The Trend of DSP's Application in Data Center
The data center 100G has begun to be used on a scale, and the next-generation 400G is expected to begin commercial use by 2020. For 400G applications, the biggest difference is the introduction of a new modulation format, PAM-4, to achieve a doubled transmission rate at the same baud rate (device bandwidth). For example, the single-lane baud rate of DR4 used for transmissions up to 500m need to re...
