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.

1 Scope
This part of IEC 62496 defines the standard interface dimensions for a terminated waveguide
optical circuit board (OCB) assembly (referred to simply as "assembly") using single-row thirty-
two-channel connectors for polymer waveguides connected with a symmetric PMT connector.
2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies.
For undated references, the latest edition of the referenced document (including any
amendments) applies.IEC 62496-1, Optical circuit boards – Part 1: General
IEC 62496-4, Optical circuit boards – Part 4: Interface standards – General and guidance
3 Terms and definitionsFor the purposes of this document, the terms and definitions given in IEC 62496-1 and
IEC 62496-4 apply.ISO and IEC maintain terminological databases for use in standardization at the following
addresses:• IEC Electropedia: available at http://www.electropedia.org/
• ISO Online browsing platform: available at http://www.iso.org/obp
4 Description
The assembly is an assembly comprised of a symmetric PMT connector and a thirty-two-
channel waveguide OCB. The symmetric PMT connector is a rectangular connector having the
same outer dimensions as the type MT connector specified in IEC 61754-5. The symmetric PMT
connector is aligned using alignment pins and is normally secured by the use of a latching
spring and mates with the type MT connector as shown in Figure 1. Dimensions of components
for the assembly are shown in Annex A. The waveguide OCB comprises a planar light-guide
consisting of a core and cladding material appropriate to transmit light as the operational
wavelengths require, the light-guide being supported on a substrate. Preferably, the substrate
will be flexible in order to accommodate compliance to the MT connector. The cores of the
waveguide OCB are aligned with the optical fibres of the MT connector after mating using two
guide pins and a clamp spring. Dimensions of a single-row thirty-two-channel MT ferrule are
shown in Annex B. This symmetric PMT connector is not intermateable with the standard 16
channel MT ferrules.---------------------- Page: 7 ----------------------

of the outline of the waveguide OCB, as shown in Figure A.3. Table A.2 gives dimensions of
the positions of the example of thirty-two channel ports.---------------------- Page: 13 ----------------------

Dimensions of an example of a single-row thirty-two-channel MT ferrule
The MT connector intermateable with a single-row thirty-two-channel symmetric PMT connector
is not defined yet. Figure B.1 and Table B.1 show an example of a single-row thirty-two-channel
MT ferrule used for the customized MT connector. Figure B.2 and Table B.2 show an example
of the interface view and fibre hole positions, respectively. Fibre types for the customized MT
connector are those with a cladding, for example, of Φ80 µm and a coating of Φ125 µm.
