Fibre optic interconnecting devices and passive components - Reliability. Report of high power transmission test of specified passive optical components1 Scope This part of IEC 62627 describes test data relating to high power damage of fixed optical attenuators, optical isolators and optical splitters (non wavelength selective branching devices). It also describes the test of thermal simulation and failure mechanism analysis for the above passive optical components on high power transmission.

This helps in determining the material characteristics of the micro-electromechanical systems
