About This Part
The Part Number GFGM, known as the ZTE GFGM, is a critical component within ZTE's Gigabit Passive Optical Network (GPON) Optical Line Terminal (OLT) systems. This advanced line card is designed to be inserted into a compatible OLT chassis, serving as the primary interface for delivering high-speed broadband services to end-users. Functionally, the GFGM board provides multiple GPON optical ports, each adhering to the ITU-T G.984 standard, enabling robust downstream data rates of 2.488 Gbps and upstream rates of 1.244 Gbps. Each port typically supports a split ratio allowing connectivity for up to 128 Optical Network Units (ONUs) or Optical Network Terminals (ONTs) over a single fiber, utilizing distinct wavelengths for transmission (1490 nm downstream, 1310 nm upstream). This board ensures efficient and scalable fiber-to-the-home/business (FTTH/FTTB) deployments, facilitating the aggregation and distribution of data traffic within the access network. The ZTE GFGM board is deployed extensively in the access layer of modern telecommunication networks, specifically within ZTE's Optical Line Terminal (OLT) chassis such as the C300 or C320 series. Its primary application is to provide the optical aggregation point for Fiber-to-the-Home (FTTH), Fiber-to-the-Business (FTTB), and Fiber-to-the-Curb (FTTC) deployments. Telecommunication operators, Internet Service Providers (ISPs), and even large campus networks utilize this board to deliver high-speed internet, IPTV, and VoIP services over a single optical fiber infrastructure. The GFGM addresses the growing demand for bandwidth, enabling operators to replace legacy copper-based access technologies like DSL with a more scalable, reliable, and future-proof fiber solution. It facilitates the expansion of existing GPON networks, allowing service providers to connect new subscribers or upgrade service tiers for current customers efficiently, thereby solving the critical "last mile" connectivity challenge with high performance and reduced operational complexity. For B2B clients seeking cost-effective and reliable infrastructure solutions, Revo Distribution Limited offers used and refurbished units of the ZTE GFGM board.
