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.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC-PAS 61753-088-2 has been processed by subcommittee 86B: Fibre optic interconnecting
devices and passive components, of IEC technical committee 86: Fibre optics.
The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document

Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned may transform it into an International Standard.
A list of all parts of the IEC 61753 series, under the general title Fibre optic interconnecting
devices and passive components – Performance standard can be found on the IEC website.
This PAS shall remain valid for an initial maximum period of 3 years starting from the
publication date. The stability date may be extended for a single 3-year period, following
which it shall be revised to become another type of normative document, or shall be
withdrawn.

FIBRE OPTIC INTERCONNECTING DEVICES AND
PASSIVE COMPONENTS PERFORMANCE STANDARD –

Part 088-2: Non-connectorised single-mode fibre optic LAN WDM devices
with channel spacing of 800 GHz for category C –
Controlled environments
1 Scope
This Publicly Available Specification (PAS) contains the minimum initial test and measurement
requirements and severities which a non-connectorised single-mode fibre optic Local Area
Network Wavelength Division Multiplexing (LAN WDM) device with channel spacing of
800 GHz needs to satisfy in order to be categorised as meeting the requirements of category C
– Controlled environments, as defined in Annex A of IEC 61753-1. The applications of LAN
WDM adevices are optical MUX and DEMUX for 100GBASE-LR4 (required operating range of
2 m to 10 km) and 100GBASE-ER4 (required operating range of 2 m to 30 km) defined in
IEEE Draft P802.3ba, as shown in Annex D. The requirements cover both an integrated 1 × 4
LAN WDM device and an individual 1 × 2 LAN WDM device for cascaded module construction.
