Optical amplifiers - Part 2: Single channel applications - Performance specification template

IEC 61291-2:2023 is available as IEC 61291-2:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 61292-2:2023 provides a performance specification template applicable to optical amplifiers (OAs) used in single channel applications. Multichannel applications are covered in IEC 61291-4. The objective of this template is to provide a framework for the preparation of performance standards and/or product specifications defining the performance of OA devices used in single channel applications. In addition to the requirements specified in this template, a performance standard or product specification could include other parameters, such as ratings, operating conditions, tests, and pass/fail criteria. For a particular application, product specification writers could add specification parameters and/or groups of specification parameters to this template, without removing the parameters specified in this document. This fifth edition cancels and replaces the fourth edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- the test methods for gain ripple in Table 2, Table 4 and Table 6 refer now to the IEC 61290‑1 series;
- the SOA definition (3.1.3) refers now to IEC 61931.

IEC 61291-2:2023 est disponible sous forme de IEC 61291-2:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

L'IEC 61292-1:2023 fournit un modèle de spécifications de performances applicable aux amplificateurs optiques (AO) utilisés dans le cadre d’applications à un seul canal. Les applications multicanaux sont couvertes dans l’IEC 61291-4. L’objectif de ce modèle est de fournir un cadre pour l’établissement de normes de performances et/ou de spécifications de produit définissant les performances des dispositifs AO utilisés dans le cadre d’applications à un seul canal. En plus des exigences spécifiées dans ce modèle, une norme de performances ou une spécification de produit peut inclure d’autres paramètres, tels que des valeurs assignées, des conditions de fonctionnement, des essais et des critères de succès/défaillance. Pour une application particulière, les rédacteurs de spécifications de produit peuvent ajouter des paramètres de spécification et/ou des groupes de paramètres de spécification à ce modèle, sans supprimer les paramètres spécifiés dans le présent document. Cette cinquième édition annule et remplace la quatrième édition parue en 2016. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
- les méthodes d’essai pour l’ondulation du gain dans le Tableau 2, le Tableau 4 et le Tableau 6 font maintenant référence à la série IEC 61290-1;
- la définition de SOA (3.1.3) fait maintenant référence à l’IEC 61931.

39 FOREWORD

40 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

41 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

42 international co-operation on all questions concerning standardization in the electrical and electronic fields. To

43 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

44 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

45 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

46 in the subject dealt with may participate in this preparatory work. International, governmental and non-

47 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

48 with the International Organization for Standardization (ISO) in accordance with conditions determined by

49 agreement between the two organizations.

50 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

51 consensus of opinion on the relevant subjects since each technical committee has representation from all

52 interested IEC National Committees.

53 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

54 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

55 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

56 misinterpretation by any end user.

57 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

58 transparently to the maximum extent possible in their national and regional publications. Any divergence

59 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

60 the latter.

61 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

62 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

63 services carried out by independent certification bodies.

64 6) All users should ensure that they have the latest edition of this publication.

65 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

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

67 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

68 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

69 Publications.

70 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

71 indispensable for the correct application of this publication.

72 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

73 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

74 IEC 61291-2 has been prepared by subcommittee 86C: Fibre optic systems and active

75 devices, of IEC technical committee 86: Fibre optics. It is an International Standard.

76 This fifth edition cancels and replaces the fourth edition published in 2016. This edition

77 constitutes a technical revision.

78 This edition includes the following significant technical changes with respect to the previous

79 edition:

80 a) the test methods for gain ripple in Table 2, Table 4 and Table 6 refer now to the IEC

81 61290-1 series;

82 b) the SOA definition (3.1.3) refers now to IEC 61931, Fibre optic - Terminology.

103 INTRODUCTION

104 This International Standard is devoted to the subject of optical amplifiers. The technology of

105 optical amplifiers is still rapidly evolving, hence amendments and new additions to this

106 standard can be expected. Each abbreviation introduced in this standard is generally

107 explained in the text the first time it appears. However, for an easier understanding of the

108 whole text, a list of all abbreviations used in this standard is given in Clause 3.
