“…The results also revealed that minimum crosstalk was induced in backward pumped DRA among the three pumping schemes i.e forward, backward and bi-directional. Results assumed importance for minimizing deleterious XPM and SPM effects in optical communication system (Anamika, 2013).…”

A nonlinear Schrodinger equation has been solved in order to establish the nonlinear optical self phase modulation (SPM) actual magnitude in fiber (within optical domain), the SPM magnitude was simulated at 40 GHz in relation to normalized time and actual distance within the fiber. When the SPM signal comes out of the fiber and enters a pre-designed transimpedance amplifier (TIA) (electronic domain), and according to simulation, the SPM signal corresponds to an input noise spectral density of 320.3 pA 2 /Hz (electronic domain) that enters the TIA. A significant reduction in S 21 scattering parameter, nonlinear optical power and nonlinear noise figure were registered when the 320.3 pA 2 /Hz is entered at the TIA input. That effectively means a reduction in SPM value using the TIA at 40 GHz. A Microwave Office software was used for simulation.

“…It is also observed that quality factor reduces for lesser channel spacing [13]. More recently, the performances of a WDM system with distributed Raman amplifier are investigated with SPM and XPM effect [14] by simulation. The analytical and simulated works have been reported in Ref.…”

Analysis is carried out for a single span wavelength division multiplexing (WDM) transmission system with distributed Raman amplification to find the effect of amplifier induced crosstalk on the bit error rate (BER) with different system parameters. The results are evaluated in terms of crosstalk power induced in a WDM channel due to Raman amplification, optical signal to crosstalk ratio (OSCR) and BER at any distance for different pump power and number of WDM channels. The results show that the WDM system suffers power penalty due to crosstalk which is significant at higher pump power, higher channel separation and number of WDM channel. It is noticed that at a BER 10 −9 , the power penalty is 8.7 dB and 10.5 dB for the length of 180 km and number of WDM channel N = 32 and 64 respectively when the pump power is 20 mW and is higher at high pump power. Analytical results are validated by simulation.

“…Examples of low complexity modulation techniques are OOK (On-off shift keying), duobinary, DPSK and DQPSK [2]. DPSK modulation format is an excellent option, since it offers better tolerance to chromatic dispersion and fiber nonlinearities than OOK [3], [4], increasing the spectral efficiency and improving the coverage and capacity of the access network [5].…”

En este artículo se analiza el impacto del ancho de línea en el desempeño de una red de acceso óptica en la que se emplea el formato de modulación DPSK. Se demostró, mediante simulaciones, el efecto del ancho de línea sobre la BER (Bit Error Rate). Se analizó el desempeño para diferentes velocidades de transmisión y valores de dispersión en la fibra óptica. DPSK es un formato simple y de menor costo comparado con el uso de detección coherente, DPSK. Se encontró que puede emplearse un mayor ancho de línea al incrementar la tasa de bits, lo que significa un menor costo de implementación. Se propone a DPSK como el siguiente paso en la actualización de la red de acceso actual que emplea modulación en intensidad.
