Someone understands the difference between backbone capacity and last mile access:) |

said by deepblackmag  :Thats not true. New DWDM allows up to around 120gbps. Check out the SAFE pipeline. In a few years africas new ipv6 infastructure will make us look like the redneck retards we have running the country. DWDM runs multiple "sonet" pipes on a single fiber. IE-- your example of 120 gbps would actually be 12 separate wavelengths each running 10 gbps or oc192 not a single wavelength at 120 gbps. (320-400 gbps second DWDM machines are not that uncommon-- 32-40 oc192's) So in single "beam" of light oc768 is as fast as you will see deployed-- however DWDM tech could allow someone to run multiple oc768 on a single fiber for even faster DWDM. |

Big difference between upgrading a backbone and running fiber to my front door, like they ought to be.

What's funny is us worrying about africas infrastructure. As if they will be needing any such thing any time soon. Get real. |

I guess I should have said manufacturable. I started working on OC-768 switches in 2000. It has taken 5-6 years for it to get to the point that you could sell a switch with the technology (i.e not a one off prototype). I suspect it will take just as long for OC-1536 or what-ever they call it to reach a mass producible state too. |

OC-768 is the top end of current technology right now, but on the other hand a typical MPLS switch might have hundreds of OC-768 ports (usually 4 per line card), so that is a alot of available bandwidth. |

I was thinking the same. 40 Gbps could be used up real quick with a bunch of HD channels. |

AT&T has been laying a good bit of fiber in our area but still no idea if they are going ot do something about the RT's so we can even get DSL time will tell. |

40 Gbps is not enough. If they're spending this kind of money anyway, they should invest in upgrading further. Bandwidth usage is going to skyrocket in the next few years. Spending a little more now would be smarter. |
