Fujitsu announced today Achieved Tbps+ speeds over fiber network communications, unlocking the ability to transfer six 25GB Blu-ray discs in one second.
The company says its latest photonics technology (expected to be available to the market by early 2023) will enable up to 1.2 Tbps per wavelength while allowing four times longer signal reach before the signal begins to decoherence. announced that it will unlock the With the deployment of 5G technology and the development of even faster communication protocols, the need to shuffle data efficiently and quickly becomes more and more important. This is what photonics is particularly passionate about.
Fujitsu claims breakthrough across the board. Not only are the signal reach and bandwidth-per-wavelength figures unprecedented, but the company has also managed to reduce power consumption to an industry-leading 120mW per Gbps.
This approach is integrative and not limited to materials breakthroughs. Fujitsu has designed a new optical network solution alongside the world’s first liquid cooling solution for optical networks. State-of-the-art digital signal processing LSIs (DSPs) are also deployed in self-contained solutions, combined with low-level machine learning capabilities for power and traffic optimization.
This last point is very important because, according to Fujitsu, optical networking systems are rarely optimized for their implementation environment and cannot easily adapt to changing conditions (such as signal or equipment degradation). According to the company, the implementation of machine learning systems will enable it to automatically capture and analyze the state of optical network components, such as optical fibers and optical transmission systems, with high accuracy, and make on-the-fly adjustments according to operational conditions. increase. .
All innovations have resulted in systems that are not limited to breaking records for the amount of data that can be transmitted. Fujitsu’s network solution also occupies one-third of the space of traditional air-cooled optical network solutions, and has greater operating capacity due to improved cooling systems.
According to the company, all these improvements have significantly reduced the network solution’s CO2 footprint (the company estimates a 70% reduction across manufacturing, logistics and operations). ‘Environmental Sustainability’ book.
