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.

INTRODUCTION
An optical channel monitor (OCM) is a dynamic module that measures the optical
characteristics, mainly power and frequency, of each channel present in a dense wavelength
division multiplexing (DWDM) transmission line. The OCM is typically connected to an optical
tap coupler which directs to the OCM anywhere between 1 % and 5 % of the optical signal in
the fibre-optic transmission line. The data reported by the OCM are used in a reconfigurable
optical add/drop multiplexer (ROADM) to dynamically equalize the power in the optical
channels and to monitor the performance of the channels continuously over the lifetime of the
system.

1 Scope
This part of IEC 62343 provides a performance specification template for optical channel
monitors. The objective of this performance specification template is to provide a framework
for the performance specification of the optical channel monitor.
Additional specification parameters may be included for detailed product specifications or
performance specifications. However, specification parameters specified in this document
should not be removed from the detail product specifications or performance specifications.
This document outlines the parameters that are used to specify the performance of the optical
channel monitor.
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 (including any
amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 62343 and
IEC 61280-2-9 apply.
4 Performance specification template
This specification template is a comprehensive compilation of all the performance parameters
that may be relevant to optical channel monitors. Table 1 includes a column that indicates if a
parameter is required or optional. The required parameters include the performance
parameters that are deemed necessary to form a minimal specification. The optional
parameters can be specified in addition to the required parameters depending on the specific
requirements of the transmission system for which it is designed.
The product specification template is given in Table 1. The R/O column refers to whether that
particular specification item could be considered required or optional. The notation of “na”
signifies that no specification is provided in that cell. All Min. and Max. cells left blank shall be
filled in with a specification.
