14、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 publ
15、ishes 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
16、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 agreemen
17、t 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 Publ
18、ications 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
19、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 corresp
20、onding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the lat
21、est 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, whe
22、ther 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 i
23、ndispensable 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 such patent rights. International standard IEC 61
24、291-1 has been prepared by subcommittee 86C: Fibre optic systems and active devices, of IEC technical committee 86: Fibre optics. This second edition cancels and replaces the first edition published in 1998. It is a technical revision that includes the following significant changes: the applicabilit
25、y has been extended to all commercially available optical amplifiers, not just optical fiber amplifiers, and definitions for multichannel amplifiers are included. The text of this standard is based on the following documents: FDIS Report on voting 86C/705/FDIS 86C/729/RVD Full information on the vot

29、g clients of the SABS .61291-1 IEC:2006 9 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. SANS 61291-1:2007This s tandard may
30、only be used and printed by approved subscription and freemailing clients of the SABS .61291-1 IEC:2006 11 OPTICAL AMPLIFIERS Part 1: Generic specification 1 Scope and object This part of IEC 61291 applies to all commercially available optical amplifiers (OAs) and optically amplified assemblies. It
31、applies to OAs using optically pumped fibres (OFAs based either on rare-earth doped fibres or on the Raman effect), semiconductors (SOAs), and waveguides (POWAs). The object of this standard is: to establish uniform requirements for transmission, operation, reliability and environmental properties o
32、f OAs; to provide assistance to the purchaser in the selection of consistently high-quality OA products for his particular applications. Parameters specified for OAs are those characterizing the transmission, operation, reliability and environmental properties of the OA seen as a “black box” from a
33、general point of view. In the sectional and detail specifications a subset of these parameters will be specified according to the type and application of the particular OA device or assembly. 2 Normative references The following referenced documents are indispensable for the application of this docu

43、n, characteristics and applications 3 Terms, definitions and abbreviations 3.1 Overview The definitions listed in this clause refer to the meaning of the terms used in the specifications of OAs. Only those parameters listed in the appropriate specification template, as in IEC 61291-2 and IEC 61291-4
44、, are intended to be specified. NOTE 1 The numbered terms in this clause are indexed and cross-referenced in Annex A. The list of parameter definitions of OAs, given in this clause, is divided into two parts: the first part, in 3.2, lists those parameters relevant for OA devices, namely power, pre-,
45、 line-, and distributed amplifiers; the second part, in 3.3 lists the parameters relevant for optically amplified, elementary assemblies, namely the optically amplified transmitter (OAT) and the optically amplified receiver (OAR).

46、ved subscription and freemailing clients of the SABS .61291-1 IEC:2006 15 In any case where the value of a parameter is given for a particular device, it will be necessary to specify certain appropriate operating conditions such as temperature, bias current, pump optical power, etc. In this clause,
47、two different operating conditions are referred to: nominal operating conditions, which are those suggested by the manufacturer for normal use of the OA, and limit operating conditions, in which all the parameters adjustable by the user (e.g. temperature, gain, pump laser injection current, etc.) ar
48、e at their maximum values, according to the absolute maximum ratings stated by the manufacturer. The OA shall be considered as a “black box”, as shown in Figure 1. The OA device shall have two optical ports, namely an input and an output port (Figure 1a). The OAT and OAR are to be considered as an O
49、A integrated on the transmitter side or on the receiver side, respectively. Both kinds of integration imply that the connection between the transmitter or the receiver and the OA is proprietary and not to be specified. Consequently, only the optical output port can be defined for the OAT (after the OA, as shown in Figure 1b) and only the optical in
