What it is

Copper cable with embedded retimer IC that extends intra rack electrical connectivity from 3m passive to 7m at 800G speeds

Why it matters

AEC is the dominant intra rack interconnect in NVIDIA NVL72 GPU clusters; lower cost/power than optical transceivers for short distances

Active Electrical Cable (AEC): technology and investment research

586 words · Vault research updated Jul 12, 2026

Technical bottleneck

Bottleneck type: supply/qualification
Technical constraint: HiWire retimer IC requires ultra-low latency (<1ns) and low power (<100mW) operation at 112/224 Gbps per lane
Economic constraint: TSMC advanced-node silicon fabrication; long hyperscaler qualification cycles (12-18 months)

Adoption

Driver: 800G/1.6T AI cluster scaling; each NVL72 rack requires ~576 AEC cables
Blocker: CPO (co-packaged optics) eventual displacement; hyperscaler insourcing of SerDes

Product categories

AEC cables, SerDes IP licenses, optical DSP ICs

Public companies exposed

CRDO (Credo), Marvell (MRVL), Broadcom (AVGO)

NOK (NOK)
ONDS (ONDS)

Validation signals

Hyperscaler volume AEC orders; 1.6T ramp qualification

Invalidation signals

CPO mass production launch; AEC-to-optics architectural shift
