This paper is the performance of Optical Code Division Multiple Access (OCDMA) system is studied using Differential Phase Shift Keying (DPSK) with Balanced Detection (BD) and optical thresholding. For the OCDMA- DPSK receiver, the performance parameters bit error rate (BER), receiver sensitivity and spectral efficiency for asynchronous multiple access network are evaluated and compared with on Off Keying (OOK) modulation. Analysis of the system performance limiting issues such as Multiple Access Interference (MAI) and signal interference Beat Noise (BN) are carried out and genuine approximation model is derived for the comparison.
