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 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 61290-6-1 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
It shall be read in conjunction with IEC 61291-1.
The text of this standard is based on the following documents:
FDIS Report on voting
86C/180/FDIS 86C/204/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.
Annexes A and B are for information only.

INTRODUCTION
As far as can be determined, this is the first International Standard on optical fibre amplifiers.
The technology of optical fibre amplifiers is quite new and still emerging, hence amendments
and new editions to this standard can be expected.
Each abbreviation introduced is explained in the text at least the first time it appears. However,
for an easier understanding of the whole text, a list of all abbreviations used is given in
annex A.

1 Scope and object
This part of IEC 61290 applies to optical fibre amplifiers (OFAs) using active fibres, containing
rare-earth dopants, presently commercially available.
The object of this standard is to establish uniform requirements for accurate and reliable
measurements, by means of the optical demultiplexer test method, of the following OFA
parameters, as defined in clause 3 of IEC 61291-1:
a) pump leakage to output;
b) pump leakage to input.
NOTE – All numerical values followed by (‡) are currently under consideration.
2 Normative reference
The following normative document contains provisions which, through reference in this text,
constitute provisions of this part of IEC 61290. At the time of publication, the edition indicated
was valid. All normative documents are subject to revision, and parties to agreements based
on this part of IEC 61290 are encouraged to investigate the possibility of applying the most
recent edition of the normative document indicated below. Members of IEC and ISO maintain
registers of currently valid International Standards.
