Almost all of the major routes we use today for teleco/internet routing were laid or substantially upgraded then. Almost all the dark fiber laid was laid then.
The hilarious part? Most of the fiber laid could do at least 40gbit, thus the cost of upgrading a lot of the existing backbone could be as easy as just swapping the line cards on either side.
IMO, we may not actually need more fiber (outside of last mile usage, which this bill is directed at), but just better use of existing fiber. If you're wasting fiber on anything less than 10 gigabit, please stop. It costs you next to nothing to upgrade compared to what it cost a decade ago: upgrading to equipment that can handle 10GBase-LR/ER/ZR or OC-192/STM-64 or better is worth every dime.
Literally, if the US government passed a law stating, say, any fiber over 5 miles long must have a line rate of at least 10 gigabit, and heavily subsidize upgrading equipment that is simply too old to handle it, a lot of Internet speed WTFery would go away in rural and suburban areas.
You'd be surprised how many LTE/4G cell phone towers, DOCSIS 3.x headends, or modern ADSL2+/VDSL2/possibly G.Fast DSLAMs do not have 10gbit or greater backbones. It's just absurd in 2017 that we're using stuff that is 90s era at best.
