The entire undersea cable comes down to this — four tiny fibre optic cables. Between them these cables carry up to 1.28 terabits of data, which Telstra says is equivalent to 160,000 concurrent high definition television channels.
The cables transmit at an optical wavelength of around 1500nm, according to David Piltz from Telstra. That's the infrared region, and so it would not be visible to the naked eye. In a manner similar to tuning in a TV, the fibre optic system uses 64 unique frequencies within this range to transmit high volumes of data.

That's all kinds of funny!!
