Fixed scattering section length with variable scattering section dispersion based optical fibers for polarization mode dispersion penalties

This work presents the gallium arsenide (GaAs) electro-optic absorption (EA) modulators performance evaluation compared to the previous models with SiGe EA modulators under high-temperature variations. The average switching speed is studied and analyzed for both EAs. The consumed energy or power per bit is taken into account for both modulators. The modulation depth and transmission coefficient are studied for both previous and proposed EAs with 250 Gb/s at room temperature. The technical performance parameters are also analyzed such as insertion loss, modulation depth, output power, contrast ratio, transmission coefficient, and power length product for both previous and proposed EAs under high-temperature variations. The study assured that to get the optimum GaAs EAs performance efficiency, the modulator length and the thickness should be values of 50 and 5 mm, respectively at room temperature.

This work outlined the integrated role between vertical cavity surface emitting laser diodes with Gaussian pulse generators and Ideal erbium doped fiber amplifier (EDFA) for the self-phase modulation instability management, as well as the signal/NP level (Power level [PL]) with the spectral frequency is simulated after wavelength division multiplexing (WDM) fiber at length of 10 km based third order Gaussian pulse generators. The light power variations against temperature after WDM fiber is also studied at length of 10 km based various order Gaussian pulse generators. Electrical received power (ERP) variations against temperature is clarified after avalanche photo diode (APD) photodetectors based various order Gaussian pulse generators. The study emphasis the bad effects of the increase of the temperature, and higher Gaussian pulse generators order on the signal power levels.

Optical fiber coarse wavelength division multiplexing (CWDM) with erbium-doped fiber inline-amplifiers for the linear polarization geometrical model is studied in this paper for fiber system optimization by using the Optisystem simulation software. Signal gain (SG), noise figure (NF), and signal/noise are measured against CWDM optical fiber variations. The erbium-doped fiber amplifier (EDFA) is based on the Giles model which solves the steady-state rate equations for SG and signal absorption parameters with the cross-section area of the amplifier itself. The signal is optimized at EDFA length of 6 m, 10 Gb/s data rates (DRs) transmission and 10 km CWDM fiber optic length (FOL). Max. Q factor is degraded and min. BER is upgraded with both CWDM optical FLs and higher DRs transmission increase.
