Overview
EN 61300-3-46:2011 (IEC 61300-3-46:2011) defines a reproducible measurement method for the guide pin bore diameter in thermoplastic and thermoset MT ferrules (as specified in IEC 61754-5). The standard is part of the IEC/CENELEC series on fibre optic interconnecting devices and passive components and describes apparatus, environmental conditions, procedure and post-test examination to determine the effective bore size for connector guide pins.
Key topics and technical requirements
- Scope: Measurement of guide pin bore diameters in MT ferrules used for multi‑fibre connectors.
- Test conditions: Temperature 21.0 °C to 25.0 °C; relative humidity 50 % ± 10 %; total assembly mass 100.0 g ± 5.0 g. Parts must be preconditioned for at least 24 hours.
- Gauge pins and tolerances:
- Traceable, calibrated gauge pins (material: tungsten carbide steel).
- Typical pin diameter series: from 0.69895 mm to 0.70005 mm in 100 nm increments (used to find the largest pin that can be withdrawn under the specified mass).
- Cylindricity: 100 nm or better. Surface finish: 0.2 µm.
- Apparatus: Pin vice, rod and platform to hold calibrated mass elements so the assembly hangs vertically; clean pins and test parts to ensure accurate results.
- Procedure: Insert calibrated gauge pin (rear entry recommended), secure vice, gradually apply the calibrated mass to pull the pin through the bore. Increase pin size until the 100 g ± 5 g mass can no longer pull the pin free; the previous (smaller) pin size is recorded as the effective bore diameter. Repeat for the opposite hole.
- Post-test examination: Visual inspection per IEC 61300-3-1 for damage (e.g., chipping, scratching, bore exit damage).
Applications and who uses this standard
- Connector and ferrule manufacturers: product design validation, production quality control, acceptance testing.
- Test laboratories and QA teams: conformity testing, incoming inspection, and process control to ensure interchangeability and mechanical alignment.
- System integrators and data centre operators: verification of connector compatibility where MT-based high-density multi-fibre connectors are deployed.
- R&D and compliance engineers: development of connector interfaces and documentation for regulatory or customer requirements.
Practical benefits include reliable connector alignment, controlled manufacturing tolerances for multi‑fibre assemblies, and reproducible inspection methods to reduce assembly failures and field returns.
