Found on Slashdot on Friday, 29 September 2006

Nippon Telegraph and Telephone has announced data transmission at a rate of 14 terabits per second over a single optical fiber. The paper claims the previous record was "about 10 Tbps." In the new experiment, NTT sent data over 160 kilometers (nearly 100 miles) of optical fiber, in 140 channels of 111 Gbps each.
Now that would be nice for P2P.
