Tools and guidelines for optimizing system performance will increase productivity and improve efficiency, helping the reader make more intelligent, cost-efficient decisions for their networks.
Copper Distributed Data Interface
Copper Distributed Data Interface (CDDI) is the implementation of FDDI protocols over twisted-pair copper wire. Like FDDI, CDDI provides data rates of 100 Mbps and uses dual-ring
architecture to provide redundancy. CDDI supports distances of about 100 meters from desktop to concentrator.
CDDI is defined by the ANSI X3T9.5 Committee. The CDDI standard is officially named the Twisted-Pair Physical Medium-Dependent (TP-PMD) standard. It is also referred to as the Twisted-Pair Distributed Data Interface (TP-DDI), consistent with the term Fiber Distributed Data Interface (FDDI). CDDI is consistent with the physical and media-access control layers defined by the ANSI standard.
The ANSI standard recognizes only two types of cables for CDDI: shielded twisted pair (STP) and unshielded twisted pair (UTP). STP cabling has 150-ohm impedance and adheres to EIA/TIA 568 (IBM Type 1) specifications. UTP is data-grade cabling (Category 5) consisting of four unshielded pairs using tight-pair twists and specially developed insulating polymers in plastic jackets
adhering to EIA/TIA 568B specifications.
Figure 9-11 illustrates the CDDI TP-PMD specification in relation to the remaining FDDI specifications.

Summary
The Fiber Distributed Data Interface (FDDI) specifies a 100-Mbps token-passing, dual-ring LAN architecture using fiber-optic cable. FDDI is frequently implemented as a high-speed backbone technology because of its support for high bandwidth and greater distances than copper.
