Overview
EN IEC 61280-4-1:2019/A1:2022 is a European Standard that specifies test procedures for fibre-optic communication subsystems, focusing specifically on installed cabling plant multimode attenuation measurement. This standard serves as an amendment to EN IEC 61280-4-1:2019 and incorporates important technical updates related to measurement accuracy, test cord specifications, and testing methods.
Published and maintained by CLC (European Committee for Electrotechnical Standardization), this updated document ensures harmonized and reliable practices for measuring signal attenuation in installed multimode fibre optic cabling plants. Accurate attenuation measurement is critical for ensuring the performance and reliability of fibre optic communication networks, especially in multimode fibre environments.
Key Topics
This standard addresses essential aspects for multimode attenuation measurements, including:
Test Cord Specifications
- Launch cords, receive cords, and substitution cords are defined by length (2 m to 10 m) and connector grades.
- Test cords for LSPM (Loss Subsystem Performance Measurement) may contain A1-OMxa or A1-OMxb fibres (BIMMF - Bend Insensitive Multimode Fibre), reflecting recent advances in fibre technology.
- Substitution cords must match length and fibre grade to maintain measurement consistency.
Measurement Procedures
- Detailed methodologies for assessing attenuation in installed multimode fibre optic cabling plants.
- Emphasis on proper connection and alignment to ensure accurate measurement of multimode signal loss.
- Adjustments to terminology such as replacing “attenuation” with “loss” for clarity in specific test contexts.
Connector and Fibre Performance Grades
- Requirements specify referencing either standard grade or reference grade connectors for test cords.
- Differentiation of fibre types in test cords, highlighting whether the fibre is bend-insensitive (OMxb) or conventional multimode fibre (OMxa).
Technical Amendments
- Updated recommendations on launch cords adapting to new fibre types and improved macrobend loss performance levels.
- Clarification of lengths and configurations for receive and substitution cords.
- Enhanced guidance supporting consistent test results and repeatability across different testing environments.
Applications
EN IEC 61280-4-1:2019/A1:2022 plays a vital role in the following areas:
Fibre-Optic Network Installation and Maintenance
Professionals use the standard to verify attenuation performance and ensure the quality of newly installed multimode fibre cabling before deployment.Telecommunications Infrastructure Testing
Network operators rely on these test procedures to maintain signal integrity and troubleshoot fibre optic faults within multimode cabling plants.Data Centers and Enterprise Networks
Provides essential guidelines to measure losses in short-run multimode fibre installations typical in data center environments, ensuring compliance with performance benchmarks.Manufacturing and Quality Assurance of Fibre Cables
Manufacturers and testers adopt the procedures to verify attenuation specifications and produce reliable cabling products compatible with market demands.
Related Standards
For comprehensive fibre optic system testing and installation, this standard is closely related to:
- IEC 61280 series - Other parts regarding different subsystems and fibre types in optical communications.
- ISO/IEC 14763-3 - Planning and installation of fibre optic cabling infrastructure.
- IEC 61300 series - Fibre optic interconnecting devices and passive components test procedures.
- EN IEC 60793-2-x and EN IEC 60794-x - Fibre optic cables and fibres specifications relevant to multimode fibres.
- CENELEC Internal Regulations - Governing the adoption and implementation of European Standards like EN IEC 61280-4-1.
Maintaining compliance with EN IEC 61280-4-1:2019/A1:2022 ensures accurate, repeatable, and standardized loss measurements critical to the design, deployment, and operation of multimode fibre optic communication systems. It supports telecommunications professionals in achieving robust performance metrics and enhancing the reliability of optical network infrastructures.
