Fibre optic active components and devices - Package and interface standards - Part 22: 25 Gbit/s directly modulated laser packages with temperature control unit

IEC 62148-22: 2023 defines the physical dimensions and interface specifications for directly modulated laser (DML) devices used in optical telecommunication and optical data transmission applications. The intent of this document is to adequately specify the physical requirements for DML devices so as to enable mechanical interchangeability of laser devices or transmitters complying with this document both at the printed circuit board and for any panel-mounting requirements.

Composants et dispositifs actifs fibroniques - Normes de boîtier et d'interface - Partie 22: Boîtiers pour laser à modulation 25 Gbit/s équipés d'une unité de régulation de température

IEC 62148-22: 2023 définit les dimensions physiques et les spécifications des interfaces pour les dispositifs laser à modulation directe (DML) utilisés dans les applications de télécommunications optiques et de transmission optique de données. L’objet du présent document est de spécifier de manière adéquate les exigences physiques des dispositifs DML de façon à permettre l’interchangeabilité mécanique des dispositifs laser ou des émetteurs conformes au présent document, tant au niveau de la carte de circuit imprimé que pour toute exigence de montage sur panneau.

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
