Description (English):

IEC 61000-3-45:2023 describes the procedure required to measure the statistical distribution and mean attenuation for random mated optical connectors with physical contact (PC) and angled physical contact (APC) polished multi-fibre rectangular ferrules as defined in the IEC 61754 series. This measurement method is applicable to cable assemblies. This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of sample size for > 12-fibre connector measurement; b) inclusion of guidance for multimode measurement.

Abstract

Overview

IEC 61300-3-45:2023 specifies standardized test procedures to measure the attenuation of random mated multi‑fibre connectors. The standard defines how to obtain the statistical distribution and mean attenuation for one‑row multi‑fibre rectangular ferrule connectors with PC (physical contact) and APC (angled physical contact) polishing, as referenced in the IEC 61754 series. The methods apply to cable assemblies and provide repeatable, unbiased results for design approval and production control.

Key topics and requirements

Scope of measurement: Statistical distribution and mean attenuation for random mating of multi‑fibre connectors (PC and APC) using cable assemblies.
Two test methods:
- Method 1 - Reference design‑approval procedure using pinned (“launch test plugs”) and unpinned plugs in a predefined test matrix. Intended as the authoritative method in disputes.
- Method 2 - Practical procedure for process control using selected reference and test cords; suitable for routine verification after design approval.
Random sampling: Cable assemblies and any adaptors must be chosen at random to ensure statistically unbiased estimates.
Launch and detection: Procedures include requirements for launch conditions, light sources (LS), detectors (D), and analysis of results (see apparatus and analysis sections).
Test matrices and labelling: Detailed matrices for 2‑, 4‑, 8‑, 10‑, 12‑ and >12‑fibre connectors are specified to organize measurements and reporting.
Multimode guidance: This edition adds specific guidance and normative annex content for multimode measurements (launch fibre and launch plug requirements).
Sample size updates: New sample size rules for connectors with more than 12 fibres.
Reporting: The standard defines the calculation, analysis and the details to be specified and reported for traceability.

Applications and practical value

Ensures consistent, repeatable attenuation data for multi‑fibre connectors used in high‑density fibre systems (e.g., data centres, telecom trunks, MPO/MTP® style assemblies).
Supports design validation, supplier qualification and production process control by providing objective criteria for connector mating loss.
Used by:
- Test and calibration laboratories
- Cable and connector manufacturers
- Quality assurance and incoming inspection teams
- System integrators and network operators evaluating batch performance
Practical outputs include mean loss values, distribution statistics and pass/fail assessment for batches of cable assemblies.
