16、ission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

17、in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)“). Their preparation is entrusted to technical committees; any IEC National Committee

18、interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accorda

19、nce with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all inter

20、ested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsi

21、ble for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence b

22、etween any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of

23、 conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

24、 members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publicat

25、ion or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publicat

26、ion may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62343 has been prepared by subcommittee 86C: Fibre optic systems and active devices, of IEC technical committee 86: Fibre optics. This second edition c

27、ancels and replaces the first edition published in 2013. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: the inclusion of definitions for the wavelength selective switch. The text of this Internatio

28、nal Standard is based on the following documents: FDIS Report on voting 86C/1444/FDIS 86C/1450/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Dire

29、ctives, Part 2. 4 IEC 62343:2017 IEC 2017 A list of all the parts in the IEC 62343 series, published under the general title Dynamic modules, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on t

30、he IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at a later date.

31、RODUCTION IEC 62343 applies to dynamic devices as defined in IEC TS 62538. This document contains general guidance for the IEC 62343 series related to dynamic devices and definitions which apply to dynamic devices. The dynamic module (DM), or device, has two distinguishing characteristics: dynamic a

32、nd module. “Dynamic“ highlights the functions of the products to include “tuning, varying, switching, configuring, and other continuous optimization,“ often accomplished by electronics, firmware, software or their combinations. The dynamic device usually has a certain level of intelligence to monito

33、r or measure the situation and make decisions for necessary (optimization) actions. The behaviour of dynamic modules may be characterized by transient characteristics as the dynamic module undergoes tuning, switching, configuring and other continuous optimization. Characterization of transient chara

34、cteristics will be considered in individual dynamic module standards. “Module“ defines that the products covered by the standard are the integration of active and passive components (either or both), through interconnecting materials or devices. The controlling electronics can be inside or outside t

35、he optical package (that contains all or most of the optical components and interconnection). The product can look like a 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 m

36、ore like an assembly (generally not packaged in a box or housing) than a module (generally packaged in a box or housing). For historical reasons and convenience, a dynamic module or device is referred to as a dynamic module in the IEC 62343 series. The number of dynamic modules and devices is rapidl

37、y growing as optical communications networks evolve. The following list provides some examples of the products covered by the IEC 62343 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 ch

38、annel equalizer; dynamic gain tilt equalizer; dynamic slope equalizer; tuneable chromatic dispersion compensator; polarization mode dispersion compensator; reconfigurable optical add-drop multiplexer; switch with monitoring and controls; variable optical attenuator with monitoring and controls; opti

39、cal channel monitor; wavelength selective switch; multicast optical switch. The IEC 62343 series will cover performance templates, performance standards, reliability qualification requirements, hardware and software interfaces, and related testing methods. The structure of the IEC 62343 series, unde

40、r the general title Dynamic modules, is as follows: 62343-1 series Part 1: Performance standards 62343-2 series Part 2: Reliability qualification 6 IEC 62343:2017 IEC 2017 62343-3 series Part 3: Performance specification templates 62343-4 series Part 4: Software and hardware interface standards 6234

41、3-5 series Part 5: Test methods 62343-6 series Part 6: Design guides 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

42、interface standards; test methods; 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 complete or in preparation a

43、re 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 included in the IEC 62343 se

44、ries but are covered in their own series of IEC standards. IEC 62343:2017 IEC 2017 7 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, funda

45、mental 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

46、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 te

47、sting 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

48、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. 2 Normative references The following docu
