But, with the speed technology is moving, they are pretty often left behind. Today’s merchant silicon can deliver all the performance and functionality one may need. The differentiators lie in software.

In 2020 they delivered more 400GbE switch ports than probably anyone else out there. And they actually make the ASIC (unlike Arista) and lead with open software.

I’ve seen lots written about the affordability and availability of the ZR optics but not much in the way of details on their costs (both absolute and $/perf) and what kinds of volumes the hyperscalers need. Would be interested of you hsve any insight on that front!
