Test

Unless otherwise specified, all test methods are in accordance with the IEC 61300 series.
Each test defines the number of samples to be evaluated. The samples used for each test are
intended to be previously unstressed new samples but may also be selected from previously
used samples if desired. The plug-pigtail style samples shall be terminated onto single-mode
fibres as per IEC 60793-2-50 category B1.1, B1.3 or B6 in either coated fibres (primary and
secondary) or reinforced cable format. For plug-receptacle style samples fibres as per
IEC 60793-2-50 category B1.1, B1.3 or B6 shall be used. All measurements shall be carried
out at standard atmosphere condition defined in IEC 61300-1, unless otherwise stated.
All tests shall be carried out over the operating wavelength range: the signal wavelength
ranges of 1 260 nm to 1 360 nm, 1 480 nm to 1 500 nm and 1 550 nm to 1 560 nm, and the
OTDR wavelength of 1 620 nm to 1 630 nm or 1 645 nm to 1 655 nm, unless otherwise
specified.
NOTE 1 310 nm, 1 490 nm and 1 550 nm are the nominal or centre wavelengths, stated for the ranges 1 260 nm
to 1 360 nm, 1 480 nm to 1 500 nm and 1 550 nm to 1 560 nm as defined in ITU-T Recommendations G.983.3 [2],
G.984.2 [3] and IEEE standard 802.3ah-2004 [4].

Test report

Fully documented test reports and supporting evidences shall be prepared and be available
for inspections as evidence that the tests have been carried out and complied with.

6

Reference components

The test for these components does not require the use of reference components.

Performance requirements

7.1

Dimensions

Dimensions shall comply with either an appropriate IEC interface standard or with those given
in appropriate manufacturers drawings, where the IEC interface standard does not exist or
cannot be used.
7.2

Annex B
(informative)
General information of OTDR reflecting devices
One possible solution for OTDR reflecting devices is the use of a chirped FBG filter
embedded in the connector. The other possible solution is the use of a thin film filter (TFF).
The chirped FBG and the TFF reflect OTDR signals and block ONU devices from receiving the
same.
The OTDR reflecting devices dimensions are as follows:

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
