What type of test and trouble shooting equipment is available for FDDI?
FDDI protocol analyzers of varying capability are available from multiple manufacturers. Many FDDI equipment vendors also have management software that implements ring mapping, inspection of other stations operational parameters, general ring state monitoring, etc. An optical time domain reflectometer (OTDR) and optical power meters are used for testing optical fiber. There are also FDDI link testers that measure power and low level FDDI protocol response.
