7 OPERATION AND PERFORMANCE
7.7.3 NomadLink network cable lengths
In situations where the amplifiers and the NLB 60E
will be positioned in different locations at some
distance from each other, or where groups of
amplifiers within a single subnet with up to 60 units
will be installed with a distance in between, these
general rules may be considered:
Below are typical examples of NomadLink network
setups:
Example #1a: Daisy chain, total cable length max. 400m/1300ft

Rule 1:
•
The maximum cable length in between any two
devices may not exceed 300 meters / 980 feet.
•
Rule 2:
In a non-closed-loop daisy-chained subnet the
total maximum cable length is 400 meters /
1300 feet.
Rule 3:
•
In a closed-loop subnet the total maximum
cable length is 700 meters / 2300 feet.
