Abstract
The performance of ASK over DCDM for up to seven channels is reported. The aggregate bit rate of 70 Gb/s is achieved with only 160-GHz modulation bandwidth. The clock and data recovery are realized at 10-GHz clock rate, which is very economic and efficient. At 7 � 10 Gb/s, the worst receiver sensitivity of�10 dBm, OSNR of 41.5 dB and chromatic dispersion tolerance of ±17 ps/nm are achieved. Whereas, for the best channel, the receiver sensitivity,OSNR, and chromatic dispersion tolerance are �23.5dBm, 29dB, and ±36 ps/nm, respectively.
