Credo's first 1.6T active linear cable uses micro-VCSEL instead of microLED, putting the preferred optical technology into that product. Credo has finally acknowledged the pivot, and micro-VCSEL remains the much-favored approach. x.com  x.com  x.com 

Credo's leading AEC position and vertical integration keep its optics thesis bullish despite SpaceX moving away from 1.6T AECs. That shift is a genuine risk, but xAI has been in Credo's AEC ecosystem the longest, which could support ZeroFlap optics and its telemetry software. Credo's VCSEL-based ALCs were still ramping toward 2027, giving it another route as customers move to transceivers. x.com  x.com  x.com 

MaxLinear's 1.6T roadmap threatens Credo's dominant AEC position with a specific share target. MaxLinear targets 20–30% of the 1.6T active electrical cable cycle, where its management estimates Credo has 93–99% share, initially across 1–2 US data centers. MaxLinear also reports 1.6T DSP and TIA design-win commitments, with initial revenue expected in 2027 and a stronger ramp in 2028. That competitive concern is behind Credo's pre-market drop. x.com 

Credo's new 1.6T ZeroFlap Active Light Cable extends its copper-cable strengths into a larger optics market. Targeted for shipment in 2027, it promises up to 50m reach, 30% less power than comparable AECs, 10x lower weight and 100M hours MTBF. These are targets, not proven results; there are no confirmed hyperscaler wins yet, and adoption by those large customers is what matters most. x.com  x.com 

MicroLED's poor prospects and growing expert enthusiasm for VCSEL could put ams OSRAM on more investors' radars. An ams OSRAM optical-interconnect executive says a 1.6T active linear cable was demonstrated using the company's micro-emitter engine with Credo's help, and their short-reach micro-optics partnership continues. x.com  x.com  x.com 

Credo looks exposed as networking becomes AI's next bottleneck and Nvidia locks down optical fiber for scale-up, scale-out and scale-across links. MicroLED is readily available and a good contender for scale-up and potentially scale-out, with many Asian suppliers pivoting into it. x.com  x.com 

Optical transceiver demand exceeds supply, and 1.6T lifts revenue per module for suppliers able to qualify capacity. Applied Optoelectronics raised at least $1.62B through 2026 ATMs; its last reported monthly capacity was 200,000 modules versus a year-end target above 650,000. Credo expects over $600M in FY2027 revenue across optical DSPs, PICs and modules, not modules alone. Shipments, yields and margins must prove out. Lumentum and Coherent already price in much expected growth. x.com 

Credo is well placed if the US restricts Chinese optical transceivers from 3.2T, because it now has a full non-Chinese optical stack. Its $750M DustPhotonics acquisition brought in-house silicon photonics for 800G, 1.6T and 3.2T, including co-packaged optics, alongside its own DSPs and SerDes. If optics supply tightens, more short links stay on copper, which is Credo's AEC business. Management already expected optical lines to top $600M next year before this. x.com 

MaxLinear's planned 1.6T AEC entry is too distant to justify the scale of Credo's selloff. Credo still has an estimated 90%+ AEC share and relationships with five of six major hyperscalers; MaxLinear expects initial revenue only in 2027 and a more meaningful ramp in 2028. Competition bears watching, but the market looks to be overreacting and Credo is starting to look ridiculously cheap. x.com  x.com 

Credo was wrongly dismissed as a copper-era connectivity play, and analysts are finally recognizing its optical roadmap. Per @wallstengine, Evercore ISI initiated at Outperform with a $325 target, saying Credo will increasingly be seen as a broad copper and optical AI-connectivity play through optical DSPs, silicon photonics ICs, microLED cables and especially ZFOptics modules, taking the same systems approach as with AECs. The market had decimated it in late 2025 as a horse-and-buggy name. … Show more
