A bit error ratio tester (BERT) is a device or software tool that sends known patterns of digital data through a communications link and counts how many bits arrive incorrectly, producing an error rate that measures the link’s reliability. Investors care because this metric reveals whether networks, chips or products meet performance and quality standards—poor results can signal increased costs, recalls, slower rollout or customer problems, while strong results support product claims and lower operational risk.
berttechnical
BERT is a type of artificial intelligence model that reads and understands written text by looking at words in both directions, like reading a sentence forwards and backwards to catch the full meaning. Investors care because BERT lets companies automate reading of news, filings, customer feedback and regulatory documents more accurately, which can speed decision-making, improve compliance and surface signals that might affect a company’s outlook—similar to hiring a fast, very thorough analyst for large volumes of text.
pam4technical
PAM4 is a digital signaling method that sends information by using four distinct voltage or light levels instead of the usual two, letting each transmitted symbol carry two bits of data. Think of it like a radio knob with four clear positions instead of just on/off; it boosts transmission speed without needing extra wires or spectrum but is harder to read reliably, so it matters to investors because it drives demand for higher-performance chips, better cables and optics, and can affect product costs, margins and upgrade cycles in networking and data-center markets.
rftechnical
rf (commonly written r_f) denotes the risk-free rate — the theoretical return on an investment with no chance of loss, often used as a baseline for valuing other assets. Investors use it like a yardstick: returns above this number compensate for extra risk, so it helps price stocks, bonds and option valuations and guides decisions about whether higher-return opportunities justify their added risk. Think of it as the safe deposit box interest rate against which riskier bets are measured.
latencytechnical
Latency is the time delay between when information or an instruction is created and when it is received, processed, or acted on by a market system or data feed. For investors, that delay can alter the price you receive, cause missed trading opportunities, or increase execution risk — like sending a text to buy an item and the seller acting a few seconds later after the price has changed.
oscilloscopestechnical
An oscilloscope is an electronic instrument that draws how voltage or current changes over time, like a live chart or a seismograph for electrical signals; engineers use it to watch a circuit’s behavior in real time. Investors care because oscilloscopes are essential for designing, testing and certifying electronic and medical devices—so their use reflects a company’s product development, quality control, regulatory compliance and capital spending, and demand can hint at activity in tech and manufacturing sectors.
hyperscalertechnical
A hyperscaler is a very large provider of cloud computing and data-center services that owns and operates vast amounts of servers, storage and network capacity to host other companies’ applications and data. Think of them as the electric utility for digital services: their scale cuts unit costs, enables rapid growth for customers, and creates high barriers to entry, so investors watch their market share, margins and capital spending closely.
xputechnical
XPU is a broad label for any kind of processor or accelerator chip designed to speed up particular computing tasks — from general-purpose CPUs to graphics, AI, or neural-network processors. Think of it like a specialized tool in a toolbox: the right XPU can make certain workloads run much faster and cheaper, so demand, production capacity and performance of these chips directly affect a technology maker’s revenue prospects, costs and competitive position.
Collaboration validates Point2 Technology’s innovative e-Tube™ multi-terabit interconnects using Keysight's high-speed digital test solutions, addressing critical power and bandwidth challenges in AI infrastructure
SANTA ROSA, Calif.--(BUSINESS WIRE)--
Keysight Technologies, Inc. (NYSE: KEYS) and Point2 Technology today announced a strategic collaboration to validate next-generation, multi-terabit interconnects designed to eliminate scale-up connectivity bottlenecks in artificial intelligence (AI) and machine learning (ML) data centers. Using Keysight’s high-speed digital test solutions, including the M8050A High-Performance Bit Error Ratio Tester (BERT) and DCA-X Sampling Oscilloscopes, the companies are validating Point2’s power-efficient e-Tube™ interconnect technology to meet the stringent performance and reliability requirements of hyperscaler AI infrastructure.
As AI workloads drive exponential bandwidth demand, hyperscalers face critical interconnect challenges when scaling up xPU clusters. Point2’s e-Tube™ technology uses RF data transmission over plastic waveguide and targets to provide up to 10x longer reach than traditional copper at comparable cost structure, while being 3x lower in power and cost, and 1,000x lower in latency when compared to optics. The e-Tube technology provides designers with an energy-efficient, high-density interconnect alternative to replace copper, and potentially eliminate the interconnect bottleneck in xPU clusters.
Keysight is providing comprehensive validation and characterization framework to ensure these new interconnects meet the stringent reliability and performance requirements of hyperscalers. As part of the collaboration, Keysight is enabling the industry to conduct early research and development on 3.2T interfaces by leveraging its unique 448 Gbps electrical signal generation capabilities, combined with advanced analysis using real-time and sampling scopes.
The collaboration leverages Keysight’s high-speed digital test solutions, including the M8050A High-Performance Bit Error Ratio Tester (BERT) and DCA-X Sampling Oscilloscopes, which are crucial for generating and analyzing complex 120 GBaud PAM4 signals required for 1.6 Terabit speeds.
Sean Park, CEO, Point2Technology, said: “A strategic partnership with Keysight gives us access to world-class engineering tools and support, allowing us to accelerate our e-Tube product development cycles. The confidence that comes from validating our e-Tube platform using Keysight’s rigorous test equipment is invaluable as we engage with leading hyperscaler customers globally."
Dr. Joachim Peerlings, Vice President of Network and Data Center Solutions at Keysight, said: “AI scale-up architectures demand disruptive innovation in physical interconnects. Keysight provides the industry’s trusted source of measurement truth, helping innovative partners like Point2 validate technologies quickly and confidently at multi-terabit speeds to achieve their next breakthroughs."
