Abstract

A new dispersion map is designed for three-level code division multiplexing (3LCDM) of a 40 Gb/s $$(2\times 20\, \hbox {Gb/s})$$ ( 2 × 20 Gb/s ) over 500 km $$(5\times 100\,\hbox {km})$$ ( 5 × 100 km ) standard single mode fiber. The results show that an 87.5 % dispersion compensation ratio was the optimum map for the 3LCDM system. The system performance is improved by 6 dB in optical signal-to-noise ratio, 6 dB in receiver sensitivity and 3 dB in self-phase modulation threshold. Based on these improvements, the 3LCDM performance is comparable to the available multiplexing and modulation techniques while offering simpler transmitter and receiver architecture.
