About This Part
The Part Number GFBL, known as the ZTE GFBL, is a high-density service board engineered for integration into ZTE's Optical Line Terminal (OLT) platforms. This advanced line card supports both Gigabit Passive Optical Network (GPON) and 10-Gigabit-capable Symmetric Passive Optical Network (XG-PON) technologies, providing 16 optical ports. Each port is capable of delivering robust broadband services, with GPON offering downstream speeds of 2.488 Gbps and upstream speeds of 1.244 Gbps, while XG-PON significantly boosts capacity with downstream rates up to 9.953 Gbps and upstream rates of 2.488 Gbps. The D2 designation typically refers to specific optical module specifications, ensuring compatibility and optimal performance within the OLT system. This board is critical for aggregating subscriber traffic and connecting to Optical Network Units (ONUs) or Optical Network Terminals (ONTs) in the last mile. This ZTE GFBL line card is primarily deployed within carrier-grade OLT chassis, such as the ZTE C300 or C320 series, forming the cornerstone of Fiber-to-the-Home (FTTH), Fiber-to-the-Building (FTTB), and Fiber-to-the-Curb (FTTC) deployments. Telecommunication operators, internet service providers (ISPs), and large enterprises leverage this equipment to deliver high-speed data, voice, and video services to their end-users. It addresses the growing demand for bandwidth by enabling the expansion or upgrade of existing GPON networks to XG-PON, offering a scalable solution for increasing subscriber density and service quality. The GFBL board is instrumental in solving last-mile connectivity challenges, providing a reliable and efficient platform for next-generation access networks.
