The LE1200 line
amplifier thanks to
it's modular style
and to the 3 different gain values
can be adapted to
each CATV
network.
DOCSIS3.1 compliant
forward path
DOCSIS3.1 compliant
return path
Optional connection to
Monitoring System

The automatic
controlled return
path ingress
switch, the
dividable high level
output, the module
defined breakpoint
frequency and the
optional AGC unit
as well as the
exchangeable tray
make the device
the best choice for
HFC solutions.
