1.6T PAM4
MaxLinear PAM4 DSPs enable next generation optical modules for data center and hyperscale cloud networks
Data traffic continues to grow exponentially in hyperscale cloud networks; requiring ever increasing server access and switch-to-switch interconnect speeds. Low-power, high-density optical modules that support high lane rates are needed to enable higher bandwidth.
