DustPhotonics launches 800G and 1.6T PICs for AI and datacentres
The company says its new Tamar product family includes the industry’s first merchant 1.6T-2xFR4 and 800G-2xFR4 products with integrated optical multiplexer
DustPhotonics has announced Tamar200 and Tamar, two next-generation PICs that the company says further extend its merchant product leadership. Designed for AI workloads and hyperscale datacentre environments, the new 1.6T and 800G PICs aim to enable breakthrough levels of performance, density, and power efficiency.
According to DustPhotonics, 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 200G per lane, targeting next-generation 2xFR4 optical modules. Similarly, the Tamar PIC delivers two transmit channels of 400G-FR4 operating at 100G per lane.
DustPhotonics says both products include a low-loss athermal integrated multiplexer (mux) and the company’s 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 40 mW 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, and linear receive optics applications at reaches up to 2 km, the company adds.
