Fiber cut

> “This is a clear example of the FAA’s outdated infrastructure and underscores the urgent need to modernize our air traffic control systems,” the agency said in its Sept. 20 update. “Moving from aging, analog systems to more resilient, digital technology, is critical to maintaining the reliability and resiliency of the national airspace system.”

Umm, what? How is a fiber cut an "aging, analog system"? They even admitted that there was supposed to be redundancy in place but the system did not work.

It's not the fiber that's the problem. I mean, it is ... but that's not the analog part we are talking about.

ATC communications are still over two-way radio. It's like walkie-talkies but on aviation bands instead of citizen bands. There are digital communications in some cases but it's definitely not the baseline.

And that part is not the problem.

It’s a good example of legacy technology with severe flaws

		And with nothing approximating good (let alone better) to replace it.

Fiber can be and often is used to carry wideband analog signals.

Oh you know, analog telephone wires, digital fibre, they're both wire shaped so they're the same.
