IEC/TR 62627-04:2012(E) represents a selected example that concerns the measurement of the attenuation of passive optical components (IEC 61300-3-4), particularly focussed on insertion method B for low-loss optical connectors assembled on SM optical fibre (according to IEC 60793-2-50, Type B1.3). Keywords: measurement of the attenuation of passive optical components (IEC 61300-3-4)

Overview

IEC TR 62627-04:2012 is a Technical Report in the IEC 62627 series titled Fibre optic interconnecting devices and passive components – Part 04: Example of uncertainty calculation: Measurement of the attenuation of an optical connector. It gives a worked example for estimating measurement uncertainty when measuring connector attenuation per IEC 61300-3-4 (attenuation of passive optical components), with particular focus on insertion method B for low-loss connectors assembled on single‑mode fibre (IEC 60793-2-50, Type B1.3).

This document is an example - not a replacement - for the general uncertainty guidance in ISO/IEC Guide 98-3:2008 (GUM). It shows the mathematical development of an uncertainty budget and compares uncertainty for measuring a full optical connection versus measuring one connector against a reference connector.

Key topics and technical requirements

Measurement method: Insertion method B - uses a measurement plug (C1), a light source and a power meter to obtain reference power (Pin), then inserts the device under test (DUT, C2) and measures power (Pout).

Attenuation calculation:

Linear scale: A[dB] = −10 · log10(Pout / Pin)
Log scale: A[dB] = Pin(dBm) − Pout(dBm)

Measurement equipment: Light source types S4 or S5 (single‑mode sources at 1 310 nm or 1 550 nm) and a calibrated detector/power meter as defined in IEC 61300-3-4.

Uncertainty analysis:

Identification and quantification of principal uncertainty contributions (power meter, light source, DUT, reference connector/adaptor).
Use of linear representation for calculations (results also presented in logarithmic units such as dB/dBm).
Treatment of combined and expanded uncertainty, with worked examples and tabulated evaluations (see Annexes A and B).
Assumption of uncorrelated quantities for this example, with guidance on when that is acceptable.

Annexes:

Annex A: brief introduction to measurement uncertainty per GUM.
Annex B: full mathematical development of the uncertainty budget for attenuation measurements.

Practical applications and users

IEC TR 62627-04:2012 is valuable for:

Test laboratories performing connector insertion loss measurements and reporting measurement uncertainty.

Manufacturers and quality engineers validating connector performance and process control.

Calibration and metrology personnel preparing uncertainty budgets for optical power/attenuation measurements.

Standards developers and trainers needing an illustrative example of GUM application to fibre‑optic connector attenuation.
