We have generated 4 x 100-Gb/s orthogonal WDM optical signal by employing polarization-division-multiplexed (PDM) return-to-zero (RZ) QPSK modulation format and tight optical filtering technique. The required optical signal-to-noise ratio (OSNR) at bit error ratio (BER) of 2 x 10(-3) for the 400 Gb/s orthogonal DWDM signal is measured to be approximately 22.8 dB/0.1 nm. After transmission over 1040-km standard single mode fiber (EDFA-only amplification, 80-km amplifier span and fully receiver-side electrical dispersion compensation), the measured BER for all the four orthogonal subchannels are smaller than 2 x 10(-3).
