255 Tbps; Researchers at Eindhoven University of Technology (TU / e) in the Netherlands and the University of Central Florida (CREOL) in the United States reported on the publication of Nature Photonics the successful transmission of 255 Terabits / s (per second) fiber type, which allows 21 times more bandwidth than current 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 internet services and the emergence of increasingly demanding datacenters, the demand for bandwidth is expected to continue to grow sharply. For transmitting more data through today's glass fiber optics, one option is to increase the signal strength to cover the losses inherent in the use of the glass from which the fiber is made. However, this produces undesirable photonic nonlinear effects, which limit the amount of information that can be retrieved 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 reported in an Extreme Tech report, performance of this kind would allow 32 terabytes per second - sufficient to transfer a one-GB movie to 0,03 miliseconds, or transfer all the contents of one terabyte hard disk into 31 milliers . For example, the article highlights that 255 Terabits / s correspond to the total traffic observed on the Internet at peak time.
