Information technology - Implementation and operation of customer premises cabling - Part 3: Testing of optical fibre cabling
ISO/IEC 14763-3:2024 specifies systems and methods for the inspection and testing of installed optical fibre cabling designed in accordance with premises cabling standards including the ISO/IEC 11801 series. The test methods refer to existing standards-based procedures where they exist.
This third edition cancels and replaces the second edition published in 2014 and Amendment 1:2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) removal of plastic fibre testing;
b) addition of testing of MPO cabling;
c) restructuring of the content;
d) addition of end-to-end link LSPM testing;
e) addition of MPTL LSPM testing;
f) addition of measurement uncertainty for all measurement methods;
g) introduction of normative inspection for cleanliness to align with the ISO/IEC 11801 series;
h) testing will support SM ranges up to 10 km;
i) introduction of new test limits for connector attenuation against reference connector;
j) introduction of description of reference connectors;
k) introduction of recommended cleaning methods.
