They tried to lay fiber in 2in trenches instead of typical 6in trenches. Then left when it didn't work. This isn't Goliath beating David. This is David throwing a rock, missing, and going home.
- wincy 8y agoI’m not sure David and Goliath is an apt metaphor when Google has a market cap 4x that of a broadband competitor Comcast.
- Someone1234 8y agoMarket cap is only relevant if both companies had a singular focus. Google isn't investing heavily into Google Fiber, and certainly not compared to Comcast.
- sodosopa 8y agoDavid vs Satan is more apt
- quest88 8y agoIs there any particular two inch trenches were dug? Was it too expensive? Extra permits?
- teachrdan 8y agoIf I understand your question correctly, they used 2" trenches because shallower === faster. However, they were so shallow--and the surfacing material so brittle--that the fibers ended up getting damaged too often. So they corrected with slightly deeper trenches afterwards.
- vb6lives 8y agoShallower === cheaper
- MrEldritch 8y agoFaster also === cheaper, so "shallower === faster" implies "shallower === cheaper" anyway.
- Someone1234 8y agoThey were copying a Germen technique (curb trenching) but trying to cut costs even further[0]. Google called it an experiment. [0] https://www.youtube.com/watch?v=Wisrs03EkDM https://www.youtube.com/watch?v=Wisrs03EkDM
- quest88 8y agoThanks!
- AareyBaba 8y agoIs there any technical analysis or reports available online on why the trenches didn't work ? I've always wondered if we could use our network of roads to bring internet to the doorstep by laying lines just below the road surface.
- Faaak 8y agoTrenches _do_ work, but they must have a minimum depth (>20cm), not just 8cm ones like Google tried.
- drenvuk 8y agoYou don't need much technical analysis here. Shallow trenches break more easily, leading to higher maintenance costs. 2 inches is nothing.
- sbov 8y agoAt 2 inches its not even deep enough to survive a road repavement.
- Mr_Shiba 8y ago> technical analysis Probably not, but common sense should be enough. It is 2 inches, on a road...
- paxys 8y agoThey aren't exactly dominating in markets outside Louisville either.
- elliotec 8y agoI’m in Salt Lake City and they have the fiber coming to my house strung up on telephone poles, not sure what this “inches under ground” thing means or why it matters. Google fiber has been fantastic for us since day one and it’s sad they aren’t moving forward with it.
- sithadmin 8y agoGoogle tried a 'micro trenching' approach to laying fiber in Lousiville - basically, channels cut into pavement in which fiber is laid, then filled in with epoxy on top. As it turns out, Google's specific implementation of this in Lousiville was highly unreliable.

- mjevans 8y agoThe use of trenches, micro of otherwise, is for running in locations that either don't have the poles or for which (most of the US) the poles aren't actually owned by the municipality and rented under FRAND terms to anyone that wants to hang a wire (by licenced and bonded independent contractors).
- tedivm 8y agoIf you read the article that you're commenting on they make it pretty clear what this “inches under ground” thing means and why it matters.
- selimthegrim 8y agoDoesn’t he have four more?
- walrus01 8y agoThere is micro trenched surface inlaid fiber with grouting ALL OVER downtown Vancouver BC. It's been in successful operation for 15+ years. It is a lot deeper than 2 inches. Google tried to do the backfilling/slot filling with some sort of rubber compound or something that was not proper pavement grouting. Google and their contractor fucked up the OSI layer 1. The way it's done with the "teraspan" (company name) method in Vancouver BC is not economical to service individual residences, or small buildings, it's a set of networks built for several different companies' last mile fiber access networks to service major class A office towers in the downtown core. The diamond blade concrete saw + microduct + cable + slot filling setup is way too costly in dollars per meter of installed fiber to be used for something like Louisville.
