Talk on "Optical signaling for backplanes in network racks".

Speaker: Shri Krishnan Rengarajan from Cypress Semiconductors.

Title: Optical signaling for backplanes in network racks.

Abstract: Optical signaling has become ubiquitous today and has become the backbone of communication. The merits of high bandwidth and low loss over long distances has made optics the choice for long distance signaling. Optics has now made its advent for rack to rack and even intra rack connectivity in Datacenters, which are the hub of network activity consisting of 10s of 1000s of compute nodes. However, there is still throughput bottleneck encountered due to speed limitation of electrical signaling in the backplanes of network racks. This talk will discuss the possibities to bring optics to shorter distance contexts.
