Investigated create 40 Gbps connections to the home without increasing costs
Although currently there are ways to achieve multi-gigabit connections per second over fiber optic networks to install this entails high costs. Right now there are some services that only offer 1 Gbps to the home, such as Google in Kansas, or part of Virgin Media in London.
This could change if the research is being done at the University of Bangor in Wales, UK, is successful. According to them, the project could achieve that reached speeds up to 40 Gbps, without having to invest large sums of money.
Today, Optical fiber networks to send data taken from our computers (zeros and ones) and become light to transport. However, as the cable length increases, it becomes more difficult to send the light, a problem known as “dispersion”. To resolve this, is usually to increase the number of fibers in the cable, the number of lasers that send information and technology to amplify the signal, to allow the full message and error comes up the other side.
However, all these options are expensive. The researchers took advantage of a technique used in transmitting information wirelessly to solve this problem otherwise known as Optical Orthogonal Frequency Division Multiplexing (OOFDM).
The idea is to take the data, convert them into electric waves, into optical signals and then transmit them. To make all these changes (which must then be converted to the original so we can see), the research team is developing special modules using inexpensive materials. The idea is that the module is commercially viable, and exploiting the structure of existing optical fiber without having to install anything new.
So far, they have managed to make it work transmitting speeds up to 20 Gbps.Broadband, Gbps, Optical fiber, Speed, United Kingdom
