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.

INTRODUCTION
At present there is no standard for reliability qualification for passive components with respect
to high power use. This has led to component manufacturers having to perform different set of
tests for various customers leading to higher cost. Additionally such non-standardized testing
has led to either over or under testing devices. The aim of this document is to mitigate these
issues, by establishing a common framework for reliability assurance at high optical power.
While there is no exact number beyond which the optical power is demarcated as high, power
exceeding 23 dBm (200 mW) of total input power is considered high.---------------------- Page: 7 ----------------------

Table 1 summarizes the tests for high power qualification test program that shall be
performed for passive devices and is intended for use in high optical power conditions.
The damp heat and temperature cycling tests (tests 1(a) and 2(a) in Table 1) are incorporated
in the basic qualification program in IEC 62005-9-1 for reliability qualification assurance.
When components are intended for use in high power applications,– high power exposure (tests 1(b) and 2(b) in Table 1) shall be performed on samples that
have first undergone damp heat and temperature cycling tests (tests 1(a) and 2(a)
respectively in Table 1), and– an endurance test (test 3 in Table 1) shall also be done to provide reliability qualification
assurance for passive components vis-à-vis high optical power.---------------------- Page: 9 ----------------------

4.2 Sample size
Sample sizes for the tests are defined in Table 1 of this document.
5 Apparatus
5.1 Source (S)
The source unit consists of an optical emitter, the means to connect to it, and the associated
drive electronics. A tunable light source (TLS), in which a specific output wavelength can be
tuned, may be chosen as the optical emitter. A TLS may consist of a tunable laser diode (LD)
and an optical amplifier, or be a fibre ring laser in order to get an efficient power to test.
Generally, the power and stability requirements of a test will necessitate that the means to
connect to the optical emitter be a fibre pigtail. The source shall be stable in output power and
wavelength/frequency over the measurement period. For dense wavelength divisionmultiplexing (DWDM) devices, the frequency uncertainty (instead of the wavelength
uncertainty) shall be less than half of the channel bandwidth. Unless otherwise stated in the
relevant specification, the source shall have the following characteristics:– wavelength uncertainty: ≤ ±5 nm (not DWDM devices);
– frequency uncertainty: ≤ ±6,3 GHz (DWDM devices of 25 GHz channel bandwidth);
≤ ±12,5 GHz (DWDM devices of 50 GHz channel bandwidth);
≤ ±25 GHz (DWDM devices of 100 GHz channel bandwidth);
– stability of responsivity: ≤ ±0,1 dB
5.2 Detector unit (D)
The detector unit consists of an optical detector, the means to connect to it, and the
associated electronics. The detectors shall have sufficient dynamic range to make the
necessary measurements and shall be linear over this range. The detectors shall be stable
over the measurement period and shall have an operational range consistent with the device
under test. The detectors can either use an adapter for the connection or accept bare fibre
properly cleaved. The detectors shall be capable of capturing all light emitted by the fibre tip
and/or connector plug. The detectors shall have the following characteristics:– linearity: ≤ ±0,1 dB
– stability: ≤ 0,05 dB
5.3 Environmental chamber
The test setup shall include an environmental chamber capable of producing and maintaining
the specified temperature and/or humidity.5.4 Data acquisition system (DAS)
Recording of the optical power readings at the optical detector may be done either manually
or automatically. Appropriate DAS shall be used where measurements are performedautomatically.
5.5 Temporary joints (TJ)
These are typically used in connecting the device under test to the test apparatus. Generally,
the optical power and stability requirements of a test will necessitate that the temporary joints
be fusion splices.---------------------- Page: 11 ----------------------
