Fujitsu shows an optical network technology that can send 1.2 terabits of data per second per wavelength of light. The technology comes with new digital signal processor, water cooling and machine learning that can monitor the various components of the connection.

The new digital signal processor is according to Fujitsu one of the reasons why network technology can achieve a speed of 1.2 terabits of data per second per wavelength of light. Among other things, the processor would compensate for the distortion of the signal causing a signal according to Tom’s Hardware four times further than before. The company also developed a water-cooled system that can be used for optical network technology, making it the first company in the world to have this technology in-house.

Fujitsu also improved cooling efficiency and power consumption, bringing power consumption to 120mW per Gbit/s. According to the Japanese company, this is the lowest energy consumption in the industry. The company also developed machine learning technology that can optimize power consumption and monitor the status of the optical network. The network technology equipment would be a third smaller and lighter than air-cooled alternatives. The new technology will hit the market early next year.

Update, 6.27 pm: The article originally stated that Fujitsu’s network technology can transfer 1.2TB/s data per wavelength, but this had to be 1.2Tbit/s. The article has been adapted accordingly.
