Tamar Product Family Introduces Industry’s First Merchant 1.6T-2xFR4 and 800G-2xFR4 with Integrated Optical Multiplexer

DustPhotonics, a leading developer of silicon photonics solutions, has announced the launch of Tamar200 and Tamar, two next-generation Photonic Integrated Circuits (PICs) designed to enhance AI workloads and hyperscale data center performance. These new 1.6T and 800G PICs offer unprecedented levels of efficiency, density, and power savings. The live demonstration of these products will take place at the OFC Trade Show in San Francisco, CA, from April 1-3, 2025.

Introducing the Tamar200: The First Merchant 1.6T-2xFR4 PIC

The Tamar200 is the industry’s first merchant 1.6T-2xFR4 PIC, supporting two transmit channels of 800G-FR4. Each optical lane operates at 200Gb/s per lane, making it ideal for next-generation 2xFR4 optical modules. Similarly, the Tamar PIC delivers two transmit channels of 400G-FR4, each running at 100Gb/s per lane.

Both products feature a low-loss, athermal integrated multiplexer (mux) and DustPhotonics’ proprietary low-loss Mach-Zehnder Modulator (MZM) technology. These advancements eliminate the need for a Thermoelectric Cooler (TEC), significantly boosting system efficiency. Additionally, they are designed for external lasers, requiring only 40mW class lasers per wavelength.

Enhancing Industry Supply Chains and Efficiency

“We are excited to offer the first merchant 2xFR4 silicon photonics chip to the industry,” said Yoel Chetrit, CTO of DustPhotonics. “These products will help address ongoing Electro-Absorption Modulated Laser (EML) supply chain constraints.”

Designed for compact footprints ideal for OSFP and other high-density modules, both PICs support a range of applications, including:

  • Fully retimed (DSP) optical modules
  • Linear Pluggable Optics (LPO)
  • Linear Receive Optics (LRO)

These solutions enable data transmission over distances of up to 2km, further enhancing data center efficiency.

Availability and Demonstration at OFC Trade Show 2025

Both PICs will be available for sampling later this month. To explore these cutting-edge innovations, visit Booth #5321 at the OFC Trade Show in San Francisco, CA, from April 1-3, 2025.
