Test conditions
Unless otherwise specified, all test methods are in accordance with the IEC 61300 series.
1 × 2 and 2 × 2 spatial switches 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 under standard atmospheric conditions, unless otherwise
stated. If the device is provided with an active temperature control, this shall be set at the setpoint specified by the manufacturer.
The requirements apply to every combination of input and output port.
Table 1 is intended to provide guidance on the wavelength ranges of the various spectral
bands. It is not intended to serve as a specification. Values of operating wavelength used in
performance verification shall be specified between the customer and supplier or shall be as
defined in the manufacturer’s specification.

British Standards Institution (BSI)
BSI is the national body responsible for preparing British Standards and other
standards-related publications, information and services.
BSI is incorporated by Royal Charter. British Standards and other standardization
products are published by BSI Standards Limited.
About us
Revisions
We bring together business, industry, government, consumers, innovators
and others to shape their combined experience and expertise into standards
-based solutions.
Our British Standards and other publications are updated by amendment or revision.
The knowledge embodied in our standards has been carefully assembled in
a dependable format and refined through our open consultation process.
Organizations of all sizes and across all sectors choose standards to help
them achieve their goals.
Information on standards
We can provide you with the knowledge that your organization needs
to succeed. Find out more about British Standards by visiting our website at
bsigroup.com/standards or contacting our Customer Services team or
Knowledge Centre.
Buying standards
You can buy and download PDF versions of BSI publications, including British
and adopted European and international standards, through our website at
bsigroup.com/shop, where hard copies can also be purchased.
If you need international and foreign standards from other Standards Development
Organizations, hard copies can be ordered from our Customer Services team.
Subscriptions
Our range of subscription services are designed to make using standards
easier for you. For further information on our subscription products go to
bsigroup.com/subscriptions.
With British Standards Online (BSOL) you’ll have instant access to over 55,000
British and adopted European and international standards from your desktop.
It’s available 24/7 and is refreshed daily so you’ll always be up to date.
You can keep in touch with standards developments and receive substantial
discounts on the purchase price of standards, both in single copy and subscription
format, by becoming a BSI Subscribing Member.
PLUS is an updating service exclusive to BSI Subscribing Members. You will
automatically receive the latest hard copy of your standards when they’re
revised or replaced.
To find out more about becoming a BSI Subscribing Member and the benefits
of membership, please visit bsigroup.com/shop.
With a Multi-User Network Licence (MUNL) you are able to host standards
publications on your intranet. Licences can cover as few or as many users as you
wish. With updates supplied as soon as they’re available, you can be sure your
documentation is current. For further information, email
