As the name implies, it is directly related to Standard Front Panel Data Port (FPDP), deriving its serial protocol from the defined protocol and control signals of FPDP. Serial FPDP currently supports two link speeds, 1.0625 Gbaud and 2.5 Gbaud. These two link speeds can support data transfer rates in excess of 105 MBps and 245 MBps respectively.

It currently is defined to operate at two distinct link speeds, 1.0625 Gbaud and 2.5 Gbaud – with sustained data rates in excess of 105 and 245 Mbytes/sec. respectively. Serial FPDP can also operate over long distances (up to 10 kilometers) using fiber optic cable. 1.1 Standard
