28、nd noise figure 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 standa

29、rdization 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 preparatio

30、n 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

31、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 subjec

32、ts 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 c

33、ontent 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 pos

34、sible 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 confor

35、mity 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 direct

36、ors, 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

37、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 draw

38、n 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 61290-10-5 has been prepared by 86C: Fibre optic systems and active devices, of IEC

39、technical committee 86: Fibre optics. The text of this standard is based on the following documents: CDV Report on voting 86C/1142/CDV 86C/1233/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has

40、 been drafted in accordance with the ISO/IEC Directives, Part 2. 4 IEC 61290-10-5:2014 IEC 2014 A list of all parts in the IEC 61290 series, published under the general title Optical amplifiers Test methods, can be found on the IEC website. The committee has decided that the contents of this publica

41、tion will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo o

42、n the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. IEC 61290-10-5:2014 IEC 2014 5 OPTICAL AMPLIFIERS TEST METHODS Part 10-5: Multic

43、hannel parameters Distributed Raman amplifier gain and noise figure 1 Scope and object This part of IEC 61290 applies to distributed Raman amplifiers (DRAs). DRAs are based on the process whereby Raman pump power is introduced into the transmission fibre, leading to signal amplification within the t

44、ransmission fibre through stimulated Raman scattering. A detailed overview of the technology and applications of DRAs can be found in IEC TR 61292-6. A fundamental difference between these amplifiers and discrete amplifiers, such as EDFAs, is that the latter can be described using a black box approa

45、ch with well-defined input and output ports. On the other hand, a DRA is basically a pump module, with the actual amplification process taking place along the transmission fibre. This difference means that standard methods described in other parts of IEC 61290 for measuring amplifier parameters, suc

46、h as gain and noise figure, cannot be applied without modification. The object of this standard is to establish uniform requirements for accurate and reliable measurements, using an optical spectrum analyser (OSA), of the following DRA parameters: a) channel on-off gain; b) pump unit insertion loss;

47、 c) channel net gain; d) channel signal-spontaneous noise figure. The measurement method is largely based on the interpolated source subtraction (ISS) method using an optical spectrum analyser, as described and elaborated in IEC 61290-10-4, with relevant modifications relating to a DRA. All numerica

48、l values followed by () are suggested values for which the measurement is assured. Other values may be acceptable but should be verified. NOTE General aspects of noise figure test methods are reported in IEC 61290-3. 2 Normative references The following documents, in whole or in part, are normativel
