Title: Re: [AFMUG] Fiber - ROI
Chris,
We went with standard 1x2 and 1x4 splitters. If I remember, I'll post our diagram when I get to the office on Monday.

Here is a quick sketch of the optical tap split we use. Each handhole uses a custom ratio FBT splitter to peel off a small bit of light from the mainline fiber, and then a normal PLC to break that up further to the required number of customers. If you are at all familiar with CATV this is essentially the same thing that coax taps do, just with light. The appropriate FBT ratio has to be picked at each handhole, and it steps up in % as you go down the line.
You can chain as many as 15-20 of these taps in a line using just one mainline strand, depending on split ratio, distance, and GPON optical budget. We run ZTE using class C++ OLT optics and run this system out to about 30km and still can split to cover about 20 houses over a mile of road.
We normally run rural mainline direct buried. When your mainlin cable is 18 cents a foot 35 cents for duct just blows the budget plus it adds another work step blowing or pulling the cable into the duct.

Chris,
I would love to have you post a schematic diagram of your low count PON system.
Do you use duct or direct burial?

We do fiber in 5-20 houses per mile areas. You have to get the cost down as much as possible. We plow most of our mainline direct buried, often use a 12-count tonable flat drop as mainline on side roads. With the right GPON splitting topology you can feed several hundred houses on a 12-count fiber. If the area is rural enough to not have a lot of paved driveways you can cover a lot of ground fast plowing. Cheap electronics like ZTE or UBNT. Everythign fusion spliced because splicing labor is cheaper for us than the fancy connectorized systems.
Permitting cost will vary by area, our costs are $500 for the first mile and $50 per additional mile, one time fee.

I’m looking at running fiber to some very rural areas.
Even if I get grant funding to run it. How are those of you doing it making the ongoing ROI when you might have 5 houses each mile?
Pole rentals are $15-$17/ea per year.
Is trenching normally something you pay the state/county per mile? Per once permit?
Does anyone know of a company I can consult with that will design and engineer FTTH networks?
Chuck - are you still accepting folks to come down with you for a week to learn your ways of fiber?
