Overview

SIST EN 61300-3-52:2014 is a critical European standard addressing fibre optic interconnecting devices and passive components. Specifically, it defines basic test and measurement procedures for measuring the guide hole and alignment pin deformation constant (CD) in 8-degree angled Physical Contact (PC) rectangular ferrule multi-fibre connectors using single mode fibres. This standard, based on IEC 61300-3-52:2014, provides a precise method for assessing deformation caused by mating forces in the alignment components of fibre optic connectors, ensuring optimal connector performance and reliability in telecommunications and data transmission networks.

Key Topics

  • Guide Hole and Alignment Pin Deformation Constant (CD):
    Measures the deformation at the guide hole and alignment pin interface under applied force, which impacts fibre alignment and connector insertion loss.

  • 8-Degree Angled PC Rectangular Ferrule:
    The standard focuses on multi-fibre connectors featuring an 8-degree angled PC ferrule design, which reduces back reflections in fibre optic links.

  • Measurement Procedure:
    The deformation constant is measured using a precision linear scale apparatus, applying controlled forces typically at 0.7 N per guide hole, simulating nominal mating conditions of 9.8 N total. Displacement readings quantify deformation and guide hole pin fit quality.

  • Test Conditions:
    Defined environmental and physical conditions include temperature (22.0 to 24.0 °C), relative humidity (50% ±10%), ferrule adhesion condition, and maximum pin diameter (0.6988 mm) ensuring repeatability and comparability of results.

  • Apparatus and Sample Preparation:
    Requires a high-resolution linear scale with 0.01 μm precision, force indicators, and gauge blocks with smooth, hard surfaces. MT ferrules are adhesively mounted on gauge blocks with alignment pins inserted under strict positional controls.

  • Data Analysis:
    Multiple measurements are repeated for accuracy, and deformation-force relationships are plotted to extract the constant CD from the graph’s fitting curve.

Applications

  • Connector Quality Control:
    EN 61300-3-52 is essential for manufacturers and testing laboratories verifying the mechanical integrity and alignment precision of fibre optic connectors, especially those designed with angled PC rectangular ferrules.

  • Design Verification and Development:
    Helps engineers optimize ferrule materials, geometry, and adhesive processes to minimize deformation and ensure consistent fibre alignment across mass-produced connectors.

  • Telecommunications Networks:
    Ensures that connectors used in high-speed single mode fibre optic networks meet stringent deformation standards, directly impacting signal integrity and system uptime.

  • Optical Component Standardization:
    Provides a uniform test method supporting interoperability and compliance across manufacturers, facilitating global supply chains and network deployments.

Related Standards

  • IEC 61754-7: Defines fibre optic connector interfaces for the MPO connector family, relevant due to similar multi-fibre ferrule designs.

  • IEC 61754-10: Covers optical interface standards for Mini-MPO connector families, where alignment and deformation constants also play significant roles.

  • IEC/PAS 61755-3-32: Specifies optical interfaces for 8-degree angled PC rectangular ferrules with single mode fibres, complementing mechanical deformation measurement with optical performance standards.

Conclusion

SIST EN 61300-3-52:2014 provides a robust, precise methodology for measuring the deformation constant of guide holes and alignment pins in multi-fibre 8-degree angled PC rectangular ferrule connectors. By standardizing this test, it ensures consistent connector performance, aids in the design of reliable fibre optic interconnection devices, and supports the high demands of modern single mode fibre optic communication infrastructures. This standard is indispensable for manufacturers, testers, and network providers focused on high-quality, durable fibre optic connectivity solutions.
