Guidelines for the routing and installation of network components:
•
As a rule, a minimum distance of 1m is prescribed with respect to electrical equipment, cabling
and other components that could produce electromagnetic and electrostatic fields. This includes
parallel runs of power or high-tension cables, circuit breakers etc.
•
The ISO-specifications allow for a maximum field strength of 2 V/m at frequencies between 10
kHz and 30 MHz and 5 V/m at frequencies between 30 MHz and 1 GHz.
•
Once a coaxial cable segment and all its components have been installed it is essential that the
worst-case reflections on the cable are determined. These should never exceed 7% of the injected
amplitude of the original signal. The reflection coefficient can be checked by means of a
reflectometer.
•
The overall loop resistance of a coaxial cable segment together with all its plugs and connectors
may not exceed a maximum of 5
Ω
.
•
The minimum radius of any bend in the cable may not be less than 21 cm. Where multiple bends
are anticipated the radius must not be less than 40 cm.
