Abstract:
The important thing to consider in the process of sending optical fiber network signals is theselection of line coding types. Line coding is a process of converting digital data into digital signals sothat they can be transmitted in optical fiber networks. Line codings commonly used are NRZ and RZ.Therefore, this research discussed the comparison of the performance of NRZ and RZ line codings infiber-optic networks in terms of Q-Factor, BER, and Eye Diagram. The result of this research was thecharacteristic form of the electric signal line coding NRZ with one data element using one signalelemen

Abstract:
This paper proposes a Manchester return-to-zero on–off keying (M-RZ-OOK) modulation for free-space optical (FSO) communication. M-RZ-OOK modulation is achieved by introducing Manchester coding into the RZ-OOK format. M-RZ-OOK has the features of phase-flipped impulse series in the spectrum. Therefore, normal and inversed channel state information (CSI) can be extracted by applying a local oscillator (LO) with the frequencies of impulses, respectively. These extracted CSIs can be applied to realize adaptive threshold decision (ATD) and adaptive power transmission (APT) in the forward and backwa

Abstract:
Flexible Double Weight (FDW) Optical Code Division Multiple Access (OCDMA) Code is a newly developed code within DW family. Data format in communication system consist of two types which is Non-Return Zero (NRZ) and Return Zero (RZ) line code. Simulation analysis was carried out by using simulation tools Optisystem 15 to determine the performance of FDW system with different data formats. The analysis used different detection technique such as Single-Photodiode Detection (SPD) and Spectral Direct Detection (SDD). Based on the observation, NRZ has better performance than RZ as NRZ data transmis

Abstract:
Such as in any optical communication system, the light modulation is considered a main key to determine the performance (or the maximum) of the data rate that can be transmitted and over what the long distance can be applied. So, a choice of the modulation type in any optical link is more important and should base on measuring of the BER and the Q factor parameters. In that issue, we propose a comparative study as contribution between the principle or the schemes of the direct modulation (DM) and the external modulation (EM) respectively, which the chirp frequency modeling is described for the

Abstract:
AbstractThis study reports the efficient use of a direct laser modulated response measured with the return-to-zero coding scheme in optical transmission systems. The measured direct laser modulated response has a bit rate of 1.2 Gbps for an optical fiber cable of a transmission length of 10 km. The eye diagram analyzer is used to calculate the maximum quality factor and minimum bit error rate of the proposed model. The maximum quality factor is 531.2, and the minimum bit error rate tends to zero for the same optical fiber channel length compared with that of the previous model. The proposed mo

These modulation techniquesinclude On-Off keying and return to zero (RZ)/non–return to zero (NRZ) coding. The signal power level against time and frequency spectral variations are measured. The max. Q factor and min. bit error rate (BER) are estimated and clarified for each modulation code scheme by using an optisystem simulation model.
