Performance Investigation of Hybrid Optical CDMA/ DWDM System Under the Influence of FWM
2023 IEEE 16th Malaysia International Conference on Communication (MICC)
Year: 2023 | Conference Paper |
The significance of nonlinear effects arising from inter- and intra-channel four-wave mixing (FWM) in a hybrid optical code-division multiple-access (OCDMA) and wavelength division multiplexing (WDM) network is thoroughly investigated in this research. The Electro-Optic Phase Modulator (EOPM) module, a crucial component introduced to the system to introduce a phase shift of an ideal value of 2π/3 ...Show More

Tawfig Eltaif;Khaled A. Alaghbari;Naif Alsowaidi;Belal A. Hamida
2021 26th IEEE Asia-Pacific Conference on Communications (APCC)
Year: 2021 | Conference Paper |
This paper demonstrating a successful photonics generation of 60GHz millimeter-wave by quadrupling a 15GHz RF signal with an unbalanced Mach-Zehnder modulator (UMZM). With a 4ps delay between the two arms of UMZM and by controlling the modulation index of UMZM, only two side bands can be generated along with the main carrier, which is suppressed by a band pass filter. Hence, a millimeter-wave of 6...Show More
Chromatic Dispersion Compensation for Offset- QAM/FBMC Based Coherent WDM Using Digital Filter
Khaled Alaghbari;Lim Heng Siong;Tawfig Eltaif;Naif Alsowaidi
2018 IEEE 7th International Conference on Photonics (ICP)
Year: 2018 | Conference Paper |
Cited by: Papers (2)
In this paper, the performance of chromatic dispersion compensation for offset quadrature amplitude modulation/filter bank multicarrier (OQAM/FBMC) based coherent WDM using digital filtering is evaluated. The digital filter is applied to equalize the chromatic dispersion at the data rate of 60 Gbit/s per user for a 16-channel WDM system. The performance of the digital filter is evaluated for diffe...Show More
Signal Quality Improvement in Optical PPM-CDMA Systems Based SIC Scheme
2018 IEEE 3rd Optoelectronics Global Conference (OGC)
Year: 2018 | Conference Paper |
Cited by: Papers (1)
Optical pulse position modulation-code division multiple access (PPM-CDMA) system with an interference rejection scheme is theoretically analyzed. Successive interference cancellation (SIC) scheme has the ability to suppress the overlapping between the users by subtracting the strongest one from the original received signals one by one until all users detected. Different optical codes have been us...Show More
Multi bidirectional passive optical network based on direct detection optical CDMA technique
Tawfig Eltaif;Mohamed Ahmed Alsaraj;N. Alsowaidi;M. R. Mokhtar
2014 IEEE 5th International Conference on Photonics (ICP)
Year: 2014 | Conference Paper |
Cited by: Papers (1)
In-band multi bidirectional passive optical network (MPON) based on optical code division multiple access technique was implemented. Up/downstream data carried by wavelengths in C-band with channel spacing 25/50GHz and all the data encoded by modified quadratic congruence code (MQC). The MPON network has been implemented to increase the system capacity by using the same code and same prime number....Show More
Bidirectional passive optical network based on optical CDMA technique
Tawfig Eltaif;Mohamed Ahmed Alsaraj;N. Alsowaidi;M. R. Mokhtar
2014 IEEE 5th International Conference on Photonics (ICP)
Year: 2014 | Conference Paper |
A 15 Km in-band bidirectional passive optical network based on optical code division multiple access (OCDMA) system was simulated, using direct detection method, which has been achieved by modulating the carrier wave with a modified quadratic congruence code sequence (MQC). This paper investigates the performance of in-band bidirectional OCDMA system in terms of data rate, channel spacing, transmi...Show More
