Abstract :
We experimentally show the first demonstration of optically labeled 100-Gb/s packet polarization-multiplexing signals passing through four optical wavelength-selective switching (OWSS) nodes. In this architecture, the payload is generated by polarization-multiplexing return-to-zero octaphase-shift-keying format at 114 Gb/s, and 2.5-Gb/s on-off keying signal is used for the carrying label. By using the vestigial sideband filtering, the spectra efficiency is increased up to 1 b/Hz/s. The bit-error-rate performance for both payload and label are evaluated after passing through four straight-line OWSS nodes in this optical network.
