22、C 2016 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ DYNAMIC MODULES Part 4-1: Software and hardware interface 1 x 9 wavelength selective switch FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical co

23、mmittees (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 in addition to other activities, IEC publishes International Standards, Technical Specifications, Techni

24、cal 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 interested in the subject dealt with may participate in this preparatory work. International, government

25、al and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agr

26、eements 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 interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use

27、 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 responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promo

28、te international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indica

29、ted 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 conformity. IEC is not responsible for any services carried out by independent certification bodies. 6)

30、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 members of its technical committees and IEC National Committees for any personal injury, property damage

31、 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 Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this public

32、ation. 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 Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all suc

33、h patent rights. International Standard IEC 62343-4-1 has been prepared by subcommittee SC86C: Fibre optic systems and active devices, of IEC technical committee 86: Fibre optics. The text of this standard is based on the following documents: CDV Report on voting 86C/1304/CDV 86C/1346/RVCFull inform

34、ation on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

BS EN 62343-4-1:2016 4 IEC 62343-4-1:2016 IEC 2016 The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publicat

36、ion. At this date, the publication will be g120 reconfirmed, g120 withdrawn, g120 replaced by a revised edition, or g120 amended. A bilingual version of this publication may be issued at a later date. BS EN 62343-4-1:2016IEC 62343-4-1:2016 IEC 2016 5 INTRODUCTION A wavelength selective switch (WSS)

37、is a dynamic module, which is mainly used in a reconfigurable optical add drop multiplexer (ROADM) system to switch all wavelength signals to their respective required output port in dense wavelength division multiplexing (DWDM) networks. The WSS module has one input port and a plurality of output p

38、orts (i.e. 1 x N WSS) and can be used reversely, such as N input ports and one output port, depending on its application. It is electrically controlled with software, which directs each wavelength signal among an input DWDM signal from one input port to the required output port for each wavelength s

39、ignal. BS EN 62343-4-1:2016 6 IEC 62343-4-1:2016 IEC 2016 DYNAMIC MODULES Part 4-1: Software and hardware interface 1 x 9 wavelength selective switch 1 Scope This part of IEC 62343 describes and provides specifications for a software and hardware interface for the 1 x 9 wavelength selective switch.

40、These switches can be controlled by resident firmware with this interface. This standard addresses the configuration and function to control a WSS. This interface is intended to enable a user or host to retrieve the switch status and/or adjust relevant switch and attenuation settings. 2 Normative re

47、ctions of the WSS module and be the primary interface to command the unit. The HC controls the WSS module by sending control signal, as well as command data, to the WSS module via a 12-bit address bus, a 16-bit data bus, and DPRAM related signal lines such as Read/Write, Chip Enable, and Output Enab

48、le. The HC also receives from the WSS module response signals and status data. Any address within the DPRAM can be written to via the HC, however many of these values will be overwritten upon the application of a command to the WSS module. The addresses, which are identified as inputs, can be found

49、further along in this document. In addition to the DPRAM interface, RS232 serial communication is also supported by the WSS module. The WSS module has a non-volatile memory to store the latest setting when requested. A functional diagram of the WSS module controls is illustrated in Figure 1 below.
