The basic working principle of the H801XGBD board is as follows:
l The control module loads the board software, controls the running of the board, and
manages the board.
l The switching module aggregates the signals from eight 10G GPON ports.
l The interface module converts between 10G GPON signals and Ethernet packets.
l The power module supplies power to other functional modules of the board.
l The clock module provides the working clock for other functional modules of the board.
