Abstract: s paper reports the simulative analysis of NRZ, RZ, carrier-suppressed RZ (CSRZ) and duo-binary (DB) modulation formats for optical code division multiple access (OCDMA) system for two different types of encoders at 10 Gbps. The investigations reveal that highest Q2(dB) of the order of 16.5;14.5;6.2 and 3.8 has been obtained when we use combination of optical filters and time delay components as optical encoders in OCDMA system for CSRZ, DB, RZ and NRZ formats respectively. It is also observed that for fiber Bragg grating (FBG’s) as optical encoders, Q2 (dB) of the order of 17.7;11.8;7 and 4 is achieved in case of DB, CSRZ, RZ and NRZ formats respectively. CSRZ and duo-binary formats have shown the robustness over other formats for OCDMA system using filter, time delay components and fiber Bragg gratings (FBGs) as optical encoders respectively. The maximum eye opening in case of these formats further proved their efficiency.
