    I never would have guessed the ONTs we deploy use PowerPC processors. From what I can tell, this is a PowerPC 405 CPU. These must run relatively cool since there is no heat sink, nor ventilation to cool these cards. They can get pretty hot on their own, and I don't imagine Kansas summers do these ONTs any favors.

    ONT? What's an ONT?
    Nevermind, it's the device that receives optical data from the fiber optic cable and translates that to electric data for TV, Internet, & Phone. Like Google Fiber. Interesting.

    My Alcatel ONT barely gets warm to the touch. Maybe it uses something more efficient than PowerPC :p

    Wow you have fiber optic service? That must be awesome!!! 1,000Gbit/s U/D!!! :D That's 125Mbyte/s! Faster than the typical hard drive! You can boot from the cloud!! :D

    Wow Google Fiber is amazing! Very slow work though and it will be decades before the world is covered. :( At least there is something :D
    Once fiber optic will be widespread enough, cable will be dead! No more wishy-washy troll ISPs. :D And we'll also have optical computers! One small box on your desk would be so many times more powerful than today's most powerful supercomputer which is the size of a whole building!!!!!!!!!!!!!!! :D :D :D Optics are the future!!! :D

    Fiber optic service doesn't necessarily mean fast...it's just an efficient way for the Telco and now the ISP to get data to your house.

    Ma Bell started running fiber optics from the Central Office a couple of years before Al Gore invented the internet. My subdivision(built in the late '80s/early '90s) has a big box up in the front that South Central Bell(later Bell South when they merged with Southern Bell, and now AT&T after they merged back with AT&T a few years ago) installed when the place was built. They ran fiber optics from the central office downtown to this box, and have copper running from it to the houses in the neighborhood. Running copper that far gets really expensive really fast, and after about 15-20 miles from the CO call quality starts to deteriorate pretty dramatically.

    When the local cable company decided to get into internet about 15 years ago, they redid everything out our way to fiber optic. They then got into the Telco game with VOIP. So, now we have one box running to our house with fiber optic coming in. It splits off to coax(for both TV and internet) and two-wire copper for telephone service. The box also has to replicate all the elements of a traditional telephone line(+24V for talk, 350Hz and 400mHz simultaneously for the dial tone, and 100V at 20Hz for ringing). The internet speed is governed by local load, and will never exceed what we've paid for them to provide.

    Oh so you have a limit. >:E But the fiber optic cable itself is very very fast and has a LOT of bandwidth. Enough bandwidth to give everyone free internet (people pay installation though of course).

    Charter has had fibre optics for YEARS spent over $2 billion to create fibre optics in all 13 states they provide service for. gotta say it aint that great its just a way for the cable company to **** you over for instance before we canceled our internet in favor of free net from a neighboring business, we had 60 meg internet it was never that fast we were lucky to get 10Mbps. The more people using the internet the slower it went (Cable modems work on nodes).

    Finally fed up we bought a Long Range wifi antenna, installed it in a window in the back of the house (until spring/summer when i can mount it up on a pole) and canceled our (what would of cost $51.99 a month) Internet service. The antenna paid for itself in less than a month.

    We actually run a fiber drop directly to each subscriber's home. FrI'm the ONT, we run Cat5e into the home to feed the network. All this technology is in rural Kansas...
