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:
<300m/980ft
Amp. #1
IN
OUT
Amp. #60
IN
OUT
Example #1a: Daisy chain, total cable length max. 400m/1300ft
E.g., all amplifiers in one location or close to each other; NLB 60E in a
different location. Amp. #2

Amp. #3

<300m/980ft
Amp. #4

Amp. #60

Example #2a, Daisy chain, total cable length max. 400m/1300ft
E.g., one group of amplifiers joined by the NLB 60E; more amplifiers in
remote locations.

Example #2b, Dual daisy chain, total cable length max. 700m/2300ft
E.g., groups of amplifiers in separate locations without interconnection;
NLB 60E in a different location. Desirable where certain groups of
amplifiers can physically not be connected.

<100m/328ft total
cable length for links in
between amplifiers.
Example #1b: Closed loop, total cable length max. 700m/2300ft
E.g., all amplifiers in one location or close to each other; NLB 60E in a
different location. Closing the loop via "return" cable provides extra
redundancy and safer operation.

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.
