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 62149-7 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.

Part 7: 1 310-nm discrete vertical cavity
surface emitting laser devices



1 Scope
This part of IEC 62149 covers the performance specification for 1 310-nm discrete vertical
cavity surface emitting laser (VCSEL) devices of transverse single-mode and multimode types
used for the fibre optic telecommunication and optical data transmission application in a form
of the VCSEL chips mounted on a substrate with wire bonding to their chips’ anode and
cathode terminals without any fibre pigtails. The performance standard contains a definition of
the product performance requirements together with a series of sets of tests and
measurements with clearly defined conditions, severities, and pass/fail criteria. The tests are
intended to be run on a “one-off” basis to prove any product’s ability to satisfy the
performance standard’s requirements.
A product that has been shown to meet all the requirements of a performance standard can
be declared as complying with the performance standard, but should then be controlled by a
quality assurance/quality conformance program.
Depending on the signalling speed and application areas, subcategorized specifications of the
1 310-nm discrete VCSEL are defined as shown in Table 1.

parameters. It should not be assumed that limiting value of more than one parameter can be
applied at any one time. The absolute maximum ratings of the subcategorized types, E1, E3,
E10, E40 BLR4, FC1GB, FC2GB, FC4GB and FC8GB for signalling speeds are listed in
Annexes A through D, depending on the transverse mode of the VCSELs between multimode

4.2 Operating environment
The operating environment of all the subcategorized types of the 1 310 nm VCSEL is
specified in Table 2.
