It contains general guidance fo
22、r the IEC 62343 series related to dynamic devices, and definitions which apply to dynamic devices. The dynamic module, or device, has two distinguishing characteristics: dynamic and module. “Dynamic” highlights the functions of the products to include “tuning, varying, switching, configuring, and ot
23、her continuous optimization,” often accomplished by electronics, firmware, software or their combinations. The dynamic device usually has a certain level of intelligence to monitor or measure the situation and make decisions for necessary (optimization) actions. The behaviour of dynamic modules may
24、be characterized by transient characteristics as the dynamic module undergoes tuning, switching, configuring and other continuous optimization. Characterization of transient characteristics will be considered in individual dynamic module standards. “Module” defines that the products covered by the s
25、tandard are the integration of active and passive components (either or both), through interconnecting materials or devices. The controlling electronics can be inside or outside the optical package (that contains all or most of the optical components and interconnection). The product can look like a
26、 small printed wiring board (PWB or child-board with mounted optical module) or a small box (housing) with optical components and electronics enclosed. In the former case, it is more like an assembly (generally not packaged in a box or housing) than a module (generally packaged in a box or housing).
27、 For historical reasons and convenience, a dynamic module or device is referred to as a dynamic module in the IEC 62343-X series. The number of dynamic modules and devices is rapidly growing as optical communications networks evolve. The following list provides some examples of the products covered
28、by the IEC 62343-X series. It should be noted that the list is not exhaustive and the products to be covered are not limited by the listed examples: channel gain equalizer; dynamic channel equalizer; dynamic gain tilt equalizer; dynamic slope equalizer; tuneable chromatic dispersion compensator; pol
29、arization mode dispersion compensator; reconfigurable optical add-drop multiplexer; switch with monitoring and controls; variable optical attenuator with monitoring and controls. The IEC 62343 series will cover performance templates, performance standards, reliability qualification requirements, har
30、dware and software interfaces, and related testing methods. A complete set of standards related to a dynamic module or device should include the following: optical performance standards; reliability qualification standards; optical performance specification templates; hardware and software interface
31、 standards; test methods; BS EN 62343:2013 6 62343 IEC:2013(E) technical reports. The safety standards related to dynamic modules are mostly optical power considerations, which are covered by IEC TC 76: Optical radiation safety and laser equipment. Only those dynamic modules for which standards are
32、complete or in preparation are included in Clause 3. To reflect the rapidly growing market for dynamic modules, additional terms and definitions will be added in subsequent revisions as the series expands. It should be noted that optical amplifiers could be regarded as dynamic modules. They are not
33、included in the IEC 62343-X series, but are covered in their own series of IEC standards. BS EN 62343:201362343 IEC:2013(E) 7 DYNAMIC MODULES GENERAL AND GUIDANCE 1 Scope and object This International Standard applies to all commercially available optical dynamic modules and devices. It describes th
34、e products covered by the IEC 62343-X series, defines terminology, fundamental considerations and basic approaches. The object of this standard is to establish uniform requirements for operation, reliability and environmental properties of DMs to be implemented in the appropriate DM standard, provid
35、e 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 standard covers performance templates, performance standards, reliability qualification requirement
36、s, 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 re
37、latively 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 eq
