1 Scope
This European Standard defines outdoor multi-pair/quad cables for use in high bit rate
telecommunication networks with their relative definitions and requirements.
It covers radially water blocked cables, with an overall screen, with performances up to 60 MHz, to be
used in outdoor networks intended to connect the broadband outside plant to the individual customer
premises with a maximum recommended length of connection of 1 km.
The electrical, environmental, mechanical and transmission performance characteristics of the cables,
related to their reference test methods, are detailed.
