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.

Part 15: Discrete vertical cavity surface emitting laser packages

1 Scope and object
This part of IEC 62148 covers the physical dimension and interface specifications for the
discrete vertical cavity surface emitting laser (VCSEL) devices in optical telecommunication
and optical data transmission applications.
The object of this standard is to adequately specify the physical requirements of VCSEL
devices that will enable mechanical interchangeability of laser devices or transmitters
complying with this standard both at the printed circuit wiring board and for any panel-
mounting requirement.

4 Classification
This part of IEC 62148, which gives the physical dimension and interface specifications for
the discrete vertical cavity surface emitting laser devices, specifies the interface of types 1
and 3 modules with direct solderable type electrical terminals.
Fibre optic transceiver modules are classified into 5 types of forms according to the
combination of mating types of electrical and optical interfaces. Details are described in
IEC 62148-1. The 5 types are as follows:
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 are 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 Specification of the optical interface
5.1 General
The purpose of this standard is to adequately specify the physical requirements of a VCSEL
device that will enable mechanical interchangeability of laser devices or transmitters to this
specification both at the printed circuit board and for any panel mounting requirement.
5.2 Optical connector interface (type 1)
This standard applies to LC and SC optical connector interfaces. Detailed dimensions of the
optical receptacle are specified in IEC 61754-20 and IEC 61754-4-1.
5.3 Pigtail interface (type 3)
All optical fibres defined in IEC 60793-2 series and ITU-T Recommendation G.652 are
applicable.
All optical connectors defined in IEC 60874 series are applicable, if a pigtail is to be
terminated with an optical connector.
6 Specifications of electrical interfaces

Specifications for the electrical interface of VCSEL TO CAN, TOSA and VCSEL pigtail
packages are described as follows.
