[Davisgig] Fwd: Municipal Fiber Feasibility Study Update

[Robert Nickerson]

Hi folks,

I put on emergency list moderation so this did not go out in a timely 
way. I'm resending it now so its at the top of your inbox


Thx

Hi DavisGIG folks,

As part of the City of Davis' municipal fiber feasibility study, a 
pre-engineering survey is being conducted to get a ballpark figure for 
the cost of building the network. Yesterday, the Finley Engineering team 
for that survey met with a room full of COD folks as part of a site 
visit. I attended as an observer for the Broadband Advisory Task Force 
and wanted to let you know some of what I learned.

The meeting was attended by representatives of Public Works, the City 
Manager's office, City IT and the City's Innovation Officer and 
vice-officer. Finley's two engineers reported that they're getting great 
assistance from the COD folks and are enthusiastic about their findings 
to-date.

They expect to recommend that the project be entirely undergrounded (not 
on poles, even in neighborhoods that have them), using directional 
boring. The effect on streets should be minimal. They anticipate that 
there will be no above-ground "lawn furniture" (pedestals), instead 
using small underground vaults similar to (and possibly often next to) 
the vaults used for water meters.

They're looking at a major backbone loop through the contiguous part of 
the city with extension loops crossing 113 and 80 to West and South 
Davis. Distribution nodes of the backbone would be located in 4-5 
locations. It looks like the city already owns all the locations we 
should need for that. De-commissioned wells are a particularly good 
possibility. Individual fibers would run from those locations to each 
premises. Distribution would probably be a mix of GPON 
<https://en.wikipedia.org/wiki/Passive_optical_network> and active, 
depending on the needs of the consumer/business at the end of the line. 
Switching from one to another would be as easy as switching electronic 
cards. The engineers are including residential areas that adjoin the 
city, but aren't part of it (El Macero excluded as they're doing their 
own with Comcast).

Individual units in Multi-Dwelling Units (aka apartment buildings) may 
be connected in many ways (or not connected at all if landlords don't do 
it), ranging from fiber in the walls to forms of ultra-fast DSL on 
pre-existing copper lines. That will largely be the responsibility of 
the owners.

Connections to single-family homes and businesses will go to network 
demarcation boxes, like those we already have for telephone, typically 
on the side of houses.

Let me emphasize that this is just some early information from the 
people doing the feasibility study. It is not complete engineering and 
it tells us little about whether or not we'll be able to come up with a 
business plan that works for Davis. But if you're like me, the details 
of possibilities are still exciting!
