Abstract

Large enterprise and hyperscale datacenters are presently undergoing a technology transition from 100 Gb/s to 400 Gb/s machine-to-machine connectivity. Soon, 800 Gb/s and 1.6 Tb/s interconnects will be required. The state-of-the-art and future technical directions for optical interconnects in datacenters are reviewed. Particular attention is given to cases where copper and fiber connections are technically and economically competitive or soon will be – in fiber-to-the-server and disaggregated chassis Ethernet switch applications. Further attention is given to the impact of silicon photonics and the co-packaging of optics with Ethernet switching ASICs.
