Hollow Core Fiber explained (01-10-01)

Everyone seems to be talking about hollow core fiber. But what is it and what makes it so different to single mode fiber?!? In this #brainsnack video James F. Merchant breaks it down and explains why it is generating so much attention right now. One of the takeaways that might surprise you is that in a #HCF light travels significantly faster than in #SMF making it ideal for #AI data centers. Where do you see that HCF will have the biggest impact in the next few years? There is so much more to hollow core fibers, so if you have any questions, drop them in the comments. 0:00 - Intro 0:21 - How hollow core fiber works (vs. single mode fiber) 1:07 - Latency advantage – How much faster is it really? 2:22 - Attenuation explained – Why losses are lower 4:06 - Challenges and current limitations Corrections: 0:30 The cladding has a lower refractive index 3:07 The correct term is leakage loss
