Abstract :
Coherent optical interleave-division multiple-access (OIDMA) has been recently proposed for next generation passive optical network (NG-PON) systems. In this paper we present a performance evaluation and comparison of coherent OIDMA and coherent optical code-division multiple-access (OCDMA) PONs in terms of ONU launch power, PON reach, bit error rate (BER), user bit rate, and number of users. Results reveal that OIDMA out-performs its counterpart in all aspects. Particularly, high user loading compared to OCDMA.
