 At the VLSI Symposium we will discuss a 60Gbps optical link which provides a new paradigm to interconnect components in a data center. Basically we are going to replace electrical links in the short reach interconnect from the rack to the top tier one switch. And this is going to be a revolution because from now on all the interconnects will be converted from electrical to optical in a data center which will provide much more bandwidth and much more energy efficiency. So the biggest challenge is that you have such a small signal which gets at your receiver and you need to amplify the signal without corrupting the information. So all we need to do is to make sure that we can reliably transfer data because in a data center you need bit error rate in the order of 10 to the minus 12 which means that in average if you transmit 10 to the 12 bits only one can be wrong. So this is the level of reliability which needs to be required to be able to deploy those transceivers in a real data center. So I think this is gonna start economically when optics was only running at low speed was not actually practical. Today when optics reach about 60 gigabit per second we are gonna reach the crossover point and optics will eventually be cheaper than electrical solutions. As a consequence of that we will see optics more and more in a data center and we hope to push the envelope even more. We are currently working on 70 gigabit per second plus. Hoping we can actually pave the way to a replacement of electrical links with optical links inside the rack. It was very tough it was the result of more than two years of work and we were extremely happy so we designed nominally for 56. We always give margin. 56 was a target for our internal IBM roadmap. We were able 60 and then every gigabit per second is a party so 64 was achieved but then we realized we were capable of doing it. So then it became the reality and now we are even more greedy and looking forward to go more and more. Eventually more than 70 gigabit per second in the near future.
