Optional Modules
The tap accepts two types of optional plug-in modules:
Reverse Attenuator (RA) plug-in modules are available in 0, 3, 6, 9, and 12 dB
values. These plug-in modules are used to increase the reverse path tap loss
without significantly affecting forward tap loss. By selectively adding reverse
attenuation to taps of middle to lower value, reverse path tap losses can be made
more similar across the various values of taps used in an HFC network.

without significantly affecting forward tap loss. By selectively adding reverse
attenuation to taps of middle to lower value, reverse path tap losses can be made
more similar across the various values of taps used in an HFC network.
Inverse Equalizer (IEQ) modules are available in 3, 6, 9, and 12 dB values. These
plug-in modules are used to increase the forward path tap loss in a down-tilted
fashion, with greater loss at higher frequencies than lower frequencies, without
significantly affecting reverse tap loss. IEQ plug-in modules allow optimization
of tap output levels at tap locations closest to nodes and amplifiers with high-
level forward RF signals and significant up-tilt.

Reverse Attenuator
The reverse attenuator is a plug-in that can be installed in the field. For details, see
