Performance Analysis of 10G/2.5G Asymmetric XGPON Transmission using RZ and NRZ Data Formats
نویسنده
چکیده
In this paper, a fiber optic communication system has been employed using 10G/2.5G asymmetric XGPON architecture. In this system bidirectional optical fiber has been employed for upstream and downstream data transmission. The system performance has been investigated for non-return-to-zero (NRZ) and return-to-zero (RZ) data formats by varying the length of the fiber for co-existed GPON and XG-PON system. The results have been compared for NRZ and RZ formats for upstream and downstream data in terms of Q value and eye opening. It has been observed that RZ modulation format is superior compared to conventional NRZ modulation.

متن کاملEvaluation of Wavelength Division Multiplexing System using Different Modulation Formats
In this paper, we have demonstrated the eight channel WDM system using NRZ, RZ and duobinary modulation formats. The WDM system has been analyzed by varying the input power from 0 to 20dBm for different modulation formats in order to find the modulation format for a high data rate optical transmission system. Furthermore, it is found that duobinary modulation is much better than Return-to-Zero ...
متن کاملAdvanced Optical Modulation Formats in High-speed Lightwave System
In the next generation of lightwave systems, high speed datarate like 10Gb/s or 40Gb/s per channel is very attractive. In addition, to pack more channels into one single fiber, channel spacing is decreased from 200GHz to 50GHz or even smaller. The direct side-effect is that linear and nonlinear degrading effects will be severe in such high-speed lightwave systems. An optimal modulation format w...
