14、INTERNATIONAL ELECTROTECHNICAL COMMISSION _ DYNAMIC MODULES Part 3-2: Performance specification templates Optical channel monitor FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC N
15、ational 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, Technical Reports, Pu
16、blicly 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, governmental and non- gov
17、ernmental 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 agreements of IEC
18、 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 and are accep
19、ted 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 promote internation
20、al 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 indicated in the lat
21、ter. 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) All users shou
22、ld 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 or other dama

IEC 62343-3-2:2016 IEC 2016 5 INTRODUCTION An optical channel monitor (OCM) is a dynamic module that measures the optical characteristics, mainly power and
29、 frequency, of each channel present in a dense wavelength division multiplexing (DWDM) transmission line. The OCM is typically connected to an optical tap coupler which directs to the OCM anywhere between 1 % and 5 % of the optical signal in the fibre-optic transmission line. The data reported by th
30、e OCM are used in a reconfigurable optical add/drop multiplexer (ROADM) to dynamically equalize the power in the optical channels and to monitor the performance of the channels continuously over the lifetime of the system. 6 IEC 62343-3-2:2016 IEC 2016 DYNAMIC MODULES Part 3-2: Performance specifica
31、tion templates Optical channel monitor 1 Scope This part of IEC 62343 provides a performance specification template for optical channel monitors. The objective of this performance specification template is to provide a framework for the performance specification of the optical channel monitor. Addit
32、ional specification parameters may be included for detailed product specifications or performance specifications. However, specification parameters specified in this document should not be removed from the detail product specifications or performance specifications. This document outlines the parame
33、ters that are used to specify the performance of the optical channel monitor. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated

Table 1 includes a column that indicates if a parameter is requir
38、ed or optional. The required parameters include the performance IEC 62343-3-2:2016 IEC 2016 7 parameters that are deemed necessary to form a minimal specification. The optional parameters can be specified in addition to the required parameters depending on the specific requirements of the transmissi
39、on system for which it is designed. The product specification template is given in Table 1. The R/O column refers to whether that particular specification item could be considered required or optional. The notation of “na” signifies that no specification is provided in that cell.
