TeraSignal capitalized on this week’s OFC 2024 trade show to introduce its novel intelligent re-driver solution that addresses the evolving needs for scaling AI bandwidth in data centers.
The new TS8401/02 intelligent 400G (4x100G) PAM4 modulator driver is a CMOS solution with digital link training and monitoring for 800G linear pluggable optical (LPO) modules.
TeraSignal claims its new TS8401/02 intelligent modulator driver addresses the limitations of traditional LPO modules, which unlike DSP-based re-timers, have lacked the capabilities for automatic adaptation, digital link monitoring and link training, making them challenging to integrate, interoperate, and deploy efficiently. By leveraging the existing microcontroller (MCU) in the LPO module, the TS8401/02 automates essential adjustments and introduces link diagnostics and link accountability, transforming LPO modules into adaptive link-optimizing systems.
A key element of TeraSignal’s TS8401/02 IRD's design is its intelligent monitoring, diagnostics, and automation capabilities. It introduces new features, including a digital eye monitor for real-time link performance measurements and link training with host SerDes. It sets a new industry standard for optical module performance and reliability. This facilitates a closed-loop system that identifies and rectifies link issues in real-time, ensuring uninterrupted, high-quality data transmission across the board.
Also, TeraSignal said its CMOS implementation reduces power consumption by as much as 50% compared to existing Silicon Germanium (SiGe) solutions and significantly boosts link reliability and performance through statistical link monitoring and adaptive control capabilities.
“TeraSignal’s intelligent CMOS solution for LPO modules redefines high-speed interconnects, merging low latency and power efficiency with unmatched link performance measurement capabilities, diagnostics, and quick time to market,” said Dr. Armond Hairapetian, founder and CEO of TeraSignal. “We are committed to delivering IRD solutions with superior performance over fiber and copper interconnects.
TeraSignal is now shipping samples of the TS8401 and TS8402 re-drivers to early-access customers and partners. The company works closely with leading module vendors, integrating the TS8401/02 into their LPO solutions. The TS8401 features wire bond pads, while the TS8402 offers the same capabilities in a flip-chip version.
