EN 61300-2-9:2017/prA1:2025

Overview

EN 61300-2-9:2017/prA1:2025 is the latest amendment to the international standard governing basic test and measurement procedures for fibre optic interconnecting devices and passive components. Focusing specifically on shock testing, this amendment refines testing parameters to better assess the mechanical robustness of optical components used in fibre optic communication networks. Published by CLC and aligned with IEC technical specifications, this standard amendment ensures that manufacturers and testing laboratories apply consistent, reliable methods for shock resistance evaluation.

Key Topics

• Shock Testing Procedures: The amendment details updated parameters for shock testing, including waveform, acceleration, duration, number of shocks, and axes of impact. Tests use a half-sinusoidal waveform to simulate mechanical shocks.

• Component Mass Categories: The update distinguishes different shock severity levels based on the mass of the fibre optic component or module:

  • ≤ 0.125 kg

  • 0.125 kg and ≤ 0.225 kg

  • 0.225 kg and ≤ 1 kg

• Updated Shock Parameters:

  • For components ≤ 0.125 kg: acceleration of 5000 m/s² with 1 ms duration.
  • For modules > 0.125 kg and ≤ 0.225 kg: acceleration of 2000 m/s² with 6 ms duration.
  • For modules > 0.225 kg and ≤ 1 kg: acceleration of 500 m/s² with 11 ms duration.

• Testing Directions and Axes: Shock tests are performed along three mutually perpendicular axes, with two opposite directions per axis, ensuring comprehensive mechanical stress evaluation.

• Specific Testing for Fibre Management Systems and Protective Housings: Defined shock severity conditions for fibre management enclosures, closures, wall outlets, and hardened connectors are specified to ensure durability under actual deployment scenarios.

Applications

• Fibre Optic Device Manufacturers: Use the updated test methods to validate mechanical shock resistance of interconnecting devices and passive components prior to market release.

• Quality Assurance Testing: Sensors, modules, and protective housings undergo rigorous shock testing based on these parameters to maintain product reliability during shipping, installation, and operation.

• Telecommunication Infrastructure: Ensures that fibre optic components deployed in network distribution frames, closures, and wall outlets withstand mechanical impacts without performance degradation.

• Testing Laboratories: Apply the standardized procedures for repeatable and accepted compliance testing, supporting certification and regulatory requirements.

Related Standards

• IEC TS 62538: Defines component and module classifications referenced for mass categories in shock tests.

• IEC 61753-1, Edition 3: Details definitions and qualifications for protective housings used in fibre optic networks, complementing EN 61300-2-9 shock testing criteria.

• IEC 61300 Series: Covers a broad range of test and measurement procedures for fibre optic interconnecting devices and passive components, providing comprehensive guidelines beyond shock tests.
