31、ONAL ELECTROTECHNICAL COMMISSION _ FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC FILTERS GENERIC SPECIFICATION FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees
32、(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 publishes International Standards, Technical Specifications, Technical Repor
33、ts, 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 participate in this preparatory work. International, governmental and no
34、n-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 between the two organizations. 2) The formal decisions or agreements o
35、f 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 Publications have the form of recommendations for international use and are
36、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 for any misinterpretation by any end user. 4) In order to promote intern
37、ational 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 corresponding national or regional publication shall be clearly indicated in th
38、e 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 services carried out by independent certification bodies. 6) All users
39、 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 National Committees for any personal injury, property damage or other
40、 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) Attention is drawn to the Normative references cited in this publication. Us
41、e 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 shall not be held responsible for identifying any or all such patent
42、rights. International Standard IEC 61977 has been prepared by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics. This third edition cancels and replaces the second edition published in 2010. It constitutes a technical revision.
43、This edition includes the following significant technical changes with respect to the previous edition: a) harmonization of a number of terms and definitions with other generic specifications; b) deletion of the quality assessment level clause. BS EN 61977:2015IEC 61977:2015 IEC 2015 5 The text of t
44、his standard is based on the following documents: CDV Report on voting 86B/3861/CDV 86B/3917/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 been drafted in accordance with the ISO/IEC Direct
45、ives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, repla
46、ced by a revised edition, or amended. BS EN 61977:2015 6 IEC 61977:2015 IEC 2015 FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS FIBRE OPTIC FILTERS GENERIC SPECIFICATION 1 Scope This International Standard applies to the family of fibre optic filters. These components have all of the fol
47、lowing general features: they are passive for the reason that they contain no optoelectronic or other transducing elements which can process the optical signal launched into the input port; they modify the spectral intensity distribution in order to select some wavelengths and inhibit others; they a
48、re fixed, i.e. the modification of the spectral intensity distribution is fixed and cannot be tuned; they have input and output ports or a common port (having both functions of input and output) for the transmission of optical power; the ports are optical fibre or optical fibre connectors; they diff
49、er according to their characteristics. They can be divided into the following categories: short-wave pass (only wavelengths lower than or equal to a specified value are passed); long-wave pass (only wavelengths greater than or equal to a specified value are passed); band-pass (only an optical window is allowed); notch (only an optical window is inhibited). It is also possible to have a combination of the above categories. This stand
