Fibre optic communication subsystem test procedures - Part 1-3: General communication subsystems - Central wavelength and spectral width measurement
IEC 61280-1-3:2010 provides definitions and measure procedures for several wavelength and spectral width properties of an optical spectrum associated with a fibre optic communication subsystem, an optical transmitter, or other light sources used in the operation or test of communication subsystems. The measurement is done for the purpose of system construction and/or maintenance. In the case of communication subsystem signals, the optical transmitter is typically under modulation. NOTE - Different properties may be appropriate to different spectral types, such as continuous spectra characteristic of light-emitting diodes (LEDs), and multilongitudinal-mode (MLM), multitransverse-mode (MTM) and single-longitudinal mode (SLM) spectra, characteristic of laser diodes (LDs). This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision with changes reflecting new laser technology and includes a second method modified for state of the art instrumentation. Keywords: definitions and measure procedures for several wavelength and spectral width properties of an optical spectrum, optical transmitter, test of communication subsystems
Procédures d'essai des sous-systèmes de télécommunication à fibres optiques - Partie 1-3: Sous-systèmes généraux de télécommunication - Mesure de la longueur d'onde centrale et de la largeur spectrale
La CEI 61280-1-3:2010 fournit des définitions et des procédures de mesure pour plusieurs propriétés de longueur d'onde et de largeur spectrale d'un spectre optique associées à un sous-système de télécommunication à fibres optiques, un émetteur optique ou d'autres sources de lumière utilisées pour l'exploitation ou les essais des sous-systèmes de télécommunication. Le mesurage est effectué pour les besoins de la construction et/ou de la maintenance d'un système. Dans le cas des signaux dans les sous-systèmes de télécommunication, l'émetteur optique fonctionne généralement en modulation. NOTE - Des propriétés différentes peuvent être appropriées pour des types de spectres différents, telles que les caractéristiques spectrales continues des diodes électroluminescentes (LED), les spectres de mode multilongitudinal (MLM), de mode multitransversal (MTM) et de mode monolongitudinal (SLM), qui sont caractéristiques des diodes lasers (LD). Mots clés: définitions et des procédures de mesure pour plusieurs propriétés de longueur d'onde et de largeur spectrale d'un spectre optique, émetteur optique, essais des sous-systèmes de télécommunication

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 standardization 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 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 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 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 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 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 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 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 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 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. 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 shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61280-1-3 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86.
This second edition cancels and replaces the first edition published in 1998. This edition
constitutes a technical revision with changes reflecting new laser technology and includes a
second method modified for state of the art instrumentation.

communication subsystem test procedures, on the IEC website.
The committee has decided that the contents of this amendment and the base 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
