Not some new fantastic technology, simple economics.

Henry Ford did not come up with any new fantastic technology either (he didn't invent the automobile nor the internal combustion engine), but how different would American life have been if he had listened to the naysayers who told him that there was no point in building millions of autos when there were no roads or gas stations to accomodate them? (Luckily for us, he didn't listen.)

No Bob, high speed serial communications that are byte oriented commonly use HDLC (though it doesn’t have to be byte oriented) which does not have start bits and stop bits on each byte. Instead it uses zero stuffing. If there are 5 or more consecutive ones it inserts a zero in order to protect what’s called a flag byte which has 6 consecutive ones with zeros on each end. The flag bytes are what provide both frame alignment and bit alignment.

See: http://en.wikipedia.org/wiki/HDLC

So the actual overhead is dependent on the data being sent over the link. In practice I believe it typically adds about 3% to the overhead. There’s additional overhead in the IP packets due to headers (routing information) and other encapsulating packet structures like Ethernet that are commonly used in network communications.

Okay, have it your way.

Don’t let the details get in the way...

Henry Ford made it affordable - the key to his success.

The cost of super fast communications to one’s house isn’t the fiber or technology related to fiber. It’s getting the fiber to your house - which this does absoluty nothing for. Like I said before it is economics. Ford solved the economic side of the equation.

Thanks for the link. The packet overhead is probably the reason that using a divide-by-10 seems to work out so close for the conversion.

Not w/ p2p from 10K other 40 Gbps users.

It’s all optical now. Copper is becoming obsolete.

I don't know that I would quite say that. Copper is on the way out for the most part, but there is still a lot of old technology in use. Where I live in SE Tennessee we are serviced by a telephone co-op. They are just now getting around to installing hi-cap lines. Prior to about a year ago, everything in their system was 2 wire POTS lines. No T-1 anywhere in their system until about 5 months ago. Ditto DSL. My brother lives over in NE Georgia. His telephone co-op finally got rid of the last mulitple party lines about 3 years ago. I've even seen stepper switches still in use in LA not too long ago.....
