INVESTIGATION OF ALL-OPTICAL INVERTER SYSTEM WITH NRZ AND RZ MODULATION FORMATS AT 100 Gbit/s
Original scientific paper The paper presents the comparative investigation on non-return-to-zero and return-to-zero modulation formats for optical inverter gate at 100 Gbit/s. Various performances as eye pattern, extinction ratio and bit error rate at different bit-rate are compared based on suitability of data formats. It indicates that return-to-zero pulses are distorted in a similar pattern,...
متن کاملPerformance Analysis of 10G/2.5G Asymmetric XGPON Transmission using RZ and NRZ Data Formats
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-PO...
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 کاملPerformance analysis of inter-satellite optical wireless communication (IsOWC) system by using NRZ and RZ modulation
Free space optical communication provides a very important method for the satellites orbiting around the earth to communicate with each other. Inter-satellite optical wireless communication systems (IsOWC) are one of the important applications of FSO/WSO technology that will be expand in space in the near future. These systems provide a high bandwidth, small size, light weight, low power and lo...
متن کاملEffects of Modulation Techniques (Manchester Code, NRZ or RZ) on the Operation of Hybrid WDM/TDM Passive Optical Networks
In this paper, the performance and feasibility of a hybrid wavelength division multiplexing/time division multiplexing passive optical network (WDM/TDM PON) system with 128 optical network units (ONUs) is analysed. In this system, triple play services (video, voice and data) are successfully communicated through a distance of up to 28 km. Moreover, we analysed and compared the performance of va...
