Figure 1 Working principle of the H82DFDSD board

The basic working principle of the H82DFDSD board is as follows:

• The switch module switches the backplane port to the chipset module port.

• The chipset module implements functions such as amplification, filtering, analog-to-digital (A/D) and digital-to-analog (D/A) conversion, coding/decoding, and encapsulation/decapsulation for the signals.

• The control module decodes and monitors signals.

• The power module supplies power to other function modules of the board.

• The clock module provides the working clock signals for other function modules of the board.

The Centralized vectoring processing board processes vectoring signals and provides a 10G-KR port to connect to the H82DFDSD board.
