I agree it is odd to make 100/100 the top speed. The fiber service I have from my local non-Bell telco offers 100/100, 500/500, and 1000/1000. FiOS where you can get it goes to 940/880.
The obvious guess is that their upstream bandwidth is underprovisioned, or maybe they figure 100/100 is all they need to compete in that particular market.
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. Mark.
