British and Japanese experts have set a new world record for Internet speed. The speed indicator was previously unattainable 178 terabits per second (Tbps). Engineers from KDDI Research, University College London and Xtera have developed new technologies to transfer more data over the existing fiber optic network.
Most of the existing infrastructure is capable of providing bandwidth up to 4.5 THz, and some new technologies have raised it to 9 THz. The latest system increases the bandwidth to 16.8 THz.
To transmit more information without interference, a combination of signals is generated that change the intensity, phase and polarization of the waves. The hybrid system is the result of various combinations of existing amplifier technologies.
Since the test system uses an existing fiber optic setup, the integration of this technology will be relatively simpler and cheaper compared to other experimental studies in this area. That is, in theory, it is enough to update the amplifiers, without the need to replace cables.
Regular users will not yet be able to use such an Internet for the foreseeable future, but this precedent is an excellent example of the fact that the Internet and communications in general have a lot to develop.
The fastest commercial network is currently used in Japan and can transmit data at 10 Gbps. It is also ahead of other experimental devices, including the Australian-developed photonic chip, which only a few months ago achieved an impressive 44 Tbps and beat the previous record holder, the Japanese rig, which reaches 150 Tbps.
“While modern systems are capable of transmitting up to 35 terabits per second, we are working with new technologies that more efficiently use the existing bandwidth of optical fiber and allow us to break the world record of 178 terabits per second,” says the developer.
