255 Tbps; Eindhoven researchers University of Technology (TU/e) στην Ολλανδία και του University of Central Florida (CREOL) στις ΗΠΑ ανέφεραν σε δημοσίευση στο Nature Photonics την επιτυχή μετάδοση data- a record of 255 Terabits/s (per second) through a new type of fiber, which allows 21 times more bandwidth than today's communication network data.
According to a Dutch university report, this type of fiber could be a solution to the growing need for bandwidth.
Due to the spread of online services and the emergence of increasingly demanding networks datacenters, the demand for bandwidth is expected to continue to skyrocket. To transmit more data over today's glass optical fibers one option is to increase the strength of the signals to cover the losses inherent in using the glass the fiber is made of. However, this produces unwanted photonic nonlinear effects, which limit the amount of information that can be recovered after transmission.
The team of researchers from the two universities, led by Dr. Chigo Okonkou, assistant professor at the Electro-Optical Communications (ECO) research team at TU / e and Dr. Rodrigo Amizkua Korea, a researcher assistant professor in microstructured fibers at CREOL, demonstrated the possibility of a new type of fiber to increase the "capacity" / potential of transmission and possibly face the upcoming so-called "capacity crunch". The new fiber has seven different cores through which light can travel, instead of one that exists in today's sophisticated fibers. By comparison, this is the difference between a seven-lane boulevard and a one-way street. Also, two additional orthogonal dimensions for data transmission are presented in the paper - three cars that move one on top of the other in the same lane. By combining these two methods, a gross transmission throughput of 255 Terabits / s is achieved - more than 20 times from the current 4-8 Terabits / s standard.
As noted in a related article by Extreme Tech, performance of this kind would allow speeds of 32 terabytes per second—enough to transfer a one-GB movie in 0,03 milliseconds, or transfer the entire contents of a one-terabyte hard drive in 31 milliseconds. Indicatively, the publication underlines that 255 Terabits/s corresponds to its total traffic observed on the Internet during peak hours.
