Hello friends , i am new at steemit and Project Hope Community ,from my side greetings to the nice and co-operative people of the @Project.Hope Community,
Also greetings to the community founder @crypto.piotr who has been making a lot of efforts to educate new comers and learners for so long

My first publication is about a news about Internet, i found trhough searching which i am sharing with source ,

LONDON: Experts at University College London have set a new Internet speed record by transferring data at a speed of 178 terabits per second of optical fiber. Simply put, at this speed, 1500 videos with 15 gigabytes can be downloaded in just one second.

The previous record for data transfer from optical fiber was 150.3 terabits per second, which was set in 2018 in Japan. The current record is about 18.5% faster than that.

Although this success has been achieved on an experimental and limited scale, experts say that with minor and low-cost changes to the existing optical fiber infrastructure, the technology will be able to make the Internet extraordinarily fast with great ease.
It should be noted that at present, the average speed of broadband internet worldwide in terms of downloads is 81.46 megabits per second, while the average speed of 4G mobile internet is 34.51 megabits per second. With a total download speed of 110.9 megabits per second, the UAE ranks first in the world.

Pakistan ranks 112th in the mobile internet with an average download speed of 17 megabits per second and an upload speed of 11.40 megabits per second, while broadband internet has an average download speed of 9.40 megabits per second and an upload speed of 7.85 megabits per second. With 159th number.

The maximum data throughput in a single mode optical fibre is a function of both the signal bandwidth and the wavelength-dependent signal-to-noise ratio (SNR). In this paper, we investigate the use of hybrid discrete Raman & rare-earth doped fibre amplifiers to enable wide-band signal gain, without spectral gaps between amplification bands. We describe the widest continuous coherent transmission bandwidth experimentally demonstrated to date of 16.83 THz, achieved by simultaneously using the S-, C- and L-bands. The variation of fibre parameters over this bandwidth, together with the hybrid amplification method result in a significant SNR wavelength-dependence. To cope with this, the signal was optimised for each SNR, wavelength and transmission band. By using a system-tailored set of geometrically shaped constellations, we demonstrate the transmission of 660 ×25 GBd channels over 40 km, resulting in a record single mode fibre net throughput of 178.08 Tbit/s.

How did this new breakthrough of the fastest internet at University College London come about? All the details are published online in the latest issue of “I Triple e Photonics Technology Letters”.

I Wish to Learn and Grow With this Beautiful Community :)

Take care and keep smiling :)
