DustPhotonics Expands Silicon Photonics Portfolio with 2xFR4 Products for AI and Hyperscale Data Centers

Tamar Product Family Includes Industry’s First Merchant 1.6T-2xFR4 and 800G-2xFR4 Products with Integrated Optical Multiplexer
MODI’IN, ISRAEL – 1 April , 2025 – DustPhotonics, a leading developer of silicon photonics solutions, today announced Tamar200 and Tamar, two next-generation Photonic Integrated Circuits (PICs) that further extend the company’s merchant product leadership. Designed for AI workloads and hyperscale data center environments, the new 1.6T and 800G PICs enable breakthrough levels of performance, density, and power efficiency, and will be on display during a live demonstration at the OFC Trade Show in San Francisco, CA from April 1-3, 2025.
The Tamar200 is the industry’s first merchant 1.6T-2xFR4 PIC. The device supports two transmit channels of 800G-FR4, with each optical lane operating at 200Gb/s per lane, targeting next-generation 2xFR4 optical modules. Similarly, the Tamar PIC delivers two transmit channels of 400G-FR4 operating at 100Gb/s per lane.
Both products include a low-loss athermal integrated multiplexer (mux) and DustPhotonics’ proprietary low-loss Mach-Zehnder Modulator (MZM) technology, eliminating the need for a Thermoelectric Cooler (TEC), and dramatically improving overall system efficiency. The products are designed for external lasers and require only 40mW class lasers per wavelength.
“We are excited to offer the first merchant 2xFR4 silicon photonics chip to the industry,” stated Yoel Chetrit, CTO of DustPhotonics. “We believe these products will play a significant role in relieving some of the ongoing EML (Electro-Absorbtion Modulated Laser) supply chain constraints in the industry.”
Both PICs are designed in a compact footprint ideal for OSFP and other high-density modules and can be used for fully retimed (DSP), Linear Pluggable Optics (LPO), and Linear Receive Optics (LRO) applications at reaches up to 2km.
The chips will be available for sampling later this month. To learn more, visit our team at Booth 5321 at the OFC Conference between April 1-3, 2025 at the Moscone Center, San Francisco, California, USA.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
