Normally, in Ethernet World, bit rate is referring to both downlink and uplink separately. So, terabit Ethernet is likely referring to 1Tb up and 1Tb down. However, the PHY and LINK layer support 1Tb doesn't always mean a device can dump so much data into the link. 5nm is probably referred to physical limitation which is bounded by law of physics. I would love to hear from material or semi conductor professional to confirm.

Well said, Necessity is Mother of Invention! If the gas price goes beyond $10, we will only see Electric Cars on the road!

I would be happy with terabit speeds. Is that for internet upload or download? :)

He is probably correct based on technologies currently being used or under consideration or on the roadmap. But historically, these comments have always come to pass and be bypassed, essentially.

End of Moore's Law

Finally someone speaks out honestly about this. Broadcom CTO Henry Samueli at #ethernet40 celebration: Moore’s Law is coming to an end. Transistors will stop scaling around 5 nm and everything will plateau. I am comfortable we will get to terabit speeds but I’m not sure we will see petabit. You will see density of switch boards level off. It will change the dynamics of the entire industry. We still have another 15 years or so to enjoy but we need to prepare at some point for a network that doesn’t double bandwidth every two years." End quote. What do you think about them bones?!?

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.
