793-2-93:2021 becomes increasingly critical to support the development of efficient and robust communication infrastructures.
