Paradigm Shift in High-Speed Interface Technology

The exponential growth in data center traffic is driving an increase in demand for cost and energy efficient interface bandwidth scaling. This creates a need for a paradigm shift in I/O technology that meets future connectivity requirements within data centers. Silicon Photonics (SiPh) based optical interfaces significantly improve I/O density by optimizing solutions along three vectors: Packaging density, speed per lane, and number of wavelengths per channel. Each vector must be independently optimized. This paper recommends a SiPh based optical I/O platform that merges mature silicon chiplet packaging and fiber connectivity to achieve the highest I/O efficiency for networking applications.
