Credo Technology buys Dust Photonics

The acquisition gives Credo a vertically integrated connectivity stack spanning SerDes, DSP, Silicon Photonics and system integration for addressing both electrical and optical interconnects across the full AI infrastructure buildout.

“Combining forces with DustPhotonics marks a defining step in Credo’s strategy to lead across the full spectrum of AI connectivity,” says Credo CEO William Brennan, “we’ve built a strong position in high-speed electrical solutions, and this move decisively expands that leadership into Silicon Photonics with best-in-class PIC technology that complements our ZeroFlap Optical Transceivers and DSP portfolio.”

DustPhotonics has developed a differentiated portfolio of SiPho PICs spanning 400G, 800G, and 1.6T, with a roadmap extending to 3.2T, that integrates key optical functions onto a single chip.

These SiPho PICs are deployed in transceivers at leading hyperscale AI clusters and are also in design for leading Near Port Optics (NPO) and Co-Packaged Optics (CPO) applications.

SiPho PIC technology is a foundational component of Credo’s ZeroFlap (ZF) Optical Transceiver platform. Bringing this capability in-house mitigates external supply dependencies, accelerates product development cycles, and creates a pathway to substantial cost structure improvement at volume.

Combined with Credo’s SerDes and DSP intellectual property and products, the acquisition creates an end-to-end optical connectivity platform.

Credo believes it has reached an inflection point in its optical business. With the addition of DustPhotonics, the company expects its combined portfolio of ZeroFlap Optical Transceivers, Optical DSPs, and Silicon Photonics products to generate greater than $500 million in optical revenue in fiscal 2027.
