SYSTEM GAIN
The system gain of the Fusion Wideband defaults to 0 dB or can be set up to 15 dB in 1 dB
increments. In addition, uplink and downlink gains of each RAU can be independently attenuated
by 0 or 10 dB using AdminBrowser.
The recommended maximum lengths of CATV cable are as follows:
• For RG-59
cable 130 meters for CommScope PN 2065V
• For RG-6 c
able 140 meters for CommScope PN 2279V
• For RG-11
cable 235 meters for CommScope PN 2293K.
If the maximum distance is not required, then copper-clad over steel c
enter-conductor cable may
be use to reduce cable costs.
If the CATV cable is longer than the recommended distance per cab
le type, the gain of the system
will decrease, as shown in Table 69.

* Exceeding the distance of copper-clad
cable will result in
the connected RAU becoming
non-functional. If the distance of a cable run is at its maximum and is of concern, use solid copper
cable to ensure successful operation.
