About product
The Huawei GPFD and GPBD are high-performance GPON (Gigabit Passive Optical Network) service boards designed for Huawei OLT (Optical Line Terminal) systems. These boards provide multiple GPON ports for high-speed, stable, and scalable fiber-optic broadband access, making them ideal for FTTH (Fiber-to-the-Home) and FTTB (Fiber-to-the-Building) deployments.
Product feature and application of the GPBD:
- The control module completes the function of loading, running control and management of the board.
- The switch module implements aggregation of eight GPON port signals.
- The interface module implements the conversion between GPON optical signals and Ethernet packets.
- The power module provides the working power for each function module in the board.
