Japanese analysts say the latest network speed test results will enable the latest connectivity and thus help “bandwidth-hungry businesses.”
Japanese researchers demonstrated network speeds of 319 megabits per second and produced a global report. Using superior fiber optic technology, researchers at Japan’s National Institute of Information and Communication Technology (NICT) tested speeds using a conventional four-core fiber with an outer diameter of 0.125 mm, beating the previous report of 178 megabits per second established by Japanese and British engineers last year.
To achieve this speed, the researchers combined two amplifiers on the rare-earth-doped fiber to form an experimental setup with a circular transmission loop. By combining erbium and tulium fiber amplifiers with distributed Raman amplification, they were able to transmit signals over long distances – more than 3,001 km.
According to a paper published earlier this month by the Japanese think tank, “Four-core MCF fibers with conventional cladding diameters are suitable for common cabling infrastructures and are expected to offer mechanical reliability equivalent to single-mode fibers, making them attractive for early deployment of SDM fibers in high-performance hyperlinks over long distances. This makes it attractive for early deployment of SDM fiber in long-haul, high-performance hyperlinks.”
NICT believes it is important to show how the new fiber will be able to handle the “explosive growth in demand” expected from new data businesses. The results of recent network speed tests also show that the latest communications technology can help support new “bandwidth-hungry enterprises” and that there is room to find ways to further improve the capacity of “low-speed multicore and other new SDM fibers.” said NICT.
NICT “will also continue to work on expanding inter-ocean data transmission,” it added.
The results of the analysis were presented at the Global Fiber Communications Conference, held June 6-11.
The results are comparable to the 512 kbps offered by a typical Indian broadband company, while NASA’s backbone operates at 400 gigabits per second.
The achievement by the researchers at Japan’s National Institute of Information and Communication Technology (NIICT) is all the more interesting because they used a modern fiber optic infrastructure to achieve the advertised speeds. This means that their approach can be integrated with fiber infrastructure with minimal effort.
Satellite broadband. A faster way to connect India
NIICT has completed 3,001 km of long-distance transmissions, and this demonstration shows that modern cable technology is possible in the near term.
Members of the Indian Broadband Group welcomed this new development.
TV Ramachandran, chairman of the Indian Broadband Review Committee, said existing transmission methods were generally unable to meet the huge demand for information in India – the best food on the planet. He estimated that “less than 500 million consumers currently have access to the internet, and that number will grow.”
By the fourth quarter of 2020, Jio will have the fastest fixed broadband speeds and Vi India will have the fastest mobile speeds. OOKLA
In addition, video content is particularly popular among Indians, which requires faster speeds,” he adds. This is a challenge because existing data transmission methods, which centralize information in a central processor, are often unable to cope with such high volumes. So this change in development is necessary,” says Ramachandran.
Pranav Roach, president of satellite broadband company Hughes Community Technologies India Ltd, believes it will be some time before the technology is deployed in the field. This venture will require a significant and long-term investment, after which it will take a long time to translate into a real solution, although it is a step in the right direction for the better.”
