What is PD IEC/TR 62627-04 - Fibre optic interconnecting devices and passive components about?
PD IEC/TR 62627 is a series on fibre optic interconnecting devices and passive components. Fibre optic interconnecting devices and passive components ensure an optical function necessary for the proper functioning of the network. PD IEC/TR 62627-04 represents a selected example that concerns the measurement of the attenuation of passive optical components (IEC 61300-3-4), particularly focused on insertion method B for low-loss optical connectors assembled on SM optical fibre.
Who is PD IEC/TR 62627-04 - Fibre optic interconnecting devices and passive components for?
PD IEC/TR 62627-04 on fibre optic interconnecting devices and passive components is useful for:
- Telecommunication component manufacturers
- Telecommunication equipment manufacturers
- Design engineers
- Quality control personnel
Why should you use PD IEC/TR 62627-04 - Fibre optic interconnecting devices and passive components?
Fibre optic interconnecting devices and passive components do not require external energy input because they operate on the optical signal. PD IEC/TR 62627-04 describe the necessary equipment and procedures to measure a specific quantity. The uncertainty budget of every measurement is a key parameter, which should be determined by applying dedicated statistical methods as extensively presented in reference documents like ISO/IEC Guide 98-3:2008. PD IEC/TR 62627-04 hows a possible simple application of these methods for the determination of the measurement uncertainty of optical low loss connector attenuation measurements as defined in IEC 61300-3-4. A detailed analysis of the main uncertainty contributions for single and for repeated measurements is shown, and full mathematical development of the uncertainty budget is given in PD IEC/TR 62627-04. The difference in uncertainty estimation for the measurement of an optical connection compared to the measurement of an optical connector against a reference connector is also discussed.
The reference document for general uncertainty calculations is ISO/IEC Guide 98-3:2008 and PD IEC/TR 62627-04 does not intend to replace it, it only represents an example and should be used in combination with ISO/IEC Guide 98-3:2008. A brief introduction to the determination of a measurement uncertainty according to ISO/IEC Guide 98-3:2008is given in PD IEC/TR 62627-04. Uncertainty calculations should preferably be performed using a linear representation of the relevant quantities. In PD IEC/TR 62627-04, all calculations are performed using linear scales, but results are also presented in logarithmic scale since logarithmic units such as dB or dBm are in common use in fibre optics. This analysis assumes uncorrelated quantities, which is usually an acceptable assumption when considering simple attenuation measurements. Using PD IEC/TR 62627-04 you can represent a selected example that concerns the measurement of the attenuation of passive optical connectors.
