26、nal 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 standardization in the electrical and electronic
27、 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 preparation is entrusted to technical committees; an
28、y 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 the International Organization for Standard
29、ization (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 subjects since each technical committee has repre
30、sentation 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 content of IEC Publications is accurate, IEC
31、 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 possible in their national and regional public
32、ations. 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 conformity assessment services and, in some areas
33、, 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 directors, employees, servants or agents includin
34、g 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 out of the publication, use of, or reliance
35、 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 drawn to the possibility that some of the eleme
36、nts 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 61280-1-1 has been prepared by subcommittee 86C: Fibre optic systems and active devices, of IEC technical committee 86: Fibre o
37、ptics. This second edition cancels and replaces the first edition published in 1998. This second edition constitutes a technical revision. The significant technical change with respect to the previous edition is the inclusion of Annex A on how to account for uncertainties. There are editorial correc
38、tions throughout the document and updates to references. 4 61280-1-1 IEC:2013(E) The text of this standard is based on the following documents: CDV Report on voting 86C/1065/CDV 86C/1098/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicat
39、ed in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 61280 series, published under the general title Fibre optic communication subsystem basic test procedures, can be found on the IEC website. The committee has dec
40、ided that the contents of this publication 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 amend
41、ed. A bilingual version of this publication may be issued at a later date. 61280-1-1 IEC:2013(E) 5 FIBRE OPTIC COMMUNICATION SUBSYSTEM BASIC TEST PROCEDURES Part 1-1: Test procedures for general communication subsystems Transmitter output optical power measurement for single-mode optical fibre cable
42、 1 Scope and object This part of IEC 61280 applies to fibre optic general communication subsystems. The object of this part is to measure the optical power coupled from the output of a transmitter under test into single-mode optical fibre cable containing dispersion-unshifted fibre or dispersion-shi
43、fted fibre. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (includi
44、ng any amendments) applies.

45、aratus 3.1 Optical power meter The optical power meter shall be capable of measuring the range of power at wavelengths provided by the transmitter. The optical power meter shall have a resolution of at least 0,1 dB. The meter shall have a detecting surface of sufficient size to capture all the power
46、 coming from the fibre that is put into it. 3.2 Input signal source The input signal source is a signal generator at the appropriate signal rate of the system interface. 3.3 Test cord A length of single-mode optical fibre cable, which is known to remove cladding modes, shall be used. The optical fib
47、re (cable) shall be terminated at both ends with appropriate connectors. The ends for connection to the fibre optic transmitter and to the optical power meter shall be terminated with appropriate connector plugs. These plugs and any adapters necessary to produce the connections shall be such that th
48、e performance can be specified by the manufacturer of the equipment or the connectors. Values for the insertion loss repeatability shall be known. 6 61280-1-1 IEC:2013(E) 3.4 Calibration The optical power meter shall be configured and calibrated for the test wavelength. The optical power meters shal
49、l be calibrated in accordance with IEC 61315.
