Overview

EN 61300-3-49:2013 (CLC adoption of IEC 61300-3-49:2013) defines the procedure to measure the guide pin retention force for rectangular ferrule multi-fibre connectors. The standard ensures guide pins remain securely retained during mating and unmating operations for connector families such as MPO, Mini‑MPO and MT‑RJ. It describes test environment, required apparatus and two accepted measurement methods to support both design verification and routine pass/fail inspection.

Key topics and requirements

• Scope and purpose: Verify the retention of guide pins in rectangular ferrule multi‑fibre connectors so pins do not displace during normal connector handling.
• Applicable connector types: Connectors specified in IEC 61754-7 (MPO), IEC 61754-10 (Mini‑MPO) and IEC 61754-18 (MT‑RJ).
• Test conditions: Controlled environment recommended for precision testing; typical conditions referenced are 22.0 °C to 24.0 °C and 50 ± 10 % RH.
• Apparatus:
  • Fixture that holds the connector without influencing results;
  • Guide pin chuck (recommended retention >> required retention; >200 N ideal when using a tensile testing machine);
  • Weights for pass/fail tests;
  • Tensile testing machine capable of recording/holding maximum force for design verification.
• Two measurement methods:
  • Method A - Weight (pass/fail): Attach a specified weight to the guide pin chuck, apply slowly in‑axis, maintain for at least 5 s, and record whether the pin remains.
  • Method B - Tensile testing machine (design verification): Apply controlled axial tension, measure maximum retention force, and record results.
• Procedure controls: Ensure vertical alignment, axis application of force, consistent fixture placement and adherence to inspection (visual) per IEC 61300-3-1.

Applications and who uses it

• Connector manufacturers: design validation, production qualification and specification compliance.
• Quality assurance and test labs: routine incoming inspection and final inspection using the weight method for pass/fail.
• R&D and reliability engineers: use tensile testing method for quantitative retention data and tolerance studies.
• Systems integrators and spec writers: reference the standard when specifying connector mechanical robustness in data center, telecom and datacom projects.

Related standards

• IEC/EN 61300-1:2011 - General guidance for fibre optic test procedures
• IEC/EN 61300-3-1 - Visual examination
• IEC 61754 series - Connector interface definitions (notably Parts 7, 10 and 18)

This standard is essential when specifying or testing mechanical integrity of guide pins for rectangular ferrule multi‑fibre connectors and supports consistent, reproducible measurements of guide pin retention force.
