True. The industry is on decline. On the way to other utilities.

But then any project is a challenge. Not just fiber that may be cheaper for Metro than DWDM.

Well, ISP is typically plan something for a year. It is more than enough for both.

Funny, that with the current lead times for electronics, Fiber could be faster.
Of course, it is a temporary glitch.
