The technology would allow the data transfer rates between nodes connected to these systems to be from 200 to 400 Gbps. These DACs would take advantage of the capacity of long-distance fiber optic channels, and that would result in a benefit for all users.
The DAC is still a prototype, but during the event Solid-State Circuits Conference (ISSCC) that is being held in San Francisco, its developers explained that a previous version is already being used for commercial DACs that will be manufactured by Semtech Corp.
This solution could be vital to take on the growth in data consumption that has been experienced on the Internet for years: today the daily traffic reaches two exabytes per day, 20 million times higher than it was in 1992.
Another remarkable factor of this discovery is the fact that this converter achieves those results with remarkable energy efficiency, and Semtech is already producing it using a 32 nanometer integration process.
