Dynamic modules - Part 5-2: Test methods - 1xN fixed-grid WSS - Dynamic crosstalk measurement

IEC 62343-5-2:2018 describes the measurement methods of dynamic crosstalk during port switching for 1 x N fixed-grid wavelength selective switches (WSSs). The objective of this document is to establish a standard test method for different-channel dynamic crosstalk and same-channel dynamic crosstalk that occur when a particular optical channel signal is switched to the specific branching port against a common port in ITU‑T 50 GHz and 100 GHz fixed grid 1 x N (N ≥ 3) WSSs.

Modules dynamiques - Partie 5-2: Méthodes d'essai - Commutateurs sélectifs en longueur d'onde à grille fixe 1 x N - Mesure de diaphonie dynamique

IEC 62343-5-2: 2018 décrit les méthodes de mesure de diaphonie dynamique pendant la commutation des ports pour les commutateurs sélectifs en longueur d'onde à grille fixe 1 x N. Le présent document a pour but d'établir une méthode d'essai normalisée sur la diaphonie dynamique sur différents canaux et la diaphonie dynamique sur un même canal qui se produisent lorsque le signal d'un canal optique particulier est commuté sur le port de couplage spécifique par rapport à un port commun dans des commutateurs sélectifs en longueur d'onde à grille fixe 1 x N (N ≥ 3) de 50 GHz et 100 GHz selon l'UIT-T. Mots clés: diaphonie dynamique

Dinamični moduli - 5-2. del: Preskusne metode - 1xN WSS s fiksno mrežo - Merjenje dinamičnega presluha (IEC 62343-5-2:2018)

Ta del IEC 62343 opisuje metode merjenja dinamičnega preklopnega odmeva med preklapljanjem vrat za 1 x N stikal za izbiro valovne dolžine (WSSs) v fiksnem omrežju.
Cilj tega dokumenta je določiti standardno metodo preskušanja za dinamični preklopni odmev različnih kanalov in dinamični preklopni odmev istega kanala, do katerih pride, ko posamezni signal optičnega kanala preklopi na določena razvejilna vrata ob skupnih vratih v fiksnem omrežju ITU-T 50 GHz in 100 GHz 1 x N (N ≥ 3) WSSs.

FOREWORD
1) The International Electrotechnical Commission (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 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 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 accordance 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
interested 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 responsible 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
between 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 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
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 Publication 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
