What is IEC 60793-2-108:2021?

The International Electrotechnical Commission (IEC) is a globally recognized organization that establishes and publishes standards for various industries. One of the widely used standards in the fiber optic industry is IEC 60793-2-108:2021. This standard defines the optical fibers used in telecommunication networks and provides essential specifications for their performance characteristics.

Background and Scope

IEC 60793-2-108:2021 is part of a series of standards that specifically focuses on single-mode optical fibers. It sets out the requirements for Category B1.1 fibers, which are designed for long-haul communication systems with high-bit-rate transmission capacity. These fibers have specific attributes that make them suitable for use in demanding applications where reliable and high-speed data transmission is critical.

Key Parameters and Performance

This standard specifies several key parameters and performance characteristics for Category B1.1 fibers. One of the crucial parameters is the attenuation, which measures the loss of optical power as it propagates through the fiber. IEC 60793-2-108:2021 sets strict limits for attenuation to ensure low signal degradation and efficient transmission over long distances.

Another important factor defined by this standard is the chromatic dispersion. Chromatic dispersion refers to the spreading of different wavelengths of light in a fiber, leading to signal distortion. To guarantee reliable data transmission, IEC 60793-2-108:2021 provides maximum allowable limits for chromatic dispersion, ensuring minimal signal distortion and maintaining signal integrity.

Certification and Compliance

To demonstrate compliance with IEC 60793-2-108:2021, fiber optic manufacturers must undergo rigorous testing and certification processes. These tests evaluate various performance parameters, such as attenuation, chromatic dispersion, and geometrical characteristics. Compliance ensures that the manufactured fibers meet the required standards, ensuring interoperability and compatibility in telecommunication networks.

The certification process usually involves independent third-party testing laboratories that validate the performance of the fibers. Manufacturers can then provide a compliance certificate to assure customers that their products conform to the specifications outlined in IEC 60793-2-108:2021.
