multplied out you get 64gbit x 10000 = 640 terabits / sec

A single optical cable can carry at least 6.4tbit/sec, so 100 optical cables
can provide all the required dedicated bandwidth to serve the same stuff that
all those copper cables do. The cables are there now, and are simply being
lit up as needed by the various companies running them. I'm sorry, but the
times when the data amounts used for voice seemed big are over. In the
relatively
near future the data passing over the Net will dwarf what the phone carriers
deal with now.
