1 Scope
This document 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 their 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 bound by the existing practices where requirements differ.
The safety standards as related to dynamic modules are mostly optical power considerations,
which is covered by the IEC 60825 series (see Clause 6).
