GBE FAT PIPE SWITCH MODULE
Fig. 5-1 shows how the GbE fat pipe switch module maps to ports defined by the AMC.0
specification; see
Fig. 1-3 for the full port mapping diagram.

Fat Pipes: This region supports data path connections such as GbE. It can carry large amounts of data
without significantly degrading the speed of transmission.
x1: This refers to the link width of the port (the number of lanes that can be used to intercon-
nect between two link partners).
The following diagram shows the implementation of the GbE fat pipe switch module on the
KAT4000:
