Point2, a pioneering technology firm, has announced a groundbreaking collaboration with engineers at the Korea Advanced Institute of Science and Technology (KAIST) to develop an innovative cable solution that promises to enhance data center efficiency significantly. This breakthrough technology has been recently featured in the IEEE Journal of Solid-State Circuits. It further highlights Point2’s dedication to breaking through the limits of what data transmission is capable of.
Point2’s e-Tube cable harnesses state-of-the-art 28nm CMOS technology. This implementation is a wonderful step forward in NTNC’s ability to communicate data. This method allows for a highly parallelizable digital element that interfaces directly with GPUs. It includes a novel terahertz-frequency generator and a mixer that encodes data onto the terahertz signal. The end product is a powerful, flexible, and intensely capable transmission medium.
Advancements in Cable Technology
The e-Tube cable is noteworthy for its power 1.6 terabits per second. It accomplishes this astonishing speed by using eight thin, plastic waveguides. Each waveguide can carry 448 gigabits per second using two distinct frequencies: 90 gigahertz and 225 GHz. This incredible efficiency is what enables data centers to serve our society’s growing bandwidth needs while operating at a lower cost of power.
Point2’s clever design provides impressive space savings as well. The e-Tube cable occupies less than half the space of similar Active Electrical Cable (AEC). That’s what makes it such an attractive option for data centers which rely on being able to maximize their use of physical space. The e-Tube travels a phenomenal distance, extending farther than conventional copper cables by as much as 20 times. This cutting-edge technology allows you to send high-quality data at distances up to 20 meters, all without sacrificing quality.
David Kuo pointed out their many benefits compared to traditional methods. He stated, “You start with passive copper, and you do everything you can to run in passive copper as long as you can.” This just sheds light on the industry’s dependence on copper cables — servicing them continues to prove inadequate as bandwidth needs continue to grow.
Cost and Power Efficiency
Where Point2’s e-Tube cable really shines is cost-effectiveness. The system is just one-third the cost of conventional optical technologies. This capability is a great benefit to an organization looking to improve their data transmission capabilities without breaking the bank.
Besides being more cost-efficient, the e-Tube cable provides a major energy savings. Point2’s system consumes only one-third of the power required by optical solutions. This breakthrough innovation allows data centers to dramatically reduce their energy usage without compromising on high performance. This kind of cross-departmental efficiency is especially important now as organizations work toward the long-term sustainability of their operations.
Dave Welch noted the reliability of electronic systems over optical ones, stating, “Electronics have been demonstrated to be inherently more reliable than optics.” This reliability aspect, when combined with the requirement for zero packet loss, underscores the need for Point2’s technology in environments where performance and uptime are mission-critical.
Overcoming Limitations of Traditional Cables
With data transmission demands reaching terabit-per-second levels, copper cables are quickly hitting a hard limit they call the “copper cliff,” says David Kuo. We call this the copper bandwidth cap—the inability of copper technology to help achieve the amount of bandwidth we’ll need in the future. Point2’s e-Tube cable addresses these shortcomings directly. It does provide a compelling alternative that meets the most significant gap in current solutions.
Customers seek out fiber optic cables because of their high-speed capabilities and massive data capacity. First, lots of people tell us that they’re too complicated and too difficult to install. Your customers love fiber! They are bad at regular photonics and they hate the photonics, Welch noted, highlighting a key challenge in adopting some of today’s optical technologies.
Needless to say, Kuo feels that Point2’s innovative solution has a chance to reshape how data centers address their growing connectivity challenges. He imagines a day where institutions won’t have to depend on conventional optical wavelengths. Welch asked, “If I didn’t need to be at [an optical wavelength], where would I want to be?” He was particularly thoughtful about the changing nature of data transmission technologies.
Future Manufacturing Plans
Point2 looks forward to starting the manufacturing of chips that will power this exciting new 1.6-terabit-per-second cable, starting later this year. This move demonstrates Point2’s commitment to advancing technology and indicates a readiness to meet market demands for faster and more efficient data transmission solutions.
The new e-Tube cable might just be the biggest leap forward in decades of data center infrastructure history. Point2 features high capacity, low power consumption, and an extremely small physical footprint. This unique blend of power and versatility content delivery combined makes it poised to change the way we transmit data across networks forever.
