This European Standard was approved by CENELEC on 2011-05-16. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus,
the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy,
Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia,

Foreword
The text of document 100/1654/CDV, future edition 3 of IEC 60728-6, prepared by technical area 5,
Cable networks for television signals, sound signals and interactive services, of IEC TC 100, Audio, video
and multimedia systems and equipment, was submitted to the IEC-CENELEC parallel vote and was
approved by CENELEC as EN 60728-6 on 2011-05-16.
This European Standard supersedes EN 60728-6:2003.
EN 60728-6:2011 includes the following significant technical changes with respect to EN 60728-6:2003.
– The normative references were updated.
– The methods of measurement for optical power and return loss were substituted by
references to other standards.
– The method of measurement for polarization dependent loss was deleted.
– A method of measurement for carrier-to-crosstalk ratio (CCR) was added.
– The methods of measurement for CSO and CTB of optical amplifiers were substituted by a
method of measurement for microscopic gain tilt of optical amplifiers. This parameter can
be used for calculating the second order distortion of optical amplifiers according to the
method described in the new Annex B.
– New classes for optical transmitters and receivers have been defined.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2012-02-16
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-05-16
Annex ZA has been added by CENELEC.
