FIBRE OPTIC INTERCONECTING DEVICES
AND PASSIVE COMPONENTS –
FIBRE OPTIC PASSIVE POWER CONTROL DEVICES –

Part 1: Generic specification

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.
International Standard IEC 60869-1 has been prepared by subcommittee 86B: Fibre optic
interconnecting devices and passive components, of IEC TC 86: Fibre optics.
This fourth edition cancels and replaces the third edition, published in 1999, and constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– the terms and definitions were reconsidered;
– the requirement concerning the IEC Quality Assessment System was reconsidered;
– the clause concerning quality assessment procedures was deleted.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all the parts in the IEC 60869 series, under the general title Fibre optic
interconnecting devices and passive components – Fibre optic passive power control devices,
can be found on the IEC website.
Future standards will carry the new general title as cited above.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

FIBRE OPTIC INTERCONECTING DEVICES
AND PASSIVE COMPONENTS –
FIBRE OPTIC PASSIVE POWER CONTROL DEVICES –

Part 1: Generic specification



1 Scope
This part of IEC 60869 applies to fibre optic power control devices. These have all of the
following general features:
– they are passive in that they contain no opto-electronic or other transducing elements;
– they have two ports for the transmission of optical power and control the transmitted
power in a fixed or variable fashion;
– the ports are unconnectorized optical fibre tails or optical fibre pigtails with connectors.
This standard establishes generic requirements for the following passive optical devices:
– optical attenuator;
– optical fuse;
– optical power limiter.
Test and measurement procedures for the above products are described in IEC 61300-1, the
1
IEC 61300-2 series and the 61300-3 series [1,2,3] .
2 Normative references
