Typo: "using their own desperate and varied systems." Should be "disparate".

Oh, I thought they were desperate to get their products out to the market, and so desperately testing the systems. I would be desperate, too, if I had to do a 60,000 hour life test with only weeks to go.

Nice to see some sense of humor among us techies! I hope all manufacturers allow access to their products' LM-80 data. MP Divakar

LATEST ARCHIVED BROADCAST
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.
