Description / Abstract:
This part of IEC 61280 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.
