It may be faster than current wired tech for home and office use, but it is definetely slower than current fiber optic systems. These can carry between 200 and 300 channels each one at 10 Gbit/s or about 100 channels at 40 Gbit/s
Mind that the system proposed by NTT is intented for point to point communication and not for LANs.
That frequency cannot be achieved using electronic oscillators. To generate frequencies higher than a few GHz you use optical systems.
A photodiode is used to beat two optical frequencies generated by lasers and thus obtain the intermodulation product that is needed. It is actually more complicated but that is the idea.
These systems may be easily more than $50000. A laser alone is about $15000. You can imagine this is not for home use.
I read the article mentioned in the original post and they talk about 2.5 Gbit/s and 10 Gbit/s which are standard speeds for telecommunication system trunking, I suppose this is the use it is intended for.
