TeraSignal Introduces Cutting-Edge 4x200G Transimpedance Amplifier

On March 31, 2025, at the Optical Fiber Communications Conference (OFC 2025), TeraSignal unveiled an innovative product that is set to change the landscape of optical data transmission. The TS9801/02, touted as the world's first quad 200G PAM-4 linear Transimpedance Amplifier (TIA), integrates TSLink™ Digital Eye Monitoring (DEM) and adaptive equalization. This technological advancement aims to tackle the increasing demands for higher-density optical interconnects driven by artificial intelligence infrastructure, all while emphasizing energy efficiency.

Bridging the Gap in Optical Connectivity

The deployment of linear optics faces several challenges, particularly when traditional discrete TIAs lack built-in diagnostic capabilities. Network operators typically depend on their host systems to monitor and address link issues, which are more straightforwardly managed with re-timed receivers. The TS9801/02 addresses this gap, integrating essential digital diagnostics that promise smoother operations in large-scale data centers.

The patented fully differential architecture of the TS9801 ensures exceptional noise performance, power efficiency, and bandwidth, while minimizing crosstalk across four channels. The subsequent model, TS9802, elevates this capability further with advanced features like the TSLink™ Digital Eye Monitoring and adaptive equalization, which are otherwise absent in existing solutions.

Key Features of TS9801/02

These revolutionary devices boast several features that make them perfect for modern data centers:
1. Ultra-Low Power Consumption: Each channel operates at just 210mW, requiring 3.3V and 1.8V power supplies, allowing for energy-efficient operations.
2. Advanced Signal Integrity: By incorporating TSLink™ Digital Eye Monitoring, the TS9802 provides real-time performance diagnostics and optimizes signal quality across high-speed optical networks.
3. Adaptive Equalization: This feature enhances signal integrity, allowing data center operators to achieve consistent performance as channel conditions fluctuate.
4. High Linearity and Low Noise: The fully differential design enables exceptional performance in achieving crosstalk isolation while maintaining a high dynamic range.
5. Versatile Applications: The new TIAs suit various linear optic classes, including Linear Receive Optics (LRO), Linear Pluggable Optics (LPO), and more, offering broad versatility in deployment.

A Game Changer for AI Infrastructure

TeraSignal’s latest innovation comes at a time when optimizing data center operations has never been more pertinent. As AI workloads continue to grow, the demand for reliable and energy-efficient optical interconnects is on the rise. Dr. Armond Hairapetian, the founder and CEO of TeraSignal, noted the significance of this development, stating, "The TS9802 represents a major leap forward in AI infrastructure optical connectivity by delivering real-time link diagnostics directly into the TIA. With integrated TSLink™ Digital Eye Monitoring and adaptive equalization, we are introducing the industry's first intelligent TIA, allowing operators to scale to 200G/lane linear optical receivers while maintaining full link visibility and control over link performance."

Availability and Future Prospects

The TS9801/02 models are scheduled for sampling to select customers in Q2 2025. Interested parties are encouraged to visit TeraSignal at OFC 2025, Booth #3327, which will be held from March 30 to April 3 at the Moscone Center in San Francisco.
