You might be surprised...
It is hard to be surprised when you have hard numbers. I run a network and unsurprisingly know exactly how much traffic my users cause. That number is currently about 2 Mbit/s peak aggregated per household. Do you need 100 Gbit/s instead of 40 Gbit/s? Yes you do if you carry traffic from more than 20,000 users or perhaps you have 10,000 users but want to plan for expected traffic increase over the next two years. But nobody plans their backbone so it can carry 20-30 Mbit/s aggregated per household. Well if you do, you have no competition, because otherwise someone else will figure out how to run a network at 1/10 the cost of what you do, and you will go out of business. Before someone points out the obvious: That math does not carry over to GPON OLT planning (too few users for the aggregation). You will have higher peak than 64x 2 Mbit/s on your OLT. But still, 2.4 Gbit/s shared among 64 users is currently more than sufficient that nobody is going to see any limits on their download rate, even during peak. And that is with users on 1000 Mbit/s plans. I have no idea what Google did or why. I have a feeling that my own hard earned experiences overrides any hear say on that matter... Of course what I am telling you might also be hear say (although directly from a primary source) so do what you think is best. I am just sharing our experiences in the spirit of this forum.
