H836VPJB

H836VPJB is a centralized vectoring processing board. It supports system level vectoring of VDSL2, SuperVector, and G.fast services and is used for calculating and canceling the line crosstalk of the system.

Functions and Specifications

• The board supports system-level vectoring of VDSL2, SuperVector, and G.fast services.

• The board processes vectoring signals and provides a 10GKR port to connect to a service board.

Figure 1 Working principle of the H836VPJB board

The basic working principle of the H836VPJB board is as follows:

• The vectoring processing module performs vectoring processing and computing for VDSL2, SuperVector, and G.fast services.

• The level conversion module implements conversion between single-end level and differentiated level for the clock and time interface of the board.

• The protection module protects and isolates the board from lightning strikes.

• 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.
