System Gain
6.4 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 inde-
pendently 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 cable 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 center-conductor
cable may be use to reduce cable costs.
If the CATV cable is longer than the recommended distance per cable type, the gain
of the system will decrease, as shown in Table 6-13.
