Credo's Optical Bet: Is a $600M+ Revenue Opportunity Taking Shape?

Credo Technology Group Holding Ltd. CRDO recently generated $479 million in first-quarter fiscal 2027 revenue, up 9.6% sequentially and a massive 114.7% year over year. Management highlighted that its portfolio now spans connectivity from millimeters to kilometers, covering both optical and copper solutions. The potential opportunity is substantial because AI infrastructure is moving toward increasingly dense computing environments. Every additional generation of AI accelerators can require more bandwidth between systems, creating additional connectivity requirements.

If the number of servers or accelerators grows at a moderate pace, the connectivity content per system can rise significantly. Credo’s optical business is gaining momentum across optical DSPs, silicon photonics PICs and ZeroFlap optical transceivers. Optical DSP revenue hit a record in the fiscal first quarter, with strong demand for 50G and 100G-per-lane solutions. The optical business is expanding, with its system-level approach becoming increasingly important as AI networks shift to 1.6T and 3.2T solutions and scale-up architectures drive greater adoption of Near-Package Optics (NPO).

Following the DustPhotonics acquisition, Credo also recognized its first silicon photonics PIC revenue, with 800G and 1.6T products expected to ramp throughout the year. The integrated DSP-PIC platform could improve reliability, power efficiency and diagnostics while positioning Credo for the shift toward near-package optics. It now expects an inflection in the second half of fiscal 2027, with optical revenue topping $600 million and ZeroFlap Optics, silicon photonics PICs and optical DSPs each contributing more than $100 million, driving over 85% full-year revenue growth. Management expects second-quarter revenue of $525-$535 million, implying the company continues to grow at an exceptional rate.

CRDO’s Optical Edge Under Competitive Pressure

Marvell Technology MRVL optical DSP, switching and broadband businesses remain strong, with 800G demand solid and 1.6T ramping rapidly, expected to accelerate in fiscal 2028. Customers are initially using copper for scale-up networks, but as AI clusters expand, copper’s limited reach and bandwidth are pushing them toward optical interconnects and dedicated UALink, ESUN and NVLink switches. It is therefore investing heavily in next-generation optical interconnect and switching technologies. Marvell continues to see strong demand across optical DSPs, broadband analog, DCI modules and switching, with each tracking toward a $1 billion annualized revenue run rate. The scale-up opportunity remains large, with NPO, CPO and purpose-built switches supporting future growth.

Astera Labs ALAB is benefiting from rising demand for high-speed connectivity as AI infrastructure shifts toward larger rack-scale systems. Taurus, CXL, UALink, optical and custom connectivity programs broaden the longer-term content opportunity. Management plans to deliver UALink-enabled Scorpio X-Series switches in 2027, alongside signal conditioning solutions for copper and optical links. Its optical roadmap targets high-density fiber attach and near-packaged optics production in 2027, followed by co-packaged optical engines in 2028 and beyond. Third-quarter revenue is expected to be $540-$560 million, implying roughly 40% sequential growth, driven by Scorpio X-Series, Aries PCIe 6 and Taurus 800G shipments.
