## USFP delivers 400-Gb/s speeds
USFP provides 400-Gb/s full-duplex data rates over 16 lanes with 32 in the future, achieving transmission rates from 6.4 tb/s up to 12.8 tb/s.
## USFP improves power efficiency
USFP has approximately 1.3x the power efficiency of OSFP modules supporting 200-Gb/s without requiring liquid cooling.
## USFP matches OSFP footprint
USFP matches the footprint of today’s OSFP transceivers, making for an easier transition than Arista’s XPO solution.
## USFP competes with Arista’s XPO
Cisco and NVIDIA have set up a competitive alternative to Arista’s eXtra-dense Pluggable Optics (XPO) solution.
## Cisco’s full-stack strategy
Cisco President Jeetu Patel promoted a full-stack, co-designed platform approach combining silicon, high-density systems, optics, software, and operational expertise.
## Cisco Nexus One architecture
Cisco’s networking architecture unifies Silicon One-based switches at the front end with NVIDIA Spectrum-X switches at the back-end.
## Silicon One P200 chip
Cisco’s Silicon One P200 chip with 51.2 tb/s switching capacity is adopted by Microsoft and Alibaba for AI networking.
## Alibaba uses P200 in Quantum Cat
Alibaba packed Cisco’s Silicon One P200 into its Quantum Cat router with SONiC operating system.
## Silicon One G300 chip
Cisco’s 102.4-tb/s Silicon One G300 chip is now available for customer sampling with some systems shipping.
## Silicon One G302 chip
Cisco’s 51.2-gb/s Silicon One G302 chip functions at top-of-rack deployments for scale up or scale across infrastructure.
## SONiC Live Protect feature
Cisco announced Live Protect for Cisco-validated SONiC on Nexus One architecture, available in Q2 2027.
## Cisco 8001 management system
Cisco unveiled the Cisco 8001, a SONiC-based out-of-band network management system for simpler operations during downtimes.
## Cisco strategy shows results
Cisco’s stock price grew over 100% in five years and over 70% in the last year, reflecting its full-stack strategy.
## Key takeaway

Cisco introduced 400-Gb/s USFP transceivers and Silicon One chips to improve AI networking efficiency at OCP Global Summit 2026.
