TeraSignal Introduces World's First 4x200G TIA
Europe, Tuesday, 1 April 2025.
TeraSignal’s new TS9801/02 Transimpedance Amplifier revolutionizes AI data centers with 4x200G connectivity, enabling real-time diagnostics and enhanced optical performance for Europe.
Breakthrough in Optical Interconnect Technology
TeraSignal unveiled its groundbreaking TS9801/02 series at the OFC 2025 exhibition in San Francisco on March 31, 2025, marking a significant advancement in optical interconnect technology [1]. The new product represents the world’s first quad 200G PAM-4 linear Transimpedance Amplifier (TIA) with integrated TSLink™ Digital Eye Monitoring (DEM) and adaptive equalization capabilities [2]. This innovation arrives at a crucial time when hyperscale data centers require increasingly higher bandwidth and lower latency to manage massive data processing demands [3].
Technical Specifications and Performance
The TS9801/02 delivers impressive technical specifications, featuring ultra-low power consumption at 210mW per channel while operating from 3.3V and 1.8V power supplies [1]. The device incorporates a fully differential architecture with high-linearity and low-noise performance, ensuring excellent crosstalk isolation across its four channels. The differential transimpedance gain ranges from 150Ω to 2.5kΩ, with a 400mVppd output voltage in AGC mode [4]. The compact design measures 2.4mm x 1.2mm in bumped die form, with a 500um channel pitch [1].
Market Impact and Industry Response
This innovation comes amid growing demands in the optical circuit switching (OCS) market, which is projected to exceed $1 billion by 2028 [3]. Dr. Armond Hairapetian, TeraSignal’s Founder and CEO, emphasizes that the TS9802 represents a major leap forward in AI infrastructure optical connectivity, particularly through its real-time link diagnostics capabilities [1]. The technology is specifically designed to enable reliable deployment of low-power 1.6T LRO and LPO modules in AI infrastructure, addressing the increasing demands for higher-density optical interconnects and tighter power budgets [4].
Availability and Future Prospects
TeraSignal has announced that the TS9801/02 will begin sampling to select customers in Q2 2025 [1]. Industry professionals and potential customers can currently examine the technology at the Optical Fiber Communications Conference and Exhibition (OFC 2025) at the Moscone Center in San Francisco, where TeraSignal is showcasing the innovation at Booth #3327 through April 3, 2025 [4].
