Overview

IEC TR 62343-6-2:2013 - "Dynamic modules, Part 6-2: Design guide - Software and hardware interfaces - Survey results" is a technical report from the IEC that clarifies which software and hardware interfaces of dynamic modules should be standardized based on industry surveys. It summarizes regional responses (Annex A) and includes a dedicated survey for the optical channel monitor (OCM) (Annex B). This second edition (2013) replaces the 2009 edition and adds OCM-specific survey data while updating terminology (OPMON → OCM).

Key topics

• Scope and objective: Proposes a recommended software and hardware interface standard for dynamic modules defined in the IEC 62343 series; presents survey-driven evidence rather than prescriptive normative clauses.
• Survey methodology: Requests sent to 55 companies; 28 effective replies (12 users, 13 suppliers, 3 both); survey period Sep–Oct 2004. Results are summarized by region and by device type.
• Interface layer model: Defines three interface points (Figure 1):
  • Interface A - electrical/analog fundamental interface (heaters, motors, simple TTL/CMOS signals).
  • Interface B - local control interfaces such as dual-port RAM, I²C.
  • Interface C - higher-level system buses and communication (Ethernet, PCI/compact‑PCI, GP‑IB, RS‑232/RS‑485, USB, proprietary buses).
• Common interfaces identified: DP‑RAM, RS‑232C, I²C, Ethernet, PCI/compact‑PCI, RS‑485, USB, GP‑IB. Survey results show a mix of proprietary and standard interfaces in use for different module types.
• Device coverage: Survey covers many dynamic modules - e.g., WSS, VOA (single/array), DGE/DSE, DCDC, DPMDC, ROADM, optical spatial switches, tunable filters and OCM.

Applications

• Product designers and manufacturers: Use the report to align module hardware and firmware interfaces for better interoperability and easier system integration.
• System integrators and network equipment vendors: Leverage guidance to select modules that fit standardized control and management interfaces, reducing custom integration effort.
• Test & measurement and field support teams: Benefit from understanding commonly used interface types for maintenance, diagnostics and lifecycle support.
• Standards developers and program managers: Use the survey evidence to prioritize interface standardization work within the IEC 62343 series.

Practical value

• Helps reduce proprietary fragmentation by identifying widely adopted interfaces and priorities for standardization.
• Supports interoperability across dynamic optical modules and host systems, improving scalability and reducing time-to-market.
• Annex B provides targeted insight for OCM (optical channel monitor) interface preferences and behavior.

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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 62343-6-2, which is a technical report, has been prepared by subcommittee 86C: Fibre
optic systems and active devices, of IEC technical committee 86: Fibre optics.
This second edition cancels and replaces the first edition published in 2009. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the survey results of the software and hardware interface of OCM have been added as
Annex B, which was presented at the IEC Seattle meeting in 2010. The results are in
agreement with the general conclusion of the first edition.

b) OPMON (optical performance monitor) in the body of the text has been changed to OCM
(optical channel monitor) for consistency with the latest definitions.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
86C/1124/DTR 86C/1149/RVC
Full information on the voting for the approval of this technical report can be found in the
report on voting indicated 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 62343 series, published under the general title Dynamic modules,
can be found on the IEC website.
The committee has decided 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
• amended.
A bilingual version of this publication may be issued at a later date.
