Overview

EN 62343-3-2:2016 (IEC 62343-3-2:2016) is a performance specification template for optical channel monitors (OCM) within the Dynamic Modules family. The document provides a standardized framework for specifying OCM performance parameters used in dense wavelength-division multiplexing (DWDM) systems. It is intended to be included in product or performance specifications - required parameters must be retained, while additional parameters may be added for detailed product requirements. The OCM template supports applications such as ROADM-based power equalization and continuous channel monitoring.

Key topics and technical requirements

• Template structure and R/O designations: Table 1 in the standard lists performance parameters and marks each as Required (R) or Optional (O) to form a minimal, consistent specification.
• Channel and spectral parameters:
  • Input channel plan and channel frequency range
  • Channel frequency spacing tolerance and frequency error / resolution
  • Reference measurement bandwidth and noise-equivalent bandwidth
• Power and OSNR metrics:
  • Input channel power dynamic range, non‑uniformity, absolute/relative error, variability and resolution intervals
  • Total band power dynamic range and errors
  • OSNR dynamic range, absolute/relative error, variability and resolution
• Polarization and reflection:
  • Polarization dependent errors for channel power, frequency and OSNR
  • Back reflection specification
• Performance timing and environmental:
  • Response time and repeatability time interval
  • Operating and storage temperature and relative humidity ranges
• Test method links: The template references established test standards for measurement methods (e.g., IEC 61280‑2‑9 for OSNR, IEC 61300‑3‑21 for switching/response time, IEC 61300‑3‑29 for spectral transfer characteristics).

Applications and users

Who uses EN 62343-3-2:2016:

• OCM manufacturers - to produce consistent, testable product specifications
• System integrators and DWDM equipment vendors - for component selection and interoperability with ROADMs
• Network operators and designers - to define monitoring requirements for live optical networks and power-equalization control loops
• Test laboratories and procurement teams - to verify compliance and evaluate OCM performance against a standardized template

Practical uses:

• Specifying minimum and optional OCM performance items for DWDM links
• Guiding acceptance tests and factory verification
• Ensuring OCM data quality for dynamic power balancing in ROADM nodes

Related standards

• IEC 61280-2-9 - Optical SNR measurement for DWDM systems

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.

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.
