Re: Don't you think Verizon is few years late?

said by odindvatri :

While everywhere we hear 50, 100 and 1000 speed, here in US we have happy folks who just got 30 megs? My guess with backbone which Verizon has , when they start offering TV , speed will fall. I wouldn't trust them in a long term. I might be wrong, but in my opinion the future is in wireless so Verizon installs they spend billions on will in the near future become obsolete. Keep copper if possible.
You're wrong. TV, Internet and Voice are on separate fiber light bandwidth ranges. Meaning, they don't interfere with each other.

You are correct. BPON is a RF overlay where Verizon is using basically the same setup as a CATV provider. All TV channels are modulated RF then put on a Optical Transmitter at 1550nm infrared light (invisible) The ONT on the side of the house converts the light back into a CATV lineup on a COAX in RF form using Frequency Division Multiplexing.

The Data portion is 1490nm and 1310nm for Upstream and downstream traffic.

All these Colors of light ride the same strand of fiber. Two Colors going from the Central Office to the subscriber and the 1310nm goes from all the subscribers back to the Central office. One can assume the downstream channel tells the end users what time slot to transmit back so they do not collide. AKA Time Division Multiplexing.
