We demonstrate improved performance of parametric amplifier cascaded with Raman amplifier for gain of 54.79 dB. We report amplification of L-band using 100 × 10 Gbps Dense Wavelength Division Multiplexed (DWDM) system with 25 GHz channel spacing. The gain achieved is the highest reported so far with gain flatness of 3.38 dB without using any gain flattening technique. Hybrid modulated parametric pump is used for suppressing four-wave mixing (FWM) around pump region, resulting in improvement of gain flatness by 2.42 dB. The peak to peak variation of gain is achieved less than 1.6 dB. DWDM system with 16-channel, 25 GHz spaced system has been analyzed thoroughly with hybrid modulated parametric pump amplified Raman-FOPA amplifier for gain flatness and improved performance in terms of BER and Q-factor.

AbstractIn this paper, we investigate the effect of channel spacing and chromatic dispersion on four wave mixing in WDM system. Dominating effect of four wave mixing is minimizing at maximum value of dispersion and channel spacing. Power of FWM, Q-factor, bit error rate and output spectrum is used to measure the performance of system.

Simulation Results

The integration of wireless and optical networks increases the capacity and mobility as well as decreases costs in the access networks. However, there are nonlinearity and obstacles preventing them from being perfect media. A serious issue for WDM systems is the presence of resonant four wave mixing (FWM) terms, as a result of interactions between different channels. FWM presents a major source of non-linear cross talk since they often fall near or on top of the desired signals. So the best solution is to avoid the FWM generation from early design stages. The effect of four wave mixing (FWM) as one of the influential factors in the WDM for RoF has been studied here using Optisystem. The investigation of FWM effect with different number of channels at various channel spacing has also been done. The simulation results reveal that the less number of users at input cause less FWM but in today’s technology, it is important for the circuit to handle WDM.

Nonlinear Impairments

The main challenge faced in today's telecommunication is the ever increasing demand for bandwidth and data rates. The desire to expand the capacity of fiber optic communication to accommodate this demand accelerated the development of high capacity Dense Wavelength Division Multiplexing (DWDM) transmission equipment. However, nonlinear impairments are the fundamental limiting mechanisms to the amount of data that can be transmitted in DWDM. In DWDM, Four Wave Mixing is the most critical of nonlinear effects in fibre optics communication. This effect limits the DWDM’s channel capacity. There are numerous researches on nonlinear impairments that show the intricacy of FWM phenomena in DWDM system. This article present review of the several measures which have been carried out by researchers to overcome nonlinear effects in DWDM. Such measures include Modulation Formats, Channel Spacing, Channel Shuffling Algorithm and Electro-Optic Phase Modulation. The review provides insight into the methods, parameters and approaches used by other researchers. This will pave way for can thus lead to significant improvement in the design of DWDM system.
