FTTH\GPON in Denver, CO.

It's finally happening, FTTH in West Washington Park. Just like Google Fiber, Century Link is also leveraging Gigabit-capable Passive Optical Networks (GPON) for its "Gig" service. In other words, sharing happens. But who cares, we're all sharing at some point in the line (infrastructure). About 50 yards away is where my piece of fiber connects to the Optical Distribution Network (ODN) aka beam splitter. Another 150 yards away from that is the Optical Line Terminal (OLT) aka a Central Office (CO). So, ONT->ODN->OLT. One thing I didn't expect, or rather completely forgot about is how the fiber is converted to copper. Seems there is a powered media converter built into the ONT. The downside of this is that it requires power from inside your house. So expect to have a small shoe box sized battery somewhere in your home with power in from you and power out to the ONT. 

Inside the ONT.

Using iPerf to a system on another ISP in CO I get 23.5Mb/sec. Taking into consideration all the factors in between like latency, peering arrangements, throttling somewhere in there, it's not bad. Testing NNTP and a bin download across 10 steams I easily max out the 40Mb/sec connection. That's right, 40Mb/sec. Why not 100 or even 1000? Because I can't justify paying 100+ a month for Internet.
