Transpacific Unity Fiber Optic Cable Leaves Japan
JoshuaInNippon writes "The 10,000 km (6,200 mile) long Unity fiber optic cable, funded by Google and five East Asian communication companies, left Japanese shores on November 1st to be laid along the northern Pacific Ocean floor. The Japanese end of the cable is expected to be fused to the American end sometime around November 11th. The cable, which was announced in February of 2008 at a cost of around $300 million USD, has the theoretical capacity of 7.68 Tbps, but will be set at a capacity of about 4.8 Tbps (supposedly equivalent to about 75 million simultaneous phone calls) during its initial use. When Unity begins full operation sometime early next year, it is projected to increase internet traffic capacity between the two regions by over 20%, a wonderful boost to transpacific relations!"

Even fiber optic cable is getting laid...
So I've got a bunch of cable laying around, figure I'll run my own line from Japan to California. How does that work, exactly? I assume the cable is protected in some extremely strong waterproof and snag-proof sheath, but do they really just roll it off the ship, let it fall to the ocean floor, and there it sits? Do they have to occasionally throw a repeater overboard as well? I've always been curious how we're actually able to have these outrageously long cables under the sea and that it works, and works well enough that I believe cables are still the preferred method of data movement, with satellites being a distant second.
Sweet, this will give me faster access to Hulu, Slacker, and all of the nice American websites.

How much of that cost is the cable?

On land rural jobs cost about $15K/mile. On land super-urban jobs cost about $500K/mile. The difference is permits, corruption, kickbacks, etc. Also scaling is important, "one job in Montana" may be hundreds of miles, and "one job in Manhatten" may be measured in feet, but the fixed costs are... fixed... so the cost per mile seems higher on the short jobs.
If you assume underwater fiber costs around as much as the total cost of cheap rural route, the 6200 mile route times 16K/mile equals about $100M. That makes sense, since the whole job is only supposed to cost about $300M.
Repairing fiber is somewhat more difficult than laying fiber because it's time sensitive. But then again they probably charge by the hour anyway. Since a "several day" repair job approaches $10M, if you assume that is 4 days at $10M total, that would be about $2.5M per day. The little row boat they're using is going to take about 40 days to paddle across the pond, 40 days * $2.5M a day conveniently works out to about $100M. That makes sense, since the whole job is only supposed to cost about $300M.
Add in the usual admin overhead, several multimillion dollar executive bonuses, engineering work, station gear at each endpoint, marketing and sales upfront expenses including slashvertisements, booze, coke, etc, I think they could blow somewhat less than $100M on that.
My labor estimate is probably about right for overtime repair work and a bit high for contracted construction work. My estimate for overhead may be a bit high. That means the cost of the cable itself probably is about $125M to $150M.
