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.

IEC 61753-091-02 has been prepared by subcommittee 86B: Fibre optic interconnecting

devices and passive components, of IEC technical committee 86: Fibre optics. It is an

International Standard.

This first edition cancels and replaces IEC 61753-091-2 published in 2012. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to

IEC 61753-091-2:
a) change of title adding the 3-port incompletely circulated type;

b) harmonization of terms and definitions with those in IEC 61977 and IEC TS 62627-09;

c) harmonization of test items and their conditions with IEC 61753-1:2018 and
IEC 61753-1:2018/AMD1:2020.

1 Scope

This part of IEC 61753 contains the minimum test and measurement requirements and

severities which a fibre optic circulator as specified by IEC 62077 is expected to satisfy in order

to be categorized as meeting the requirements of circulators used in controlled environments

as specified in IEC 61753-1:2018 and IEC 61753-1:2018/AMD1:2020. The requirements cover

non-connectorized single-mode fibre 3-port incompletely circulated type optical circulators for

category C used in controlled environments.
