Overview
SIST EN 61300-1:2022/oprA2:2025 is an amendment to the international standard that specifies basic test and measurement procedures for fibre optic interconnecting devices and passive components. Published by the European Committee for Electrotechnical Standardization (CLC), this document is part of the IEC 61300 series, focusing on the general principles and guidance necessary for consistent and accurate testing in fibre optic communications. The amendment clarifies technical definitions and refines measurement methodologies relevant to quality assurance and performance validation of fibre optic devices.
Key Topics
Basic Test Procedures: EN IEC 61300-1 provides standardized methods to assess the performance and reliability of fibre optic interconnecting devices and passive components.
Encircled Flux Definition: The amendment refines the calculation and terminology used for encircled flux measurements, specifying the near-field intensity profile and radial positions more precisely to improve repeatability in modal power distribution testing.
Encircled Angular Flux: Updates clarify the far-field intensity profile parameters including angular and circular angles, along with the computational approaches using reference parameters r (radial distance) and d (distance to far-field pattern screen) following IEC 61300-3-53.
Measurement Techniques: Guidance on near-field and far-field intensity profiling helps ensure standardized optical characterization, essential for evaluating modal power distribution and angular emission properties of multimode fibre optic components.
Applications
Fibre Optic Installation and Testing: Ensures consistent measurement standards during installation, maintenance, and troubleshooting of fibre optic networks by technicians and engineers.
Quality Control in Manufacturing: Enables manufacturers of fibre optic connectors and passive components to verify compliance with international testing methods, supporting interoperability and reliability.
Research and Development: Facilitates the development of new fibre optic technologies by providing clear measurement frameworks to evaluate device performance characteristics.
Telecommunications and Data Centers: Assists in maintaining high-quality optical link performance critical to high-speed data transmission across telecommunication networks and data center interconnections.
Related Standards
IEC 61300 Series: Comprehensive guidelines on fibre optic interconnecting devices including detailed test methods for specific device categories and environmental conditions.
IEC 61300-3-53: Defines the measurement of encircled angular flux and is directly referenced in the amendment for computing far-field intensity profiles.
International Electrotechnical Commission (IEC) Standards: The SIST EN 61300-1:2022/oprA2:2025 aligns with global electro-technical guidelines ensuring harmonization across multinational markets.
By adopting SIST EN 61300-1:2022/oprA2:2025, stakeholders in optical communication systems enhance measurement accuracy, promote standardization in testing procedures, and optimize the performance and reliability of fibre optic interconnecting devices. This contributes to robust network infrastructures and facilitates international trade of compliant optical components.
