TY - JOUR T1 - Duty-cycle division multiplexing (DCDM) A1 - Mahdiraji, Ghafour Amouzad LA - English PB - Elsevier YR - 2010 UL - http://discoverylib.upm.edu.my/discovery/Record/oai:psasir.upm.edu.my:11275 AB - A multiplexing technique, which is based on duty-cycle division, is proposed. The channel multiplexing and demultiplexing are performed electrically at the single user bit rate, which is very economic. In a three-user system (3×10 Gb/s), the simulation results show that the best receiver sensitivity value achieved is −30.1 dBm with an optical signal-to-noise ratio (OSNR) of 22.3 dB, while the chromatic dispersion tolerance ranges from 192 to 280 ps/nm. Migration from 30 to 120 Gb/s is achieved with the penalty of 6.4 and 5.2 dB in the receiver sensitivity and OSNR, respectively, for the worst user. ER -
