[PDF] Fibre Distributed Data Interface (FDDI) – Token Ring Twisted Pair Physical Later Medium Dependent (TP-PMD)

The described Twisted Pair Physical Layer Medium Dependent Standard is intended for use in a high-performance multistation network. This protocol is designed to be effective at 100 megabits per second using a token ring architecture and twisted pair cabling as the transmission medium over link distances of up to one hundred meters.
