Hi,
optical cable for internet...
* one fiber may carry the brightness and color of one pixel.
* so if you want to build a cable to transmit the resolution of a HDTV screen you need 1920×1080 fibers in one cable . about 2 million.
This means a huge cable.
But you know it´s possible to watch streaming TV via internet. Over one single fiber. (OK, indeed one needs a second one for communication the other direction)
One fiber can transmit about 100MBits/s up to 10GBits/s.
For one HD video stream you need (at least) 5MBits/s.
This means one may stream 200 channels of HD video over one fiber (5Mbits/s and 1GBits/s).
Which one is cheaper?
