66/34 is 2:1 or exactly the same as GPON (2.4 down, 1.2 up). We sell 1000
symmetrical on that GPON and the customers are happy. You would have much
less oversubscription with 100/100 on a 1.2 Gbps wireless with 66:34
down/up ratio, than we are doing with GPON and 1000/1000. We are also doing
128 customers on a single OLT port.

Remember that a single customer only adds a few Mbps peak to your bandwidth
usage.
