78 FOREWORD
79 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
80 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
81 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
82 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
83 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
84 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
85 in the subject dealt with may participate in this preparatory work. International, governmental and non-
86 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
87 with the International Organization for Standardization (ISO) in accordance with conditions determined by
88 agreement between the two organizations.89 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
90 consensus of opinion on the relevant subjects since each technical committee has representation from all
91 interested IEC National Committees.92 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
93 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
94 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
95 misinterpretation by any end user.96 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
97 transparently to the maximum extent possible in their national and regional publications. Any divergence
98 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
99 the latter.100 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
101 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
102 services carried out by independent certification bodies.103 6) All users should ensure that they have the latest edition of this publication.
104 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
105 members of its technical committees and IEC National Committees for any personal injury, property damage or
106 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
107 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
108 Publications.109 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
110 indispensable for the correct application of this publication.111 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
112 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
113 IEC 62148-22 has been prepared by subcommittee 86C: Fibre optic systems and active
114 devices, of IEC technical committee 86: Fibre optics. It is an International Standard.
115 The text of this International Standard is based on the following documents:Draft Report on voting

133 INTRODUCTION
134 Fibre optic laser devices are used to convert electrical signals into optical signals. This
135 international standard covers the physical dimensions and interfaces for directly modulated
136 laser (DML) packages which are intended to be applied to 25 Gbit/s transceivers.

143 1 Scope
144 This part of IEC 62148 defines the physical dimensions and interface specifications for
145 directly modulated laser (DML) devices used in optical telecommunication and optical data
146 transmission applications.147 The intent of this document is to adequately specify the physical requirements for DML
148 devices so as to enable mechanical interchangeability of laser devices or transmitters
149 complying with this document both at the printed circuit board and for any panel-mounting
150 requirements.151 2 Normative references
152 The following documents are referred to in the text in such a way that some or all of their
153 content constitutes requirements of this document. For dated references, only the edition
154 cited applies. For undated references, the latest edition of the referenced document (including
155 any amendments) applies.156 IEC 60793-2-50, Optical fibres – Part
