Product Overview<\/h2>\n

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.<\/p>\n

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 60C\u00ba).<\/p>\n

PL3100A Broadband Amplifier can be field upgradable to an Optical Node.<\/p>\n

    Technical FAQ: PL3100A Broadband Amplifier<\/h2>\n
    \n

    Q1: How does the PL3100A handle extreme outdoor environments?<\/h3>\n

    A:<\/strong> The PL3100A broadband amplifier<\/strong> is housed in an IP68-rated<\/strong> strand-mount enclosure. It includes built-in thermal compensation circuitry and \u00b16kV surge protection (IEEE C62.41), ensuring stable gain and hardware integrity from -40\u00b0C to +60\u00b0C.<\/p>\n<\/div>\n

    \n

    Q2: Can the frequency split be customized for different regional standards?<\/h3>\n

    A:<\/strong> Yes. While the standard forward path is 54-1002MHz and return path is 5-42MHz, the PL3100A<\/strong> can be built with different frequency splits to comply with various international CATV standards, ensuring seamless integration into any global HFC networks.<\/p>\n<\/div>\n

    \n

    Q3: What is the benefit of the MGC (Manual Gain Control) mode?<\/h3>\n

    A:<\/strong> MGC mode allows for precise manual balancing of the broadband amplifier<\/strong> during installation. By using plug-in attenuators, technicians can lock in the exact gain and slope required to compensate for cable loss, preventing over-driving of downstream equipment.<\/p>\n<\/div>\n<\/div>\n
