A team of researchers used a single computer chip to transfer 1.84 petabytes (PB) of data per second, about twice the entire Internet's traffic, and the equivalent of downloading about 230 million photos per second.
The breakthrough, which sets a new record for using a single computer chip to transmit data over a fiber optic cable, promises to lead to better-performing chips that can reduce power costs and increase bandwidth.
A multinational team of scientists has achieved a breakthrough in fiber optic data transmission, using a single computer chip to transmit 1.84 petabytes (PB) of data per second, about twice the entire Internet traffic and equivalent to about 100,000 downloads. per second 230 million photos. This breakthrough has set a new record for a single chip transmitting data over an optical cable and is expected to lead to better performing chips and improve Internet performance.
In the latest issue of the journal Nature Photonics, Asbjorn Arvada Jorgensen of the Technical University of Denmark and colleagues from Denmark, Sweden and Japan report that they used a photonic chip (optical components integrated into a computer chip) that splits the data stream on thousands of independent channels and transmits them simultaneously over a range of 7.9 km.
The research team used a laser to divide the data stream into 37 parts, each of which was sent through a separate core of the fiber optic cable, and then divided the data on each channel into 223 data blocks, which could be transmitted through fiber. optical cable in different colors without interfering with each other.
“The average global Internet traffic is approximately 1 petabyte per second. We are transporting twice that amount,” Jorgensen said. “That's an incredible amount of data that we send basically for less than a square millimeter [fiber optic cable ]. It shows that we can go much further than current Internet connections.”
Jorgensen points out that the importance of this unprecedented achievement is miniaturization. Scientists had achieved data transfer speeds of 10.66 petabytes per second using large devices, but this research sets a new record for using a single computer chip to transmit data over a fiber optic cable, promising a Simple single chip that can send more than existing chips. much more data, which reduces energy costs and increases bandwidth.
Jorgensen also believes that they can improve the current configuration. Although the chip requires a continuously emitting laser and separate devices to encode data into each output stream, these can be integrated into the chip, allowing the entire device to be as large as a matchbox.
The research team also speculates that if the system were resized to resemble a small server, the amount of data that could be transferred would be equivalent to 8,251 matchbox-sized devices today.
