    CDDI – Copper Data Distribution Interface

    Abbreviation of 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 Twisted Pair Physical Layer Medium (TP-PMD). TP-PMD is the general ANSI standard name for this FDDI -like service.

    CDDI cable lengths are limited to 100 meters.
