“What our LPO is doing is benefitting significantly from what’s occurring in Silicon One and the software program there,” Gartner stated. “For patrons that particularly are deploying Silicon One on each ends of the hyperlink, there’s a 30% or 50% energy discount.”
The important thing expertise in Silicon One is its sturdy assist for serializer/deserializer (SerDes) capabilities on its switching ASIC. The brand new G300 chip discovered within the 9000 and 8000 bins options 512 lanes of 200 Gbps SerDes for a complete switching capability of 102.4 Tbps, supporting low-power interconnects with prolonged attain—500 meters and even 2 kilometers —is necessary for large-scale AI and GPU clusters, based on Gartner.
One other problem with using LPO expertise is the reliability of the optics concerned– a subject Cisco has been pushing onerous on. In a latest Community World article, Gartner stated that Cisco performed a reliability take a look at for which it acquired 20 completely different optics from completely different suppliers. “These had been 100G and 400G optics on the time,” and all had been compliant with trade requirements, and but “none of these optics handed our stress take a look at,” he stated.
Cisco’s testing environments make adjustments to completely different situations, such because the temperature or humidity stage, or the voltage stage that the optic is seeing on the host, or the skew between the indicators coming from the host. “We do all of these issues in numerous mixtures,” Gartner stated.
Whereas optics may technically adjust to trade requirements, “what we all know is that in the event that they had been put right into a disturbing atmosphere … they wouldn’t carry out,” he stated, “and in order that’s the factor that we’re making an attempt to boost consciousness of for our clients.”
Shifting ahead, different Silicon One-based techniques are prone to assist LPO modules, Gartner stated. And finally co-packaged optics (CPO) may also play a giant function.
