Global Shortage of Electronic Components and how it affects Telecommunications

Hello Experts,
Maybe you don’t quite understand all this fuss about the scarcity of electronic components.
So I’m going to bring an image here in this post for you to think a little bit.
Note the column about what was the typical lead time before the crisis and what lead time we currently have.
Understand the size of the problem?

And what’s causing the shortage?

There is global chip shortage and seems like this is not going to see an end anytime soon. The manufacturing units are not getting enough semiconductor supply. The situation is such that the major technology and automotive industry giants are facing losses in sales as the production has been hampered.
