active upstream channel solutions. It is having built-in response correction,
which compensates the roll-off caused by diplex filters.

Note
The following specifications are valid for the module only. When it is installed into CXEamplifier, the return path performance will change, because there are losses at the signal
path before and after the module. The following values are typical values.
