That's the passive component, the optical splitter cabinet. They can be on boxes or in vaults underground.
The actives however are in ground-level cabinets.

OIC.
Let's hope it's a quick approval process. Once people realize what they'd be getting...?

Read that the Sonic.net application for 188 boxes is for the Richmond district. I don't know how many homes can be connected to a single box, but it seems like locating boxes in larger apartment buildings would be viable.

From what i read the 188 boxes would cover most of the city. At&t wanted to install 726 boxes for there fiber to the node -- they would run fiber to there older copper wire boxes and not to customers houses. Since sonic is using fiber to the home -- pulling fiber to everyone house they will need less boxes on the street.
"The trial will require one utility box, and a full deployment would require an estimated 188"

That's an interesting difference in how the boxes are deployed compared to AT&T. With about 350,000 households in San Francisco, 188 boxes would mean about 1 box for every ~1900 households (assuming a city-wide deployment). Dane, are you able to fill in some more detail on this, or is it all a little too preliminary?

With an FTTH deployment, in a PON configuration, we need about one shelf (an Adtran TA5000) for every ~2000 homes. This is why it's roughly 188 cabinets to serve the city - a single chassis fits in each cabinet.
