I hope they can decide on one format. I wonder why they just dont use a fiber connection for all of the information. Working with fiber at SBC we have not yet found a limitation to the amount of data a fiber can carry. The limitation is the equipement on the ends deciphering the light. We have even put multiple wavelenghts on a single fiber feeding different equipement, such as our upcoming fttp and fttn. But alas that is for pocket protecting super smart people other than me.
