IEC 62343:2017 pdf download.Dynamic modules – General and guidance
1 Scope
IEC 62343 applies to all commercially available optical dynamic modules and devices. It describes the products covered by the IEC 62343 series, defines terminology, fundamental considerations and basic approaches. The object of this document is to • establish uniform requirements for operation, reliability and environmental properties of dynamic modules (DMs) to be implemented in the appropriate DM standard, and • provide assistance to the purchaser in the selection of consistently high-quality DM products for his particular applications, as well as in the consultation of the appropriate specific DM standard(s). This document covers performance templates, performance standards, reliability qualification requirements, hardware and software interfaces and related testing methods. Since a dynamic module integrates an optical module/device, printed wiring board, and software/firmware, the standards developed in the series will mimic appropriate existing standards. On the other hand, since “dynamic module” is a relatively new product category, the dynamic module standards series will not be bounded by the existing practices where requirements differ. The safety standards as related to dynamic modules are mostly optical power considerations, which is covered by IEC TC 76: Optical radiation safety and laser equipment.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-731 and IEC TR 61 931 and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/NOTE 1 Some terms and definitions included in this document were first published in IEC 62343 (all parts). After the publication of this document, these terms and definitions will be removed from IEC 62343 (all parts) when the series is revised, and reference will be made to IEC 62343. NOTE 2 The terms and definitions listed in Clause 3 refer to the meaning of the terms and definitions used in the specifications of DMs. Only those parameters listed in the appropriate performance standard in IEC 62343-1 (all parts) and performance specification templates in IEC 62343-3 (all parts) are intended to be specified. NOTE 3 The list of parameter definitions of DMs given in Clause 3 is divided into subclauses by the type of DM. 3.1 General terms and definitions 3.1.1 optical dynamic device optical device designed to monitor and control dynamically some characteristics of one or more optical signals, by means of suitable electronic controls, in order to improve or to maintain definite performances of the system in which it is intended to be inserted Note 1 to entry: Said characteristics may include optical paths, optical intensities, spectral characteristics, polarization states, dispersion, etc. Note 2 to entry: Optical dynamic devices may comprise optical active and optical passive elements or components. Note 3 to entry: The control/response time of optical dynamic devices is much larger than the signal time characteristics and typically may range from few microseconds to tens of seconds.
