Working Principle

Figure 1 illustrates the working principle of the H83DFDSH board.

Figure 1 Working principle of the H83DFDSH board

The basic working principle of the H83DFDSH 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 protection module protects and isolates the board from lightning strikes.

  • 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 H83DFDSH board.
