Copper Data Distribution Interface, a
network technology capable of carrying data at 100
Mbps over
unshielded twisted pair (UTP) cable. CDDI is a trade name of Crescendo Communications (acquired by Cisco Systems in 1993) and commonly used instead of the general term

ANSI standard name for this
FDDI -like service.
CDDI cable lengths are limited to 100 meters.
