Overview

IEC TS 62661-2-1:2013 specifies product-level guidelines for an optical backplane architecture that uses optical fibre circuit boards and multi-core right angle optical connectors. The technical specification addresses an optical backplane built with low bending loss multimode fibres (referred to as low-loss RAO) to link daughter boards to the backplane. It defines physical dimensions, connection arrangements, connector mounting and classification, and test/qualification requirements for reliable optical interconnects in sub-rack systems.

Key topics and requirements

• Product definition and dimensions
  • Designed to fit IEC 60297-3-101 sub-racks; a single optical backplane occupies 100 mm (height) × 420 mm (width).
  • Supports up to 14 front (daughter) boards with a 6HP pitch (30.48 mm).
  • Uses optical fibre boards (per IEC 62496-3-1) with low bending loss multimode fibre.
• Connection architecture
  • Defines slot numbering and a dual‑star optical connection model between daughter board A and daughter board B.
  • Uses compact right‑angled optical board (CRO) connectors (new RAO type specified in Annex B) for multi‑core right angle optical connections.
• Mechanical and dimensional requirements
  • Detailed requirements for connector mounting positions on backplane and daughter boards, optical wiring areas, and interconnection conditions.
• Optical, mechanical and environmental tests
  • Optical performance: attenuation, return loss, optical propagation delay (referenced IEC procedures such as IEC 61300-3-4, IEC 61300-3-6, IEC 60793-1-22).
  • Mechanical: mating durability, vibration, shock (IEC 61300 series).
  • Environmental and reliability: cold, dry heat, damp heat, temperature endurance and change of temperature.
  • Test sample sizes, methods, sequence and pass/fail criteria are specified for product qualification.
• Annexes
  • Annex A: mounting an optical backplane to ATCA zone 3 (application-specific dimensional guidance).
  • Annex B: detailed CRO connector specification and interfaces for the multi-core right angle optical connectors.

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. In
exceptional circumstances, a technical committee may propose the publication of a technical
specification when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide
whether they can be transformed into International Standards.
IEC 62661-2-1, which is a technical specification, has been prepared by IEC technical
committee 86: Fibre optics.

4.2 Dimension of optical wiring on optical backplane
The area for optical wiring and the position of optical connectors mounted on an optical
backplane are shown in Figure 2. The reference position on an optical backplane is
determined first; the dimensions to other parts on the backplane are determined by the
distance from the reference position. The position of an optical fibre as connected to an
optical connector is defined by the connecting position of an MT ferrule of a low-loss RAO

– 10 – TS 62661-2-1 © IEC:2013(E)
connector specified by IEC 61754-25. The position of a ferrule is specified by the centre of
the ferrule.
The optical wiring pattern is formed on the optical fibre board at the connecting position
corresponding to the holes for fibres in an MT ferrule. The size of the optical fibre board is
420 mm × 100 mm. The optical wiring pattern is formed on the board avoiding the positions to
which low-loss RAO connectors are to be mounted. The positions for electric connectors are
designed based on the reference position on the optical backplane when both optical and
electric connectors are needed on the board.

4.4 Mounting position of connectors on optical backplane
Mounting condition of the low loss RAO connectors on an optical backplane is shown in
Figure 4. Positions of the holes to mount the RAO connectors are defined by the relative
distance from the reference position on the optical backplane. The area for mounting of
connectors is also defined as the area C in Figure 4. Optical fibres are not allowed to be
installed in this area. An actual example of the relation of distance from the reference point of
the optical backplane to the position of electric connectors is described in Annex A.
4.5 Mounting position of connectors on daughter board
Mounting condition of the low loss RAO connectors on a daughter board is shown in Figure 5.
The highest hole position in the mounting holes of the RAO connector to be mounted on the
highest position on the daughter board is defined as the reference position on the daughter
board. This position shall also be used as the reference position of an electrical/electronic
connector to be mounted. The distance to the edge of a daughter board is approximately
illustrated in the Figure (distance shown in the figure with parentheses). An actual example of
mounting of RAO connectors to a daughter board is given in Annex A.
