Impact of the DPSK-OCDM modulation system on optical packet switching performance

The performance of a Differential-Phase-Shift-Keying Optical Code-Division Multiplexing(DPSK-OCDM) system with balanced detection is investigated in the case in which Gold codes are used. Allowing more optical codes to be supported, the performance in Packet Loss Probability of a DPSK-OCDM Optical Packet Switch, using both code and wavelength domains to solve output packet contentions, may be increased. In the proposed case study the increase is of two orders of magnitude when the offered traffic is 0.7.
