Abstract
AbstractIn this paper, the performance of passive optical network is analyzed and compared for different modulation formats such as non-return to zero (NRZ), return to zero (RZ) at 2.5 Gb/s bit rate with 16 optical network units. This system is investigated in terms of quality (Q)-factor, optical received power and eye height at different transmission distances. NRZ achieves maximum transmission distance up to 48 km having Q-factor of 6.18 and RZ achieves the maximum transmission distance up to 41 km having Q-factor of 6.21. Furthermore, it is found that NRZ modulation format is more superior and covers more distance as compared to RZ modulation format.
