Characteristics of FDDI technology

1-6
The MPMC221/MPMC222 exceed the maximum power
dissipation as stated in the CMC Standard (IEEE P1386
Draft 2.0). The system designer should follow the
recommendation as stated in the PMC Standard (IEEE
P1386.1 Draft 2.0).
The MPMC221/MPMC222 requires the following operating
environment:
Operating temperature
Storage temperature
Operating humidity, non-condensing
Storage humidity, non-condensing
Forced air cooling is not required when the ambient temperature is
below 40 degrees C. Above 40 degrees C, forced air cooling is
required.
FDDI technology connects data processing equipment in very high
speed digital networks, using fiber-optic distributed cable.
An FDDI LAN can have up to 1000 physical connections, with a
maximum connection separation of 2 kilometers, and a total fiber
path length of approximately 200 kilometers. Benefits of fiber-optic
FDDI LANs over current IEEE 802 Ethernet LANs include lighter,
smaller, and more reliable media. Network data integrity is
enhanced by a 32-bit cyclic redundancy check (CRC) as specified by
FDDI standards.
