Overview

Credo Technology Group (NASDAQ: CRDO) is the company that invented Active Electrical Cables, and its ZeroFlap family is the interconnect layer behind many large AI cluster back-end networks. ZeroFlap AECs are plug-and-play copper cables that replace direct-attach copper with superior bend radius, lighter weight and up to 75% less volume, while guaranteeing zero soft link flaps — the failure mode that disrupts the lossless RDMA fabric AI clusters depend on. The family spans 100G, 200G, 400G, 800G and 1.6T, with the 800G ZeroFlap AEC reaching up to 7 metres so hosts can be cabled directly to switches without optical conversion; 400G and 800G variants cover CLOS and SHIFT configurations between QSFP-DD, OSFP, OSFP-RHS and QSFP112 ends at 3.3V and 0–70°C. Alongside the copper line, Credo ships ZeroFlap optical transceivers (800G class) built on its silicon photonics PICs and DSPs for the same reliability goal at optical reach. For PCIe and CXL, the Toucan retimer is a protocol-aware PCIe Gen6 / CXL 3.x device with 32 bi-directional lanes — 16 upstream and 16 downstream — running at up to 64 GT/s per lane with a channel insertion-loss budget above 45dB at 16GHz Nyquist, 6.5ns latency in low-latency mode, first bit error rate better than 1E-9 before FEC, and flexible 1x16 / 2x8 / 4x4 / 8x2 bifurcation. Toucan has passed PCI Express 6.x compliance and joined the PCI-SIG Integrators List, and is targeted at AI GPU fabrics, PCIe riser cards and backplanes, PCIe AECs and PCIe storage servers. For the memory tier, Credo's OmniConnect addresses AI memory and chip-to-chip interconnect scaling, including the inference memory wall. All three lines expose telemetry through PILOT, Credo's Predictive Link Optimization and Telemetry platform, which adds real-time link health, diagnostics and fault isolation. Credo showcased the full portfolio, including 1.6T ZeroFlap AEC and Toucan Gen6 PCIe AEC with PILOT, at AI Infra Summit 2026 in Santa Clara.
