China counters U.S. invisibility cloak News & Analysis 9/3/2008 Post a comment Chinese researchers, fearful that a U.S. invisibility cloak could hide objects from view while also blinding anyone inside, have devised what they call an anti-cloaking layer that solves the latter problem.
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.
