DustPhotonics, which develops chips for transmit optical sub-assemblies (TOSAs) for 400 and 800-gigabit pluggable optical modules, has raised $24 million. The funding extends its Series B funding round.

"When you start ramping up products, you have to iron out the creases around supply chain, production, and everything else," says Ronnen Lovinger, CEO of DustPhotonics.

DustPhotonics has several customers and a backlog of orders for its 400 and 800-gigabit photonic integrated circuits (PICs). The company has also taped out its 200 gigabit-per-lane chip and will have products later this year.

The site has a striking view of a landscape also halfway between Israel’s flat coastal plain and the steep hills of Jerusalem.

Lovinger has been CEO of DustPhotonics since 2021. Before that, he was chief operating officer (COO) at Innoviz Technologies, joining the lidar firm after 18 years at Mellanox, now part of Nvidia.

DustPhotonics reveals its optical transceiver play

A start-up that has been active for a year has dropped its state of secrecy to reveal it is already shipping its first optical transceiver product.

The company, DustPhotonics, is backed by private investors and recently received an undisclosed round of funding that will secure the company’s future for the next two years.  

Product plans

DustPhotonics' first product is the multi-mode 100m-reach 100GBASE-SR4 QSFP28. The company will launch its first 400-gigabit optical modules later this year.

“We probably are going to be one of the first to market with [400-gigabit] QSFP-DD and OSFP multi-mode solutions,” says Ben Rubovitch, CEO of DustPhotonics.
