Sorry that was just a reference to the fact that FDDI is deployed in the past. You'd have to figure that if the effort was made to use a dedicated fiber network in a complex, business or government, they'd still be using it wouldn't they?
FDDI was 100 Mbit, so at this point having ripped it out and replaced it with gigabit or faster ethernet is quite likely.
The reference also said it's losing ground, but as with all things tech, optical connections are becoming commonplace in IoT and old stuff becomes new again.
The paranoid me wonders if my computer speakers are a microphone also. :-0
They can be used that way in some cases. And many modern audio chips have pin routing configuration so you could remap the speaker jack as a microphone jack. Probably wouldn't work well, but I would not say it couldn't be done. -- Len Sorensen
