Overview
- Cisco says the 8223 delivers 51.2 Tbps using Silicon One P200 deep‑buffer routing silicon, with 800G coherent optics support and inline MACsec for secure long‑distance links.
- The company claims the P200 consolidates functions that previously required 92 chips, reducing system power use by about 65% versus comparable designs.
- Industry reporting and Cisco indicate shipments have begun to hyperscalers, with Microsoft Azure and Alibaba Cloud engaging as early customers.
- Executives say the platform is intended to stitch training clusters across multiple data centers that can be roughly 1,000 miles apart.
- The debut steps up competition with Broadcom’s Jericho family and Nvidia’s Spectrum‑XGS as latency, cost and operational complexity remain practical limits.
