Let me know when 10G over coax actually happens. xGPON exists now.

Technically 10G GPON1 (10G down, 2.5G up, GPON backwards compatible) exists now and won't be commercially practical until sometime next year. Symmetrical 10G GPON2 (non-compatible) is a future standard that won't be practical until at least 2015. If you have enough cash active fiber can handle 100 Gbps now. ]]> http://www.dslreports.com/forum/Re-Fiber-Copper-27197773 Fri, 01 Jun 2012 12:36:45 EDT Re: Fiber > Copper http://www.dslreports.com/forum/Re-Fiber-Copper-27197547 said by somms:

Just need more of the motivated home-grown munis to step-up and get FTTH installed where the greedy incumbents have failed to keep pace w/technology. Copper cable has been obsolete and trying to keep pushing the digital envelope on this analog-era tech is fail! :huh:

Lovin' my FTTH BTW! :D

I wish but live in a state where muni-fiber is effectively banned. Unfortunately the federal government does nothing useful to promote FTTH like using the interstate commerce clause to strike down such state laws.]]> http://www.dslreports.com/forum/Re-Fiber-Copper-27197547 Fri, 01 Jun 2012 11:39:39 EDT Re: Fiber > Copper http://www.dslreports.com/forum/Re-Fiber-Copper-27195753 http://www.dslreports.com/forum/Re-Fiber-Copper-27195753 Thu, 31 May 2012 19:45:57 EDT Re: Fiber > Copper http://www.dslreports.com/forum/Re-Fiber-Copper-27195737
if you think about it the light in the room is digital. when the switch is on the light is on, that switch is in the 1 position, if the light is off its in the 0 position.

Though X-GPON has 4x the capacity so I guess fiber wins again :p]]> http://www.dslreports.com/forum/Re-Fiber-Copper-27195441 Thu, 31 May 2012 18:11:51 EDT Re: Fiber > Copper http://www.dslreports.com/forum/Re-Fiber-Copper-27194499 How Fiber Optic Cables Work
The traditional method of data transmission over copper cables is accomplished by transmitting electrons over a copper conductor. Fiber Optic cables transmit a digital signal via pulses of light through a very thin strand of glass. Fiber strands (the core of the fiber optic cable) are extremely thin, no thicker than a human hair. The core is surrounded by a cladding which reflects the light back into the core and eliminates light from escaping the cable.

A fiber optic chain works in the following manner. At the one end, the fiber cable is connected to a transmitter. The transmitter converts electronic pulses into light pulses and sends the optical signal through the fiber cable. At the other end, the fiber cable is plugged into a receiver which decodes the optical signal back into digital pulses.

Good luck with that.

Plus, fiber is analog, too. You have the Layer 1 connection, except it is with light instead of electricity. Also, there is only so much you can shove in one spectrum of light. That is why there is DWDM. It is kind of like adding multiple channels to an existing fiber. Same way with DOCSIS. Spectrum = Channel.

No one wants to build a new infrastructure when one already exists. That's the primary issue with most ISPs and why most of the country is stuck with Cable and/or DSL.

Shhh! Don't tell the investors some more progressive cable companies are considering expanding or replacing some of their existing cable plant with RFoG and I have no doubt it can be 1 or even 1.8 GHz.

and yet the way things are going at least here in the US most of the country will never see fiber. the investors have decided that there is gold in wireless and its time to let the hardlines decay.

Sadly, yes. Wireless is relatively cheap to deploy, and people have grown accustomed to paying high prices for wireless data, so there's a perception that the ROI will be good. Maybe, but, as usage goes up and people see wireless data charges start to climb, I think they are going to hit their spending tolerance limits pretty quickly. You're already seeing this happen, as folks resist buying more devices to add to their cellular plans, and that's why the carriers are moving to shared data plans. That will help for a while, but, if the value isn't there, consumers' appetite for wireless is going to decrease pretty quickly.

I think that the next big push for wired connections will be when we see more connected devices in the home. Security cameras, smart thermostats, appliances that monitor electric rates, etc.]]> http://www.dslreports.com/forum/Re-Fiber-Copper-27194058 Thu, 31 May 2012 12:10:38 EDT Re: Fiber > Copper http://www.dslreports.com/forum/Re-Fiber-Copper-27193985
