Factors driving PSM4 and silicon photonics for data center architectures

Brent Hatfield, Molex Inc.

Single-mode SiPh bridges the gaps caused by the dual requirements of longer distances and higher data transmission speeds. For many customers this technology provides a lower-cost, lower-power option for what can be referred to as medium-reach distances that is future-proof for the next generations of data transmission speeds. With a broad base of products both available and being developed by multiple suppliers, PSM4 and SiPh AOCs can be deployed today to enable new data center architectures, with the assurance that they’ll provide a path to cost-effectively meet future generation upgrade requirements.

Molex is a player in SiPh, so some bias is expected. Still, very convincing arguments.
