## Cisco unveils new silicon and optics
Cisco Systems Inc. took to the stage at the Open Compute Project Global Summit today, unveiling a new suite of open silicon and optical networking systems.
## AI data centers face network bottlenecks
Networking has become a major bottleneck in AI data centers as frontier models require enormous clusters of thousands of graphics processing units.
## Silicon One G300 chip ships to customers
Cisco’s flagship 102.4-terabit Silicon One G300 chip is now being shipped to customers at volume alongside the new Silicon One P200 systems.
## Silicon One G302 chip features 51.2-terabit speed
The new Silicon One G302 chip is a 51.2-terabit top-of-rack networking switch with 200-gigabit serializer/deserializer interface and direct-to-chip liquid cooling.
## Nvidia and Cisco collaborate on repluggable optics
Cisco and Nvidia Corp. unveiled a new Ultra-Dense Small Form Factor Repluggable optical module handling 400-gigabit-per-second-per-lane electrical signals.
## New optics deliver 12.8 terabits per second
The new pluggable optics provide up to 12.8 terabits per second of capacity, four times the bandwidth density and 1.3 times the power efficiency of existing 200G optics.
## Cisco 8001 out-of-band network management
Cisco revealed a new out-of-band network management system powered by Silicon One A100 chips called Cisco 8001 for rapid network recovery during outages.
## Key takeaway

Cisco released new silicon and repluggable optics to scale AI network capacity without increasing power usage.
