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, 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 62149-5 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
The text of this standard is based on the following documents:

INTRODUCTION
Fibre optic transceivers are used to convert electrical signals into optical signals and vice versa.
The optical performance criteria are generally well specified for a number of internationally
agreed applications areas such as ITU Recommendation TG.983.1 and IEEE 802.3. This
standard aims to assure inter-changeability in performance between fibre optic transceivers
for ATM-PON systems supplied by different manufacturers, but does not guarantee operation
between fibre optic transceivers.
Manufacturers using the standards are responsible for meeting the required performance
and/or reliability and quality assurance under a recognized scheme.

4 Classification
This part of IEC 62149 specifies the performance of optical transceivers with laser diode (LD)
driver circuits and clock and data recovery (CDR) ICs.
Fibre optic transceiver modules are classified into 5 types of forms according to the
combination of mating types of electrical and optical interfaces (for details see IEC 62148-1).
These include the following:
Type 1: Fibre optic connector interface with direct solderable type electrical terminals.
Type 2: Fibre optic connector interface with plug-in type electrical terminals.
Type 3: Fibre optic pigtail interface with direct solderable type electrical terminals.
Type 4: Fibre optic pigtail interface with plug-in type electrical terminals.
Type 5: Modules not classified into type 1 – type 4. (A typical example is a module that has
both electrical connectors and non-connector type terminals as an electrical
interface such as a coaxial connector for signal and lead terminals for the power
supply.)

5.4 Absolute limiting rating
Absolute limiting (maximum) ratings imply that no catastrophic damage will occur if the
product is subjected to these ratings for short periods, provided each limiting parameter is in
isolation and all other parameters have values within the normal performance parameters. It
should not be assumed that limiting values of more than one parameter could be applied at
any one time.
