This morning, Credo detailed its 1.6T ZeroFlap Active Light Cable at the OCP Global Summit in San Jose, the industry’s first row-scale, wide-parallel optical interconnect aimed at AI scale-out and front-end networks. The pluggable cable pairs a dense array of micro-emitters and photodetectors with flexible fiber bundles, targeting up to 50m reach at a 12W draw per cable-end — roughly 30% less power than comparable active electrical cables — with 100 million hours MTBF and hitless failover through built-in channel redundancy. Shipping is slated for 2027, and Credo is demonstrating the architecture at its OCP booth this week.
The architecture splits each 200G lane into many low-rate optical channels running simple NRZ modulation, sidestepping the power and latency of DSP-based signal processing — a deliberate “slow and wide” inversion of the industry’s fast-and-narrow transceiver orthodoxy, and one Credo bills as 10x lighter than the AECs it displaces at reach.
We think the significance is market structure: Credo is carrying the reliability economics of its field-proven AEC franchise into optics precisely where copper runs out of reach and conventional pluggables are most power-hungry. If the 12W-per-end figure holds at 50m in production, the mid-reach tier of scale-out fabrics becomes a price-and-reliability contest Credo is positioned to win — and the 2027 ship date means the window for transceiver vendors to answer is now.
650 Group researches several of the technologies we covered in this blog, including Data Center Co-Location/Cloud, Enterprise, and more.
