FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61977 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/1603/FDIS 86B/1637/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 3.
The QC number that appears on the front cover of this publication is the specification number
in the IEC Quality Assessment System for Electronic Components (IECQ).
The committee has decided that the contents of this publication will remain unchanged until
2008. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

INTRODUCTION
This standard is divided into three elements.
The first element, made up of clauses 1 to 3, contains general information which pertains to
this standard.
The second element, consisting of clause 4, Requirements, contains all requirements which
should be met by fibre optic filters covered by this standard. Requirements for classification,
the IEC specification system, documentation, materials, workmanship, quality, performance,
identification, and packaging are covered.
The third element, composed of clause 5, Quality assessment procedures, contains all of the
procedures which must be followed for proper quality assessment of products covered by this
standard.

FIBRE OPTIC FILTERS –
Generic specification
1 Scope
IEC 61977 applies to the family of fibre optic filters. These components have all of the
following general features:
– they are passive for the reason that they contain no optoelectronic or other transducing
elements which can process the optical signal launched into the input port;
– they modify the spectral intensity distribution in order to select some wavelengths and
inhibit others;
– they are fixed, i.e. the modification of the spectral intensity distribution is fixed and can
not be tuned;
– they have a maximum of two ports for the transmission of optical power; the ports are
optical fibre or optical fibre connectors;
– they differ according to their characteristics. They can be divided into the following
categories:
• short-wave pass (only wavelengths lower than or equal to a specified value are
passed);
• long-wave pass (only wavelengths greater than or equal to a specified value are
passed);
• band-pass (only an optical window is allowed);
• notch (only an opt
