PL3100A Broadband Amplifier is a 1GHz bandwidth two-way amplifier. It is designed specifically for use in fiber deeper cable TV networks. PL3100A Broadband Amplifier has two high level RF outputs in only main portsoutput mode, that can be split into four low level outputs in main and aux ports output mode. PL3100A Broadband Amplifier has GaAs technology in use, that guarantees the highest CTB and CSO performance.
PL3100A Broadband Amplifier’s adjustments of output level and slope are made using standard JXP PADs to minimize spare parts. AC shunt power directors located near the ports. These power directors are used to direct AC current to/from the amplifier input and output ports. AC circuitry provides 10A of steady state current capability that is able to with stand 15A of peak current (maximum 2 hours at 60Cº).
PL3100A Broadband Amplifier can be field upgradable to an Optical Node.
