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.

INTRODUCTION
A wavelength selective switch (WSS) is a dynamic module, which is mainly used in a
reconfigurable optical add drop multiplexer (ROADM) system to switch all wavelength signals
to their respective required output port in dense wavelength division multiplexing (DWDM)
networks. The WSS module has one input port and a plurality of output ports (i.e. 1 x N WSS)
and can be used reversely, such as N input ports and one output port, depending on its
application. It is electrically controlled with software, which directs each wavelength signal
among an input DWDM signal from one input port to the required output port for each
wavelength signal.

1 Scope
This part of IEC 62343 describes and provides specifications for a software and hardware
interface for the 1 x 9 wavelength selective switch.
These switches can be controlled by resident firmware with this interface. This standard
addresses the configuration and function to control a WSS. This interface is intended to
enable a user or host to retrieve the switch status and/or adjust relevant switch and
attenuation settings.
