The 802.3af PoE allows up to 60W which is beneficial to all the edge clients like video cameras. With the use of midspans and PoE switches, it is possible to extend the 100m range. I agree that 1000BaseT can be beneficial to many consumers and can simplify power & data connections for home or small offices when it comes surveillance & monitoring. MP Divakar

To be clear, I'm talking about interface speed to PCs here. Switched Ethernet is the norm these days, meaning that the network core can be at higher speeds than any given end system. But I'm sure that as prices for 1G Ethernet interfaces drop, 1G will become the norm in motherboards and adapter cards.

Seems to me that adopting 1G Ethernet is usually, not always, a simple matter of price point. Same as 100M Ethernet, which is overkill for most people, and yet ubiquitous.

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.
