Failure mode effect analysis is one of the effective and useful analysis methods to determine the reliability evaluation test items and conditions that are defined in future reliability qualification documents.
PD IEC/TR 62343-6-6 is an international standard that focuses on dynamic modules and provide guidance for failure mode effect analysis with optical units of dynamic modules. PD IEC/TR 62343-6-6 describes the dominant failure mode for dynamic modules and relevant tests from IEC 61300-2.
To estimate the lifetime for a module, there is a typical procedure. The first step is to identify the dominant failure modes. The second step is to determine the acceleration tests according to these failure modes. The third step is to carry out the test. The fourth step is to estimate the acceleration factors. Finally, the fifth step is to calculate the lifetime of the dynamic module.
PD IEC/TR 62343-6-6 on dynamic modules and guidelines for failure mode effect analysis is useful for:
There are many types of dynamic modules: dynamic channel equalizer, tenable optical chromatic dispersion compensator, dynamic gain tilt equalizer, wavelength selective switch, wavelength blocker, optical performance monitor, optical switch, and so on. The main purpose of PD IEC/TR 62343-6-6 dynamic modules is to control their performances during operation.
PD IEC/TR 62343-6-6 helps to achieve features, many kinds of control mechanisms are used for dynamic modules; microelectromechanical system, stepping motor, electromagnet, thermo optics, magnet optics, electro-optics, LCD, and so on.
PD IEC/TR 62343-6-6 is necessary to evaluate whole dynamic modules including control circuit boards and firmware if used.
