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.

International Standard IEC 61754-32 has been prepared by subcommittee 86B: Fibre optic

interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.

The text of this standard is based on the following documents:
FDIS Report on voting
86B/4005/FDIS 86B/4021/RVD

Full information on the voting for the approval of this standard 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 website under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be

Part 32: Type DiaLink connector family
1 Scope

This part of IEC 61754 defines the standard interface dimensions for the type DiaLink family

of connectors.
2 Normative references

The 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.
There are no normative references in this document.
3 Description

The parent connector for the type DiaLink connector family is a simplex connector which is

characterized by a 1,25 mm nominal ferrule diameter. It includes a push-pull coupling

mechanism, which is spring-loaded relative to the ferrule in the direction of the optical axis.

To provide adequate contact force, one of the parts containing the ferrule is spring-loaded.

The other part contains a fixed ferrule. The optical alignment mechanism of the connectors is

a resilient sleeve style and is attached directly to the fixed ferrule interface.

Drawings and dimensions provided consist of those minimum features that are functionally

critical during the mating and unmating sequences of counterpart components.
4 Interfaces

This document defines the standard interfaces for the type DiaLink connector family.

This document contains the following standard interfaces:
IEC 61754-32-1 Fixed ferrule plug connector PC-interface (plug connector)

IEC 61754-32-2 Spring-loaded ferrule plug connector PC-interface (socket connector)

IEC 61754-32-3 Fixed ferrule plug connector interface – APC 8° (plug connector)

IEC 61754-32-4 Spring-loaded ferrule plug connector interface – APC 8° (socket connector)

The document interfaces given in Table 1 are intermateable.

The connector alignment feature is a resilient (split) alignment sleeve. The feature shall accept a pin gauge to

a distance corresponding to the optical reference plane with a force of 1,0 N to 2,5 N under the condition that

another pin gauge is inserted into the feature from the other side until both pin gauges butt against each other.

The pin gauge shall be according to Figure 3.

These dimensional requirements apply to the finished ferrule, after all polishing procedures have been

completed.

Dimension BI is the radius of the polished ferrule end face according to the relevant optical interface

IEC 61755 (all parts).

Dimension EA is defined as an angle between two planes: one plane, plane A, passes through the axis of the

ferrule and the axis of symmetry of the key of the angled end face connector plug. The other plane, plane B,

passes through the axis of the ferrule and the plane normal to the angled PC reference plane.

Dimension 8,65 is given for a plug end face when not mated. The ferrule is movable by a certain axial

compression force, with direct contacting end face, and therefore dimension B is variable. Ferrule compression

force shall be 5,0 N to 8,5 N when the position of the optical datum target, dimension 8,65, is moved to the range

9 mm to 9,15 mm. Forces are for buffered fibre only, different cord constructions can result in higher forces, see

IEC 60794-2-50.

The push-pull mechanism shall unlock when the connector is pulled with a force > 12 N.

The radius AR and BR may be smaller when using bend insensitive fibre (e.g. B6 fibre).

This dimension results from the sum of BR and the rigid part of the connector. This dimension could therefore be

reduced when reducing BR.
