23、ELECTROTECHNICAL COMMISSION _ FIBRE OPTIC INTERCONECTING DEVICES AND PASSIVE COMPONENTS Part 03-03: Reliability Report on high-power reliability for metal-doped optical fibre plug-style optical attenuators FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization fo
24、r 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 publis
25、hes 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 pa
26、rticipate 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
27、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 Public
28、ations 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 fo
29、r 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 correspon
30、ding 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
31、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
32、 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) Attent
33、ion 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 this IEC Publication may be the subject of patent rights. IEC
34、 shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that whi

41、ntrolled Copy Not for ResaleNo reproduction or networking permitted without license from IHS-,-,- 6 TR 62627-03-03 IEC:2013(E) INTRODUCTION Since 2000, the optical power in transmission systems has increased in conjunction with the increase in the number of channels for DWDM systems, with the help o
42、f deployment of RAMAN amplifiers and application of optical amplifiers. It is pointed out, however, that the transmission media of the optical transmission system such as the optical fibre, optical connector and optical passive components may sometimes be hazardous because of possible leakage of hig
43、h-power light that results in personal injury, melting, or a damage possibly causing a fire. IEC Japan National Committee (JPNC) and Optoelectronics Industry and Technology Development Association (OITDA) carried out the research on the high-power reliability and safety of optical passive components
44、. The result was summarized in the OITDA Technical paper, TP04/SP-PD-2008 “Study on the High-Power Reliability of Optical Passive Parts for Communications.” IEC/TR 62627-03-02 was published based on the above report. According to that report, deterioration of optical passive components at high-power
45、 input is caused by temperature rise due to absorption of light as well as consequential thermal distortion. It was decided to undertake additional research whilst utilizing these findings, specifically on the plug style optical attenuator, whose resistance against high-power is relatively small. Th
46、e study result was summarized in OITDA TP, TP09/SP-PD-2010. This technical report was prepared on the basis of OITDA TP, TP09/SP-PD-2010,“Technical paper of investigation of high-power reliability for plug-style fixed optical attenuators”.
