6 Test parameters for optical fibre cabling
6.1 General requirements
This standard applies the requirements of the test methods specified by ISO/IEC 14763-3 to information
technology cabling within the scope of this standard subject to the following:
a) the results shall be compared with relevant limits specified in EN 50173-1 or the applicable
application-specific standard;
b) the additional requirements of this clause shall be applied.
6.2 Channel and link attenuation
6.2.1 Treatment of measured results
6.2.2.1 All-silica optical fibre cabling terminated with connecting hardware having transmission
performance specified in EN 50173-1
See ISO/IEC 14763-3.
6.2.2.2 All-silica optical fibre cabling terminated with connecting hardware having transmission
performance other than that specified in EN 50173-1
The calculation of limits and measurement uncertainty shall take into account the performance of
reference and non-reference connectors provided within the relevant connector standards or
manufacturers’/suppliers’ information.
6.2.2.3 Other optical fibre cabling
The calculation of limits and measurement uncertainty shall take into account the performance of
reference and non-reference connectors provided within the relevant connector standards or
manufacturers’/suppliers’ information.
6.3 Inter-component distance
This standard extends the methods of ISO/IEC 14763-3 used to measure channel and link length to
determine inter-component distances.
Insert a new Clause 7
7 Inspection of optical fibre cabling and installed cabling components
This standard applies the requirements of ISO/IEC 14763-3 to the information technology cabling covered
by this standard.
Annex A
Replace Annex A by the following text and update the list of figures and tables in Contents:
Annex A
(informative)
XML Schema for portable field test equipment
A.1 General
Many types of portable field test equipment use proprietary software in order to view the results obtained.
This annex does not seek to replace such software. However, it may be desirable to view results from a
variety of test equipment using a common platform. Examples of such situations are where:
a) test results from different types of portable field test equipment are to be collated within a single
“database” for the purposes of review and assessment;
b) test results from one or more types of portable field test equipment are to be incorporated within third
party software documentation systems.
It has been common for test result data to be exported as text files (e.g. csv files). However, the level of
integration as described above from a range of text files has required significant additional data
management. In order to reduce the need for additional data treatment and to reflect the growth of web-
based solutions, the most applicable common platform is one that can be viewed with standardised
browser technology.
XML, a recognised data format specified by W3C (www.w3.org/XML/), is the most appropriate data
management solution. This annex defines the minimum data set and the applicable field names, in the
form of XML schema, for the export of data from the proprietary software used by suppliers of portable
field test equipment, or the test equipment itself, when testing cabling installed in accordance with
EN 50174 series of standards against the requirements of the applicable cabling application standard
(e.g. EN 50173-1).
Using the appropriate schema, the data format from a specific test result can be verified, prior to further
data formatting that allows the data to be viewed as HTML files, PDF files or by other XML files.
A.2 XML Schema
The XML file format allows structured data to be exchanged between applications, see Figure A.1.
An XSD file contains a set of rules that define the structure of an XML file. This annex describes an
XSD file (also available electronically) that describes the structure of the XML file format.
An XSLT file can be used to transform a XML file into another format. This is typically used to convert the
XML data into HTML so it can be viewed in a web browser.

Figure A.1 – Example of XML implementation
A.3 Data security
Unless appropriate steps are taken, the conversion of data from the native formats used by the suppliers
of portable field test equipment renders the data subject to subsequent modification. Appropriate third
party software such as “XML Signature” may be used to address the issue of data security. This is
outside the scope of this standard.
A.4 XML Schema – Test result envelope
Figure A.2 shows the overall schema design for the XML data format to be used to export test results for
all balanced and optical fibre cabling.
