Part 1: Generic specification
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 60876-1 has been prepared by subcommittee SC86B: Fibre optic
interconnecting devices and passive components, of IEC technical committee 86: Fibre optics.
This fourth edition cancels and replaces the third edition published in 2001. It constitutes a
technical revision. The changes with respect to the previous edition are to remove quality
assessment procedures and to reconsider definitions.

3 Terms and definitions
For the purposes of this part of IEC 60876, the definitions given in IEC 60050-731 apply,
together with the following definitions.
3.1 Basic terms and definitions
3.1.1
port
optical fibre or fibre optic connector attached to a passive component for the entry and/or exit
of optical power
3.1.2
transfer matrix
optical properties of a fibre optic switch can be defined in a n × n matrix of coefficients (n is the
number of ports)
Note 1 to entry: The T matrix represents the on-state paths (worst-case transmission) and the T° matrix represents
the off-state paths (worst-case isolation).
3.1.3
transfer coefficient
element t or t° of the transfer matrix
ij ij
Note 1 to entry: Each transfer coefficient t is the worst-case (minimum) fraction of power transferred from port i to
ij
port j for any state with path ij switched on. Each coefficient t° is the worst-case (maximum) fraction of power
ij
transferred from port i to port j for any state with path ij switched off.
3.1.4
logarithmic transfer matrix
a = –10 log t
ij ij
where
is the optical power reduction in decibels out of port j with unit power into port i, i.e.
a
ij
t is the transfer coefficient.
ij
Note 1 to entry: Similarly, for the off state, a° = –10 log t°
ij ij
3.2 Component definitions
3.2.1
optical switch
passive component processing one or more ports which selectively transmits, redirects or
blocks optical power in an optical fibre transmission line
3.2.2
switch state
particular optical configuration of a switch, whereby optical power is transmitted or blocked
between specific ports in a predetermined manner
3.2.3
actuation mechanism
physical means (mechanical, electrical, acoustic, optical, etc.) by which a switch is designed to
change between states
---------------------- Page: 13 ----------------------
SIST EN 60876-1:2012
– 8 – 60876-1 IEC:2012(E)
3.2.4
actuation energy
input energy required to place a switch in a specific state
3.2.5
latching switch
switch that maintains its last state and specified performance level when the actuation energy
which initiated the change is removed
3.2.6
non-latching switch
switch that reverts to a home state or undefined state when the actuation energy which initiated
a change is removed
3.2.7
blocking
inability to establish a connection from a free input port to a free output port due to the
existence of some other established connection
Note 1 to entry: Blocking and various degrees of non-blocking operation functionalities are of various types.
“Strict-sense non-blocking” refers to a switch matrix in which it is always possible to establish a connection between
any free input port and any free output port irrespective of previously established connections.
“Wide-sense non-blocking” refers to a matrix in which it is always possible to establish a desired connection
provided that some systematic procedure is followed in setting up connections. Some multistage switching
architectures fall into this category.
“Rearrangeably non-blocking” refers to a switch matrix in which any free input port can be connected to any free
output port provided that other established connections are unconnected and then reconnected as part of making
the new connection.
3.2.8
magneto-optic effect switch
MO switch
optical switch which uses the magneto-optic effect (phenomenon of polarization state change
in transmitted light and reflected light due to a magnetic field)
3.2.9
mechanical switch
optical switch, which realises the switching function by driving of the movable part
3.2.10
micro-electromechanical system switch
MEMS switch
optical switch using MEMS technology, as defined in IEC 62047-1

Note 1 to entry: It is the fraction of input power that is returned from the input port of a passive component and is
defined as follows:
RL = –10 log (P /P )
i refl i
where
P is the optical power launched into the input port, and
i
P is the optical power received back from the same port.
refl
