Amplifier Characteristics
In the presence of line amplifiers , you need to ensure the
coexistence of the data network with these amps.
There are three types of amplifiers:
●
Active re turn path
: Line amplifiers with active return
channel are unidirectional, ie only amplify the signal from
the headend to the outlet (forward channel) or from TV
sockets to headend (return channel).
This prevents data communication because CoaxData is a
system that requires two-way communication between the
head and the socket on return path.
●
without return path
: Do not allow transmission of the
data signal on return path.
●
Pas s ive re turn path
: Allows pass of data signal on
bidirectional way, headend to outlet and viceversa.
Different solutions are presented below.
