When Covid-19 hit the internet, everyone plugged in. Kids went to school on Zoom; adults followed suit at work. Desperate to escape from the virus that ravaged their lives, people binged Netflix and doomscrolled until they couldn’t take it anymore!
The internet is a vast, ever-expanding ocean of information. And the world needs more and more bandwidth to keep up with this fast-paced life we live in now– from streaming movies on Netflix to playing games online against friends halfway around the globe. Yet despite all these changes, there were no headlines of mass outages or server farms catching fire as demand for internet speeds went through the roof at 60 percent last May, according to an OECD report released in July 2018.
It can be hard to predict the future but assuming that our current trajectory is a pretty safe bet. The internet has had an unprecedented impact on how we communicate and share information with one another; in turn, it’s changed culture and society as well. Who knows what will happen?
Last year, the University College London team set a record for internet speed at 178 terabits per second. Now, Japan’s NICT (National Institute of Information and Communications Technology) researchers have nearly doubled that mark with speeds of 319 terabits per second.
NICT has been able to build a long-distance transmission system around the 4 core optical fiber with standard cladding diameter, which allows for more bandwidth and information that does not deteriorate or slow over lab constructed distances as far as 3,001km.
The full form of TP/s stands for Terabytes Per Second where 1 TB=1000 GB meaning . One Gigabyte is equivalent to 1024 Megabytes. You could download more than 7,000 movies in a second if you were downloading at that speed of 319 terabits per second.
Keypoints with the latest advancements at NICT
- 319 Tb/s long-haul transmission of wideband (>120 nm) S, C and L-bands signal using 552 PDM-16QAM, wavelength-division multiplexed channels in a 4-core optical fiber
- Long-distance transmission over 3,001 km enabled by adoption of both erbium and thulium doped-fiber amplifiers and distributed Raman amplification
- Demonstration shows potential of SDM fibers with standard-cladding diameter and compatibility with existing cabling technologies for near-term adoption of high-throughput SDM fiber systems.
