Does Xantech CPL94B remove the IR signal from the line?

I am using the Xantech Xtralink products to transmit IR back to my wiring closet and everything is working great. I now want to extract IR on one of the coax runs before the wiring closet, and again at the wiring closet. Does the CPL94B remove the IR from the line, or extract it to the IR outputs and leave it on the line? Or do I need to remove it and re-inject it at the same time in order for this to work?
