Quantum optics developers take physics Nobel News & Analysis 10/4/2005 Post a comment Harvard University physics professor Roy Glauber will share the 2005 Nobel Prize for physics with John Hall of National Institute of Standards and Technology and Theodor Hansch of the Max Planck Institute for Quantum Optics.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
