Product Overview<\/h2>\n

Premlink is a WDM passive node factory in China that has been producing various types of passive nodes for many years. PL190A-5D WDM Passive node is power-free, meaning it doesn’t require any power supply. It can split mixed signals into XGSPON & GPON signals and CATV signals. PL190A-5D is very simple to install, requiring only that the RF output port be connected to a TV set or STB via cox cable. It has two optical connectors: one for mixed input fiber connector and another for inserting directly to XGSPON & GPON ONU. To be a WDM passive node factory, Premlink designed it into simple and cost-effective.<\/p>\n

PL190A-5D: XGSPON Compatible Passive Node from a Leading Factory<\/h2>\n

A high-performance, power-free WDM receiver designed by a professional WDM passive node factory for next-gen 10G-PON networks.<\/p>\n

    \n
  • XGSPON Future-Proofing:<\/strong> As a specialized wdm passive node factory<\/strong>, Premlink integrated an advanced FWDM filter to support simultaneous pass-through of both GPON (1310\/1490nm) and XGSPON (1270\/1577nm) data signals.<\/li>\n
  • Maintenance-Free Energy Harvesting:<\/strong> The PL190A-5D is a 100% power-free unit<\/strong>, converting 1550nm optical power into high-quality RF signals without the need for an external power supply or battery.<\/li>\n
  • Dual-Output Efficiency:<\/strong> Features a “D-style” dual RF output configuration, enabling the connection of two TV sets or Set-Top Boxes from a single fiber drop\u2014ideal for modern multi-room households.<\/li>\n
  • Zero-Configuration Installation:<\/strong> Simply connect the mixed fiber input and link the RF output via coaxial cable. It\u2019s the most cost-effective solution for rapid RF overlay deployments in XGSPON architectures.<\/li>\n
  • Industrial Endurance:<\/strong> Designed for extreme conditions, this wdm passive node<\/strong> operates flawlessly from -40 to +85\u2103<\/strong>, ensuring carrier-grade reliability in any indoor environment.<\/li>\n<\/ul>\n<\/div>\n

    Technical FAQ: WDM Passive Node Factory Insights<\/h2>\n
    \n

    Q1: What defines Premlink as a premier WDM passive node factory?<\/h3>\n

    A:<\/strong> Being a dedicated wdm passive node factory<\/strong>, Premlink focuses on high-sensitivity PIN diode integration and precision FWDM filtering. Our factory-direct approach ensures that every PL190A-5D meets strict optical return loss (\u226545dB) and insertion loss (\u22641dB) standards, providing a professional alternative to low-quality trading company products.<\/p>\n<\/div>\n

    \n

    Q2: How does this passive node handle 10G-PON (XGSPON) interference?<\/h3>\n

    A:<\/strong> The PL190A-5D features an upgraded optical filter specifically designed to isolate the 1577nm downstream and 1270nm upstream XGSPON signals. This prevents data packets from leaking into the RF path, ensuring zero interference with your CATV\/4K broadcasting services.<\/p>\n<\/div>\n

    \n

    Q3: Can I customize the labeling as part of the factory service?<\/h3>\n

    A:<\/strong> Yes. As a wdm passive node factory<\/strong>, we offer flexible OEM\/ODM services, including customized temporary labels and logos even for small MOQ requirements, helping you build your local brand identity in the FTTH market.<\/p>\n<\/div>\n<\/div>\n
