We achieved a record capacity of 7.68 Tbit/s in a single channel coherent Nyquist pulse transmission over 150 km with a 9.7 bit/s/Hz spectral efficiency. In this scheme, a 1.39 ps optical Nyquist pulse with a high OSNR was generated by combining a mode-locked laser and a highly nonlinear fiber at both the transmitter and receiver. In addition, we suppressed a nonlinear phase rotation at an EDFA in the transmitter by broadening the pulse width with second-order dispersion and recompressed it to the original pulse width before a 150 km transmission link. At the receiver, a Nyquist LO pulse was synchronized to a transmitted OTDM data with an advanced optical phase-locked loop based on the higher harmonics of the mode-locked laser mode. By employing these improvements, we succeeded in a bit error rate below 2 x 10-2 for all the tributaries. |
