Overview

IEC 62148-17:2023 is an international standard published by the International Electrotechnical Commission (IEC), focusing on the physical interface specifications for fibre optic transmitter and receiver components equipped with dual coaxial RF connectors. This latest 2023 edition replaces the original 2013 edition, providing a technical revision that aligns with evolving industry practices and connector technologies. The standard defines consistent package designs, electrical interfaces, and electromagnetic compatibility (EMC) requirements for enhanced interoperability and reliability in fibre optic communication systems.

Key Topics

• Dual Coaxial RF Connectors: Specifies the use of dual coaxial connectors for both transmitter and receiver components, including detailed assignments for electrical terminals.
• Physical Packaging: Defines the package outline and recommended printed circuit board (PCB) footprint layouts to ensure uniform assembly and integration.
• Electrical Interface: Details electrical terminal numbering, function definitions, and the application of SMPM (sub-miniature push-on miniature) connectors as per IEC 61169-60.
• Electromagnetic Compatibility: Mandates EMC compliance in alignment with IEC 61000 series to ensure components meet emission and immunity standards.
• Normative References: Incorporates references to related IEC standards such as IEC 61754 for fibre optic connector interfaces, IEC 62007-1 for optoelectronic device terminology, and replaces the withdrawn IEC 60874-1.
• Classification: Categorizes the components as type 7 following IEC 62148-1 specifications for active fibre optic devices.

Applications

IEC 62148-17:2023 is critical for manufacturers, designers, and integrators of fibre optic active components ensuring:

• Standardized Package and Interfaces
  Facilitates the design of transmitter and receiver modules with uniform footprints and connector compatibility, promoting interoperability across suppliers and optical systems.

• High-Frequency RF Signal Transmission
  Supports high-performance optical transmitters and receivers in telecommunications, data centers, and high-speed networking where dual coaxial RF connectors provide robust signal integrity.

• Electromagnetic Interference Mitigation
  Helps develop components that comply with stringent EMC requirements, assuring stable operation in environments susceptible to electromagnetic disturbances.

• Component Interchangeability
  Enables system engineers to select components from different manufacturers without redesigning interfaces or PCBs, reducing development time and costs.

• Advanced Optical Systems
  Particularly relevant for systems employing external modulators with laser diodes (EMwL) and photodiode (PD) receivers, facilitating precise electrical and optical interfacing.

Related Standards

To complement IEC 62148-17:2023, the following IEC standards are essential for comprehensive understanding and implementation of fibre optic active components:

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.
IEC 62148-17 has been prepared by subcommittee 86C: Fibre optic systems and active
devices, of IEC technical committee 86: Fibre optics. It is an International Standard.
This second edition cancels and replaces the first edition published in 2013. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) IEC 61169-60 was added as a normative reference for SMPM connectors;
b) normative reference IEC 60874-1 (withdrawn) was replaced by IEC 61754 (all parts);
c) a reference to the terms and definitions of IEC 62007-1 was added in Clause 3;
d) a new column “Typical” was added to the tables in Figure 2 and Figure 3 to clarify the
meaning of all listed values.
This standard is to be read in conjunction with IEC 62148-1.
