Overview

EN 62148-12:2004 (equivalent to IEC 62148-12:2004) is a European/CENELEC standard that defines package and physical interface requirements for fibre optic laser transmitters with a coaxial RF connector. It specifies the mechanical, optical pigtail and electrical interfaces needed to ensure mechanical interchangeability of laser diode transmitter modules for printed-circuit-board (PCB) mounting and panel-mount applications in high‑bit‑rate optical communication systems.

Key topics and technical requirements

• Module type and classification: Defines these laser transmitter modules as Type 5 under the IEC 62148 series.
• Physical interface: Includes case outline and footprint drawings to enable consistent PCB and panel mounting.
• Pigtail and optical interface: Supports single‑mode fibres covered by IEC 60793-2-50 and ITU‑T Recommendations G.652 / G.653 / G.654; applicable optical connectors per IEC 60874 when a pigtail is terminated.
• Electrical interface:
  • A 7‑pin electrical connector arrangement (terminal numbering shown in the standard) for power, monitor and control signals.
  • A dedicated female coaxial RF connector (SMA‑compatible) as terminal 8 for RF drive signals; compatible connector standards referenced (IEC 60169‑15/16).
  • Pin‑function definitions provided for both direct‑modulation laser diode transmitters and electro‑absorption (EA) modulator integrated laser devices.
• Thermal and monitoring elements: Module designs anticipate inclusion of a thermo‑electric cooler (TEC) for temperature control and a photodiode (PD) for output power monitoring.
• Frequency range: RF frequencies relevant to these devices are considered in the document (RF defined here as ~10 kHz to 10 GHz).
• Drawings and normative references: The standard contains outline/footprint figures and normative references to related IEC and ITU‑T documents to ensure interoperability.

Applications and who uses it

EN 62148-12 is intended for:

• Laser diode and transceiver manufacturers designing pigtail laser transmitters with coaxial RF inputs.
• Telecom and datacom equipment designers integrating optical transmitters onto PCBs or panels.
• Contract manufacturers and PCB assemblers who need standardized mechanical footprints.
• Test labs and procurement teams validating mechanical and interface compliance for interoperability and replacement parts. Practical uses include high‑speed optical transmitter modules for metro, long‑haul and DWDM systems where standardized mechanical and RF interfaces simplify integration and field replacement.

Related standards

• EN/IEC 62148‑1 (General and guidance for package/interface standards)
• IEC 60169‑15 / IEC 60169‑16 (RF coaxial connectors: SMA, N)

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 ensur
