“What our LPO is doing is benefitting greatly from what’s going on in Silicon One and the software there,” Gartner said. “For customers that especially are deploying Silicon One on both ends of the link, there’s a 30% or 50% power reduction.”
The key technology in Silicon One is its strong support for serializer/deserializer (SerDes) capabilities on its switching ASIC. The new G300 chip found in the 9000 and 8000 boxes features 512 lanes of 200 Gbps SerDes for a total switching capacity of 102.4 Tbps, supporting low-power interconnects with extended reach—500 meters or even 2 kilometers —is important for large-scale AI and GPU clusters, according to Gartner.
Another issue with utilizing LPO technology is the reliability of the optics involved– a topic Cisco has been pushing hard on. In a recent Network World article, Gartner said that Cisco conducted a reliability test for which it acquired 20 different optics from different suppliers. “These…
