14、ERCONNECTING DEVICES AND PASSIVE COMPONENTS PERFORMANCE STANDARD Part 081-2: Non-connectorized single-mode fibre optic middle-scale 1 N DWDM devices for category C Controlled environments FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization
15、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 publishes International
16、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 participate in this
17、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 between the two o
18、rganizations. 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 Publications have the f
19、orm 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 for any misinterpre
20、tation 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 corresponding national or
21、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 latest edition of this
22、 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, whether direct or indi
23、rect, 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 indispensable for th
24、e 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. A PAS is a technical specification not fulfillin
25、g the requirements for a standard but made available to the public. IEC-PAS 61753-081-2 has been processed by subcommittee 86B: Fibre optic interconnecting devices and passive components, of IEC technical committee 86: Fibre optics The text of this PAS is based on the following document: This PAS wa
26、s approved for publication by the P-members of the committee concerned as indicated in the following document Draft PAS Report on voting 86B/1885A/NP 86B/1908/RVN Following publication of this PAS, which is a pre-standard publication, the technical committee or subcommittee concerned will transform
27、it into an International Standard.

31、middle-scale 1 N (16 N 64) DWDM (Dense Wavelength Division Multiplexing) device shall satisfy in order to be categorized as meeting the IEC standard category C-controlled environments. The requirements cover devices with single- mode non-connectorized pigtails and no circuit-board. There is also a d
32、istinction between small-scale (N 64) 1 N DWDM devices for the purpose of standards. 2 Normative references The following referenced documents are indispensable for the application of this document.

43、document, the following terms and definitions, as well as those given in IEC 62074-1, apply. 3.1 Middle-scale 1 x N DWDM device wavelength-selective branching device which performs functions both of a wavelength multiplexer and demultiplexer with DWDM channel spacing and a number of channel (N) of 1
44、6 64. The device is equipped with no circuit-board including a temperature controller 4 Tests Unless otherwise specified, all test methods are in accordance with IEC 61300-x. Each test defines the number of samples to be evaluated. DWDM devices used for each test are intended to be previously unstre
45、ssed new samples but may also be selected from previously used samples if desired. All measurements shall be carried out at normal room conditions, unless otherwise stated. If the device is provided with an active temperature control, this shall be set at the setpoint specified by the manufacturer.
46、The requirements apply to every combination of input and output port. All tests shall be carried out to validate performance over the required operating wavelength range. As a result, single or multiple spectral bands may be chosen for the qualification, and differing target specifications may be as
47、signed to each spectral band. Table 1 is intended to provide guidance on the wavelength ranges of the various spectral bands. It is not intended for specification. Values of operating wavelength used in performance verification shall be specified between the customer and supplier or shall be as defi
48、ned in the manufacturers specification.
