Abstract :
Experimental results are reported of polarisation-channel-interleaved carrier-suppressed RZ (PCI CS-RZ) ETDM/DWDM transmission of 8 × 40 Gbit/s over 320 km (2 × 160 kin) NDSF, with 0.8 bit/s/Hz spectral efficiency. An average system linear Q of 6.5 at a PRBS pattern length of 231 - 1 and tolerance to at least 50% degradation in orthogonality are demonstrated
