I don't live in Canada at the moment. But I used to live in Toronto.
Ah. I've watched several of your videos, and I thought you were still teaching at the U of T. I'm from Toronto, and a U of T grad from 1987, but now I've moved to Vancouver after spending most of my career in the USA at various companies and in multiple states.
I've never worked with fiber optics so your video was fascinating to watch. I'm curious, though, does the fiber have a specified lifetime and eventually wear out or even break with all that twisting?
Thanks and keep up the great videos, there's always something to learn.
PS: as a seasoned engineer I like when they get technical and very detailed (high-level as you say) and those are the videos that are most interesting to me. So my feedback is to keep up the mix of low and high-level videos and you'll keep a good mix in your audience.
Cheers!
