Optical circuit boards - Part 4-214: Interface standards - Terminated waveguide OCB assembly using a single-row thirty-two-channel symmetric PMT connector

IEC 62496-4-214:2020 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.

Cartes à circuits optiques - Partie 4-214: Normes d'interface - Terminaison d'un ensemble de cartes à circuits optiques à guides d'ondes utilisant un connecteur PMT symétrique de trente-deux canaux sur une seule rangée

IEC 62496-2-214:2020 définit les dimensions d’interface normalisées pour la terminaison d'un ensemble de cartes à circuits optiques (OCB: optical circuit board) à guides d'ondes (désigné plus simplement sous le terme "ensemble") qui utilise des connecteurs de trente-deux canaux sur une seule rangée pour des guides d’ondes en polymère connectés par un connecteur PMT symétrique.

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.

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.

amendments) applies.

3 Terms and definitions

For the purposes of this document, the terms and definitions given in IEC 62496-1 and

IEC 62496-4 apply.

addresses:

• 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.

the PMT body and the PMT cover.

Figure A.3 shows the positions of the channel ports at the end-face of an example of the

waveguide OCB. The origin point of the waveguide OCB is located at the midpoint of the bottom

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.

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.
