Fibre-optic communication subsystem test procedures - Part 4-2: Installed cable plant - Single-mode attenuation and optical return loss measurement
IEC 61280-4-2: 2014 is applicable to the measurement of attenuation and optical return loss of installed optical fibre cable plant using single-mode fibre. This cable plant can include single-mode optical fibres, connectors, adapters, splices and other passive devices. The cabling may be installed in a variety of environments including residential, commercial, industrial and data centre premises, as well as outside plant environments. This standard may be applied to all single-mode fibre types including those designated by IEC 60793-2-50 as Class B fibres.The principles of this standard may be applied to cable plants containing branching devices (splitters) and at specific wavelength ranges in situations where passive wavelength selective components are deployed, such as WDMs, CWDM and DWDM devices. This standard is not intended to apply to cable plant that includes active devices such as fibre amplifiers or dynamic channel equalizers. This second edition cancels and replaces the first edition, published in 1999, and constitutes a technical revision. The main changes with respect to the previous edition are listed below: revision of optical time-domain reflectometer (OTDR) measurements; addition of optical return loss (ORL) measurements; addition of informative annexes on measurement uncertainties, OTDR configuration, test cord attenuation verification and spectral attenuation measurement. Keywords: measurement of attenuation and optical return loss of installed optical fibre cable plant using single-mode fibre

Fibre-optic communication subsystem test procedures - Part 4-2: Installed cabling plant - Single-mode attenuation and optical return loss measurements
IEC 62180-4-2:2024 is applicable to the measurements of attenuation and optical return loss of an installed optical fibre cabling plant using single-mode fibre. This cabling plant can include single-mode optical fibres, connectors, adapters, splices, and other passive devices. The cabling can be installed in a variety of environments including residential, commercial, industrial and data centre premises, as well as outside plant environments. This document is applicable to all single-mode fibre types including those designated by IEC 60793-2-50 as Class B fibres. The principles of this document can be applied to cabling plants containing branching devices (splitters) and at specific wavelength ranges in situations where passive wavelength selective components are deployed, such as WDM, CWDM and DWDM devices. This document is not intended to apply to cabling plants that include active devices such as fibre amplifiers or dynamic channel equalizers. This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of the equipment cord method; b) addition of test limit adjustment related to test cord grades; c) refinements on measurement uncertainties.
