It basically takes part of the line card customers connect to and puts it out in the field. The fibre link between node and hubsite goes from analogue to all digital.
The remote PHY receives 1s and 0s from the hub site, across the fibre link, which it turns into RF for the cable modems and sends down the coax, and it converts RF arriving on the coax
from the modems into 1s and 0s to go into the upstream laser.
