Underground critters love the taste of cable. Duct makes the geometry such that they cannot take a bite.

We do not have gophers in Michigan. We put everything direct buried in rural areas. In some cases we may plow in 12ct cable down a mile of road with only a few obstacles that need to be bored. That's about $1000 of cable. A mile of innerduct is about $2000 in material and is a big product to plow if you're plowing, or has to be drilled in (more expensive). In town we run duct, mainly because there are enough obstacles that we have to drill it all anyway. There are certainly benefits to duct, but it adds a lot of cost when you're looking at a rural area with maybe 10 houses per mile. Just my opinion, worth what you paid for it!

Plus with duct you can cut and pull out and go over and under anytime you want. Saves in splicing and figure 8 ing etc. Duct is worth the extra expense. And it is not really that expensive.

Direct is cheaper but damage is much harder, takes longer to repair, and increases your maintenance cost over time. With direct bury you have no ability to pull slack or add new handholes for access. In the event of a fiber cut without duct the repair usually involves exposing 100’ of cable on either side of the damage and splicing in a new section of cable which will require double the number of splices and splice cases versus duct where you can pull spare cable in.

Some of them are onetime costs, not related to mileage like planning, permits and the like. This is one reason costs are all over the map, because it depends on how many miles you can spread fixed prebuild costs. Others are ongoing costs which will keep eating at you, even after you finish construction. Various reporting requirements and paperwork, locates, repairs, maintenance, etc. Even when you have a brand new plant you have to budget for OPEX.

Rural direct plowed in good soil with no duct and nothing in the way? 12k is about as low as I have seen quoted. Road crossings, boring, rock, urban, rail crossings, pipeline crossings will all add to that number. > > Mark > > > > On Nov 17, 2016, at 5:52 AM, Lewis Bergman <[email protected]> wrote: > > > > I know we have discussed this before but I wanted a current cost for backhaul fiber per mile in the ground. > >
