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 61753-381-2 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/3954/FDIS 86B/3969/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 2.

A list of all parts in the IEC 61753 series, published under the general title Fibre optic
interconnecting devices and passive components – Performance standard, can be found on
the IEC website.
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website 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

Part 381-2: Cyclic arrayed waveguide grating –
Category C (controlled environment)



1 Scope
This part of IEC 61753 contains the minimum initial test and measurement requirements and
severities which a Gaussian-passband-profile cyclic arrayed waveguide grating (AWG) for
single-mode and bidirectional transmission systems satisfies in order to be categorised as
meeting the requirements of IEC 61753-1 for category C (controlled environment). This
standard pertains to wavelength division multiplexing (WDM) network with multiple spectral-
band usage. This standard covers the requirements of cyclic AWG devices with free spectral
range (FSR) characteristics to ensure multiple spectral bands transmission performance, with
single-mode non-connectorised pigtails and no electric circuit board.

Note 1 to entry: This note applies to the French language only.
4 Test conditions
All test methods are in accordance with the IEC 61300 series. Each test defines the number
of samples to be evaluated. DWDM devices used for each test are intended to be previously
unstressed new samples but may also be selected from previously used samples if desired.
All measurements shall be carried out at normal room conditions, unless otherwise stated. If
the device is provided with an active temperature control, this shall be set at the set-point
specified by the manufacturer.
All tests are to be carried out to validate performance over the required operating wavelength
range. As a result, single or multiple spectral bands may be chosen for the qualification and
differing target specifications may be assigned to each spectral band.
5 Test report
Fully documented test reports and supporting evidence shall be prepared and shall be
available for inspection as evidence that the tests have been carried out and complied with.
Cyclic-AWG

6 Reference components
The testing for DWDM devices does not require the use of reference components.
7 Performance requirements
7.1 Dimensions
Dimensions shall be in accordance with those given in appropriate manufacturers’ drawings.
7.2 Test details and requirements
Table 1 specifies the optical perfomance and related test methods for Gaussian passband
profile.
Table 2 defines the environmental and mechanical performance requirements and test
methods.
The operating wavelengths, unless otherwise specified, shall be in accordance with ITU
Recommendation G.692, G.694.1 and G.698.3 (Frequency Spacing). Where devices with
wavelength spaced channels have to be considered the conversion should refer to vacuum
wavelength.
The value of "c" (speed of light in vacuum) that should be used for converting between
8
frequency and wavelength is 2,997 924 58 × 10 m/s.
Conformance to this standard requires demonstration of the ability to meet both the relevant
optical and the environmental parameters.
For connectorized components, the connector performances shall be in accordance with
IEC 61753-021-2.
