Ethernet 100 Gb/s

Lucent presented un product allowing transfers on Ethernet up to 100 Gb/s, using optical fibre.
To achieve this bandwidth, Lucent innovated: information is not transmitted using binary mode but with 3 signal levels, positive, negative and zero.
Using this new approach, an optical modulator is already commercialy available but reaches 'only' 40 Gb/s for the moment.
