What is BS EN IEC 62343‑2‑1 - Dynamic modules about?
BS EN IEC 62343 is a series on dynamic modules. Dynamic module is the ratio of stress to strain under vibratory conditions (calculated from data obtained from either free or forced vibration tests, in shear, compression, or elongation). BS EN IEC 62343‑2‑1 provides a reliability qualification test template for dynamic modules (DMs). BS EN IEC 62343‑2‑1 describes the reliability qualification test items and provides information on requirements or options. Example test conditions are given for information purposes in Annex A.
For reliability qualification purposes, some information about the internal components, parts and interconnections is needed. These internal parts are treated as black boxes. BS EN IEC 62343‑2‑1 gives requirements for the evaluation of DM reliability by combining the reliability of such internal black boxes.
The object of BS EN IEC 62343‑2‑1 is to provide a framework for the reliability qualification tests for DMs. Developers of reliability qualification tests for DMs determine the test conditions for each test item by referring to the examples in Annex A.
Who is BS EN IEC 62343‑2‑1 - Dynamic modules for?
BS EN IEC 62343‑2‑1 on Dynamic modules is useful for:
- Administration department
- Design engineers
- Software engineers
- Research and development facilities
Why should you use BS EN IEC 62343‑2‑1 - Dynamic modules?
Dynamic modules are relatively new fibre optic devices. In the industry, there is no de-facto standard of reliability qualification test requirements for Dynamic modules. Also, there are many types and functions of Dynamic modules, such as optical path switching, wavelength management, chromatic dispersion management, optical channel power management, and optical channel powers and wavelength monitoring. Therefore, it is difficult to standardize the reliability qualification test requirements because their functionality is so diverse. For Dynamic modules, a reliability qualification test template rather than particular requirements has been standardized.
Since dynamic modules are relatively new products in the commercial market and involve different technologies, the requirements included in BS EN IEC 62343‑2‑1 is reviewed as technology progresses. BS EN IEC 62343‑2‑1 defines reliability qualification test items. Some test items are requirements; others are optional. BS EN IEC 62343‑2‑1 shows the reliability qualification test items. The right column shows requirements (R) or optional items (O). Reliability qualification developers test the required items and can add tests for the optional items. Using BS EN IEC 62343‑2‑1 you understand a reliability qualification test template for dynamic modules
