4 EN : Foreword The text of document 86C/774/CDV, future edition 2 of IEC , prepared by SC 86C, Fibre optic systems and active devices, of IEC TC 86, Fibre optics, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN on This European Standard supersedes EN :2003. The main significant changes are the following: the applicability has been extended to all commercially available optical amplifiers, not just optical fibre amplifiers; Clause 7, EMC, has been added; references to applicable test methods have been updated. This standard is to be used in conjunction with EN :2006. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) latest date by which the national standards conflicting with the EN have to be withdrawn (dow) Annex ZA has been added by CENELEC. Endorsement notice The text of the International Standard IEC :2008 was approved by CENELEC as a European Standard without any modification. In the official version, for Bibliography, the following note has to be added for the standard indicated: IEC NOTE Harmonized in EN series (not modified).

8 IEC: INTRODUCTION This International Standard is devoted to the subject of optical amplifiers. The technology of optical amplifiers is still rapidly evolving, hence amendments and new editions to this standard can be expected. Each abbreviation introduced in this International Standard is generally explained in the text the first time it appears. However, for an easier understanding of the whole text, a list of abbreviations used in this International Standard is given in 3.3.
9 IEC:2008 OPTICAL AMPLIFIERS Part 4: Multichannel applications Performance specification template 1 Scope This part of IEC applies to optical amplifier (OA) devices and sub-systems to be used in multichannel applications. The object of this performance specification template is to provide a frame for the preparation of detail specifications on the performances of OA devices and sub-systems to be used in multichannel applications. Detail product specification writers may add specification parameters and/or groups of specification parameters for particular applications. However, detail specification writers may not remove specification parameters specified in this standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
