Los investigadores de la Universidad de Aston han enviado datos a una velocidad 4,5 millones de veces m\u00e1s r\u00e1pida que la banda ancha dom\u00e9stica promedio. La velocidad es la m\u00e1s r\u00e1pida jam\u00e1s enviada al abrir nuevas bandas de longitud de onda espec\u00edficas que a\u00fan no se utilizan en los sistemas de fibra \u00f3ptica. Se logr\u00f3 abriendo nuevas bandas de longitudes de onda que a\u00fan no se utilizan en los sistemas de fibra \u00f3ptica. Diferentes bandas de longitud de onda equivalen a diferentes colores de luz que se transmiten a trav\u00e9s de la fibra \u00f3ptica.<\/p>\n
Aston University researchers have sent data at a speed that is 4.5 million times faster than the average home broadband. As the demand for more data increases, it is expected the newly developed technology will help keep up with future demand. The scientists used optical fibres, small tubular strands of glass that pass information using light. Regular copper cables can\u2019t carry data at such speeds. \u201cOver the last few years Aston University has been developing optical amplifiers that operate in the E-band, which sits adjacent to the C-band in the electromagnetic spectrum but is about three times wider. Before the development of our device, no one had been able to properly emulate the E-band channels in a controlled way.\u201d<\/p>\n Professor Forysiak added: \u201cBy increasing transmission capacity in the backbone network, our experiment could lead to vastly improved connections for end users.<\/p>\n \u201cThis groundbreaking accomplishment highlights the crucial role of advancing optical fibre technology in revolutionising communication networks for faster and more reliable data transmission.<\/p>\n \u201cGrowing system capacity by using more of the available spectrum – not just the conventional C-band but also other bands such as the L, S and now E-bands can help to keep the cost of providing this bandwidth down.<\/p>\n \u201cIt is also a \u2018greener solution\u2019 than deploying more, newer fibres and cables since it makes greater use of the existing deployed fibre network, increasing its capacity to carry data and prolonging its useful life & commercial value. \u201c<\/p>\n The results of the experiment were published this month by the Institute of Engineering and Technology, the IET, and were presented as a post-deadline paper at the European Conference on Optical Communication (ECOC) held in Glasgow, October 2023.<\/p>\n
The rate is the fastest ever sent by opening up specific new wavelength bands that are not yet used in fibre optic systems.
As part of an international collaboration, the academics transferred data at a rate of 301 terabits or 301,000,000 megabits per second, using a single, standard optical fibre.
That\u2019s compared to Ofcom\u2019s UK home broadband performance report published in September 2023 which stated that the average broadband speed is just 69.4 Mbit\/s megabits per second. \u00a0
Professor Wladek Forysiak\u00a0<\/a>from\u00a0Aston Institute of Photonic Technologies<\/a>\u00a0and\u00a0Dr Ian Phillips<\/a>\u00a0were part of the team that successfully transmitted the data. They worked in collaboration with researchers from National Institute of Information and Communications Technology (NICT) in Japan and Nokia Bell Labs in the USA.<\/p>\n
The feat was achieved by opening up new wavelength bands that are not yet used in fibre optic systems. Different wavelength bands are equivalent to different colours of light being transmitted down the optical fibre.
They did this by developing new devices called optical amplifiers and optical gain equalizers to access them.\u00a0
Dr Phillips led the development of a management device, or optical processor, at Aston University. He said \u201cBroadly speaking, data was sent via an optical fibre like a home or office internet connection.\u00a0
\u201cHowever, alongside the commercially available C and L-bands, we used two additional spectral bands called E-band and S-band. Such bands traditionally haven\u2019t been required because the C- and L-bands could deliver the required capacity to meet consumer needs.<\/p>\n
