ROADMAP OF OPTICAL CIRCUIT BOARDS AND
THEIR RELATED PACKAGING TECHNOLOGIES
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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 62658, which is a technical report, has been prepared by IEC technical committee 86:
Fibre optics.
The text of this technical report is based on the following documents:
Enquiry draft Report on voting
86/442/DTR 86/453/RVC
Full information on the voting for the approval of this technical report can be found in the
report on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

ROADMAP OF OPTICAL CIRCUIT BOARDS AND
THEIR RELATED PACKAGING TECHNOLOGIES
1 Scope
This Technical Report covers the roadmap of optical circuit boards, and its related packaging
technologies including optical circuit board connectors and optical modules on boards.
2 General
2.1 Background of optical packaging technology road map
The volume of network traffic is dramatically increasing due to the amount of data being
captured, processed, conveyed and stored as digital information. This information is
generated from many sources, including critical business applications, email communications,
the Internet and multimedia applications which have collectively fuelled an increase in
demand for data networking and storage capacity. In addition, the proliferation of media rich
applications, such as digital music and video sharing services is fuelling a concurrent
increase in data processing in data centres [1] . The growth in network traffic attributed to
personalized content is 20 % per month, giving rise to a doubling of network traffic every
1,5 years. However, this is out of step with the input/output (I/O) performance or I/O
throughput of servers, which doubles every 2 years. Therefore, there is an increasing gap
between the performance evolution of network equipment such as servers, and the growth in
network traffic (Figure 1) [2].

Figure 1 – Data transmission speed and capability trends
for network traffic and server systems [2]
In general, system power consumption will increase as the volume of internet traffic expands.
By 2020, power consumption in network routers in Japan will reach the gross power
generation of Japan in 2005. An energy saving by 3 to 4 orders of magnitude in network
router technology is required in 2030 to meet the stipulated targets in the Kyoto protocol [3]
(Figure 2).
In addition, the bandwidth and density requirements for interconnects within high-performance
computing systems are becoming unmanageable, due to increasing chip speeds, wider buses
and larger numbers of processors per system [4]. The increase in system bandwidth and
density required to satisfy this demand would impose unmanageable cost and performance
burdens on future data networking and storage technologies.
An alternative to the current electrical printed circuit board (PCB) interconnect technology is
required across multiple high-speed application spaces to mitigate this common trend. Optical
interconnects are expected to bridge the performance gap between network hardware and
traffic, and give rise to a reduction in hardware power consumption while increasing
bandwidth density by over two orders of magnitude.
