Broadband to Wideband: What it Means?

Move over, decade-old broadband, here comes wideband, if the revolutionary speed of sending data via fiber optic cables at 12,000 kilometers speed becomes a reality soon, which is sure to be in a couple of years from now.

University of California, San Diego engineers have increased the maximum power of signal to be sent through optical fibers, which provide the data transmission for the internet, cable, wireless and landline networks, at 12000 km speed without using additional power surge that may have distorted the information.

In a unique application, they used what a concert master does before starting his event by tuning multiple instruments to the same pitch. Similar to it, the researchers used “pre-compensate for nonlinear effects” approach using the frequency comb that unscrambles information at the beginning and fully restores at the receiving end of the optical fiber, removing the need for regenerators.

Instead of regenerators, UC engineers have hit upon the idea of eliminating periodic electronic regeneration leading to cheaper and more efficient transmission of information. “Our approach conditions the information before it is even sent, so the receiver is free of crosstalk caused by the Kerr effect,” says Prof. Stojan Radic at UC San Diego.

The breakthrough now leads to “wideband” instead of broadband as the next generation Internet revolution giving supercomputing speed to every mobile handset and PC.

Developed by Eduardo Temprana, a Ph.D. student and first author and Nikola Alic, another research scientist from the Qualcomm Institute, the new wideband project was funded by Sumitomo Electric Industries and Google, while the paper has been published in the journal Science.

What it Means?

The newly developed wideband can make the transmission of data at higher speeds possible and also reduce the burden of bandwidth on fiber optic cables. With the existing fiber optic cables, data can be sent via Internet at 12,000 kilometers of speed means sending an entire film in instant, without putting extra burden on cables.

Secondly, this may kill telecom operators to daily newspaper vendors in terms of cost collection. Even at $20 per month, all cable operators can provide the superfast internet to their customers, replacing the need for heavily priced broadband width for many IT companies and high-end data usage entities.

The saved cost of Internet may spill over into investments in other areas and the world economy may get a second-level booster.
