I am impressed that their measuring instruments have a precision that is (statistically significant-ly) smaller than a billionth of a second.
- sp332 15y agoHow do you think gigabit ethernet works?
- sliverstorm 15y agoI don't have the specs, but 100Mbit operates at 31MHz. Remember, quad-twisted pair. So it is likely 1Gbit operates at ~300MHz. Now, 10Gbit probably does operate with a period less than 1ns. (1 billionth of a second)
- sp332 15y agoOver Cat5e, it uses all 4 pairs and 2 bits per symbol, so it's only 125M symbols per second (per pair). I was thinking of fiber, which I think also uses 2 bits per symbol so it would need 500M symbols per second.
