Re: My Take on Lightspeed
Directional drilling may have to be reserved for rocky ground. It is overkill for areas that are just dirt. |

said by nunya  :The existing plant is in no condition to meet the 25 Mbps that AT&T says it will need. You need perfect cable. It aint perfect....Call me crazy, but I think that would be better spent on an upgrade rather than a re-grade. No argument here -- but the fact is "big-mo" is in-play (and SBC forgot to hire me). FTTN is the name of the game for-now. Fortunately most of the suburban neighborhoods that will likely first see FTTN have been built in the last 20 years -- and have relatively good F2 pairs and terminals. The current round of line-conditioning at least proves that SBC has their eyes "wide-open" as to what they're getting into.
Sure we all wish SBC would do what Verizon is doing with FiOS -- but I'm resigned to the facts -- and the improvements that FTTN will bring. The cablecos need some heat -- and LightSpeed will do that.
My earlier technical treatise on a future fiber upgrade for FTTN only means I accept the years it will take to get there and the architecture applicable to an FTTN upgrade at that time. We can always hope for a fundamental breakthrough in physics in the meantime  )
Remember, buried conduit costs are the real enemy here -- not SBC. I'm hoping that the concept of a "pilot mole" takes-off and solves the cost problem. The pilot mole concept involves pushing a tiny projectile through soil -- under streets, sidewalks and driveways. The resulting hole is just big enough to drag a thick pull-wire in the reverse direction. That cable is attached to a 2" slug mole that is then dragged-back, compressing the soil, on-return, for conduit placement, while being reeled back to the pilot mole site. The holdup is that current "pilot moles" aren't steerable -- like directional drills. It'll be much cheaper than the traditional [$10/ft] directional drilling that Verizon is doing now.

The existing plant is in no condition to meet the 25 Mbps that AT&T says it will need. You need perfect cable. It aint perfect. Far from it. It's chewed up, taped up, tied up, pieced together, "make it touch so it'll talk" stuff. Schlepping 1.5Mbps DSL across a pair is one thing. Trying to push 25Mbps? I'm very concerned. The amount of money being spent to "recondition" this stuff could be invested in new fiber. I've seen over $110,000 spent on a few blocks of 40 - 50 yr old plant. After over runs, I'm guessing $10,000 - $20,000 more.
Call me crazy, but I think that would be better spent on an upgrade rather than a re-grade.
FWIW, the existing plant is only being conditioned to 3kft from the node. Anyone past this point (even one span) is left off.
