Product Overview<\/h2>\n

The PL3000A optical segmentable\u00a0 node is designed for fiber-deep HFC networks. It has two high-level RF output ports. Each high level RF output port can be divided into two low-level output ports.\u00a0 All attenuation and equalization modifications will be made with ordinary JXP type pads.<\/p>\n

PL3000A optical segmentable node’s reverse traffic can be mixed and routed using a DFB return transmitter module. Bi-directional TPs allow the operator to monitor and inject through a single TP connection. PL3000A optical segmentable node’s will be able to upgrade from a PL3100A amplifier to an optical node. This type of segmentable node will be field upgradeable from a forward-only to a forward-return path product.
\nPL3000A optical segmentable node’s is adaptable to unique network requirements due to the use of selectable optical connectors, strand mounting, and international frequency split.<\/p>\n

    Technical FAQ: PL3000A Segmentable Node<\/h2>\n
    \n

    Q1: What are the benefits of using a segmentable node in HFC networks?<\/h3>\n

    A:<\/strong> A segmentable node<\/strong> like the PL3000A allows you to split a single optical node into multiple independent RF segments. This effectively reduces the “service group” size, increasing the available per-user bandwidth for high-speed data and VOD services without extensive re-cabling.<\/p>\n<\/div>\n

    \n

    Q2: Does the PL3000A support bi-directional traffic monitoring?<\/h3>\n

    A:<\/strong> Yes. It features bi-directional Test Points (TPs)<\/strong>, enabling operators to monitor and inject signals through a single connection point. This drastically simplifies field maintenance and network balancing for return path traffic<\/strong>.<\/p>\n<\/div>\n

    \n

    Q3: How is the output level managed across different temperatures?<\/h3>\n

    A:<\/strong> The PL3000A is equipped with Thermal Compensation<\/strong> on-board and supports both MGC and AGC modes<\/strong>. This ensures the 110dB\u00b5V output level remains stable within \u00b11.5dB even during extreme outdoor temperature fluctuations from -40\u2103 to +60\u2103.<\/p>\n<\/div>\n

    \n

    Q4: Can this node be upgraded from an existing amplifier?<\/h3>\n

    A:<\/strong> Absolutely. Our modular architecture allows for a seamless field upgrade<\/strong> from a PL3100A amplifier to a full-featured optical node by adding receiver and transmitter modules, protecting your initial infrastructure investment.<\/p>\n<\/div>\n<\/div>\n
