Though only a very small group of fiber technicians gets to work with undersea fiber optic systems, this is without a doubt among the most fascinating subjects in the telecommunications world sparking #curiosity in tech and non-technical folks alike!
From experience working in cable landings years ago, it always amazed me how the infrastructure for carrier hotels and sub-sea transmission systems was designed to work at much grater scale than common terrestrial systems, similarly to modern hyper-scale data centers. This to support the large amount of carriers and long distance service providers collocating to access transport facilities.
I remember in the early 2000s, (some might remember the days of Lucent, Global Crossings, Level 3, etc., when putting that names Lucent and Alcatel next to each other would have been considered an oxymoron), testing Corning's LEAF Non-Zero Dispersion-Shifted (NZ-DSF) Single Mode Fiber (G.655) and Lucent's TruWave RS (reduced slope/dispersion) for Project Oxygen, which at the time had fiber transport links transmitting above 1.92 Tbps (TB for Terabits) and connecting most continents in the world. More recent systems by Infinera are reported to work at 26.2 terabits per second (Popular Science Mag). Crazy stuff! 🤯
Anyway, we are always curating resources to share with friends, followers, and FiberWizards, and came across this video which I think is among the better ones I've seen so thought I'd share.
Below is the link, and hope you enjoy! 🚀
