    Technical FAQ: PL2000H Erbium Doped Fiber Amplifier<\/h2>\n
    \n

    Q1: What are the adjustment steps for the PL2000H output power?<\/h3>\n

    A:<\/strong> The PL2000H allows for extremely precise tuning. You can adjust the output power from -10 to +0.5dBm<\/strong> in 0.1dB increments<\/strong>. This can be done via the front panel touchscreen or remotely through the Web GUI.<\/p>\n<\/div>\n

    \n

    Q2: Does Premlink offer OEM services for the management interface?<\/h3>\n

    A:<\/strong> Yes. As a dedicated manufacturer, we provide customized logos, labels, and Web copyrights<\/strong>. This means you can have your own brand information displayed on the physical unit and within the software interface, even for an MOQ of 1 piece<\/strong>.<\/p>\n<\/div>\n

    \n

    Q3: How many ports are available in the standard 1U model?<\/h3>\n

    A:<\/strong> The standard 1U PL2000H model is optimized for high-density headends, offering 1, 2, 4, or 8 output ports<\/strong>. For higher port counts (up to 256), we recommend our 2U and 3U high-power series.<\/p>\n<\/div>\n

    \n

    Q4: What happens if one of the power supplies fails?<\/h3>\n

    A:<\/strong> The PL2000H features dual hot-pluggable power supplies<\/strong>. If one module fails, the system automatically switches to the backup source without any service interruption, and an alarm is triggered via SNMP to notify the administrator.<\/p>\n<\/div>\n<\/div>\n
