Abstract :
We have experimentally demonstrated how to generate 100-Gb/s packet signals with spectral efficiency higher than 1bit/Hz/s for the first time. The optical packet with 3.125-Gb/s label and 100-Gb/s return-to-zero differential quadrature phase-shift-keying payload are generated by using optical carrier-suppression and separation and vestigial sideband filtering techniques. The performance of transmission and label erasure has also been evaluated.
