FIDDI – (Fiber Distributed Data Interface) the standard was developed by American National Standards Institute (ANSI) XT39.5 in the mid-80’s. FIDDI utilizes 4 specifications requirements due to standardization allows the common bond for transmitting information (Cisco). Media Access Control (MAC) – specification defines how the medium is accessed, including frame format, token handling addressing, algorithms for calculating cyclic redundancy check (CRC) value, and error-recovery mechanisms. Physical Layer (PHY) – This specification defines data encoding/decoding procedures, clocking requirements, and framing, and other functions. Physical-Medium Dependent (PMD) – defines the characterisitics of the transmission medium, including fiber-optic links, power levels, bit-error rates, optical components, and connectors. Station Management (SMT) – defines FDDI station configuration, ring configuration, and ring control features, including station insertion and removal, initialization, fault isolation and recovery, scheduling, and statistics collection. Fiber-Optic Cable: is a popular high-bandwidth transmission medium.
