GPON upstream capacity is not symmetrical to the downstream. Above a 
certain threshold, providers will sell less upload than download, 
depending on how many customers are provisioned on a given OLT.

XG-PON is symmetrical, but not as widely deployed.

Providers that deliver services over Active-E do not care.
