Fiber optic cables: How they work

[Onserio.]

I had asked this question in my I.T class about 12 years ago. Finally got the answer at 2:14am. It is amazing.

Bill, I am a network engineer and studied and employed Asynchronous Transfer Mode for a city in Oregon. My most common challenge was refraction changes due to over-eager "diggers" and cable-installers on the poles. Sometimes, the glass fiber cable would develop and "fracture" or break. This was like a monkey wrench in the works and so I truly appreciate your discussion of refraction. I love the engineer's perspective and your clear and concise teaching method!!!

Why are people disliking a purely informative video

[TheMxboy]

I could listen to this guy talk about anything

[kernalkorn]

I love the animation where the binary approximations on the graph merge into a single line of binary code. It's a nice touch and it helped me see what's going on. Thank you Sir!

Have to appreciate countless past engineers and scientists who have shaped our world and open the doors for further discovery and engineering. Channels like this are an inspiration and deserve at least as many views at youtube's reaction or prank channels.

I love the background music. It sounds like the tutorial level of a RPG.

Wish I had watched these videos before all of my digital communications classes. The big picture overview explained in layman's terms are very helpful. Often professors speak as if they are talking to a room of experienced professionals making it very hard to follow. Thank you for the videos!

My college teachers couldn't made me understand optical fiber in a full semester.
you did it in just 5 mins..




hats off sir

[JUMOWAx]

you mentioned 50k phone calls can be sent simultaneously. How come the signals don't irritate each other while being sent through the cable?

[Tortee]

this guy explains perfectly, not stupid like explaining to a 4 year old, and not overly complicated like explaining to a college student

Wow, I always imagined the transatlantic cable as being so much larger! I figured it was over a foot in diameter, and marveled at the sheer amount of material it would have taken, but that it's able to be so small yet durable and able to transmit to much information is even more marvelous!

The sample with the bucket is awesome. Love your videos. Thanks!

[demonman]

His presentation is phenomenal. Educational, yet, despite not making a single joke or witty line, he makes it entertaining with his voice alone.

[VoidFame]

I'm so happy to see information presented in this style. No distracting questions. No personal confusions. Just principle and design explained clearly and efficiently.

[shivamanand]

I've studied all this in just theory. It's really amazing to see these theoretical concepts applied in real world. I just wish I had a professor like him.

[cosmicpuma]

Wow.... Incredible... The most incredible part is how you took such complex information and explained it in such a wonderful way. Thank you.

Why is this on my recommendations?

nvm, I learned something new

[scottwarneronline]

How do they boost the signal within the cable?
