  1. Optical Interconnects for Computing Applications Mitchell Fields, Ph. D.mitch.h.fields@avagotech.com

  2. Evolution of high-bandwidth interconnects Throughout history, optical interconnects were adopted when they overcame limitations of electrical signaling: Distance / Bandwidth / Density / Power Computing For optical interconnects in computing environments, COST and POWER are the most critical metrics.

  3. Modules targeted at different design points

  4. MicroPOD: Driven by high-performance computing MicroPOD: 8.2mmx7.8mm 12-channel 10G Tx and Rx modules To build the world’s most powerful computing system, IBM required a novel optical interconnect. MicroPOD was designed for low cost and high performance. HPC Challenge: Unprecedented sustained computing power Partnership for differentiation IBM Power775 Datacenter in a rack:12 drawers / ~100TF IBM Hub Module: 28 Tx/Rx MicroPOD pairs (~6 Tbps I/O!) IBM Power775 drawer: 8 Hub modules
