Serial Front Panel Data Port(Serial FPDP or SFPDP) is a high speed low latency data streaming serial communication protocol. It currently supports several distinct speeds:

• 1.0625 Gbit/s
• 2.125 Gbit/s
• 2.5 Gbit/s
• 5.0 Gbit/s
• 6.25 Gbit/s
• 8.5 Gbit/s
• 10 Gbit/s
• 10.3125 Gbit/s
• 25.78125 Gbit/s

Serial FPDP also recommends the use of one of the following link widths:

• x1
• x4
• x8
• x12 (5 Gbit/s and up)
• x24 (5 Gbit/s and up)
• x48 (10 Gbit/s and up)

Serial FPDP can operate over long distances, up to 10 kilometres (6.2 mi), using optical fiber cables, or shorter distances over copper cables.
