Hardened carrier grade Ethernet gear appeared quite a time after PON gear did and until we got gear that could be deployed in cabinets the cost of the fiber plant being back hauled to the CO was much more expensive. Google decided to do GPON purely because of cost, they really wanted to do Active Ethernet but the economics didn't work out.

Only if we're talking about Ethernet, your WiFi network is almost never symmetrical.

Folks,
Let's not go overboard here. Can we remember that most corporate and campus (and, for that matter home) networks are symmetric, at least at the edges. Personally, I figure that by deploying PON, the major carriers were just asking for trouble down the line. It's not like carrier-grade gigE switches are that much more expensive than PON gear.
