| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have proposed an optical Nyquist pulse and its orthogonal TDM scheme for high-speed and high spectrally efficient transmission. We previously reported a 5.12 Tbit/s PDM-differential quadrature phase shift keying (DQPSK) transmission over 300 km at a symbol rate of 1.28 Tbaud, using a non-coherent Nyquist pulse. In this report, we present a 10.2 Tbit/s-300 km transmission that we realized by increasing the symbol rate to 2.56 Tbaud. We generated a 340 fs Nyquist pulse and newly developed its dispersion compensation up to fourth order and an ultrafast demultiplexing using a nonlinear optical loop mirror. We also report a 10.2 Tbit/s transmission with a spectral efficiency of 3.7 bit/s/Hz, which we realized by reducing the roll-off factor to zero. | |
