In this paper we investigate in OptSim software environment the system performance of intensity and phase modulation formats for different network scenarios and dense wavelength division multiplexing grids. OptSim employs the Time Domain Split Step method to implement the signal distribution equation in a fiber. We investigate intensity formats, such as Non Return to Zero, Return to Zero, Carrier-Suppressed Return to Zero and DuoBinary, and phase modulation formats like Differential Phase-Shift Keying and Differential Quadrature Phase-Shift Keying. The main goal is to compare these formats in terms of bit error rate, Q-factor, optical reach and grid limitations for transmission rates 10, 40 and 100 Gbps per channel and discuss the possibilities of increasing their spectral efficiency. We also focus on other advanced solutions such as the polarization division multiplexing combined with phase modulations, coherent detection and advanced digital signal processing which mainly benefits in spectral efficiency, optical signal to noise ratio and chromatic dispersion tolerances.

“…[2,3,4] The extra optics and detectors for this coherent detection become cost effective when used for 40 billion bits per second. [5] Fast low-power A/D samplers have been implemented in CMOS for a 40 Gb/s coherent product which will compensate up to 50,000 ps/nm of dispersion. We will discuss the performance measurements for this product and the prospects for using this method in a 100 Gb/s coherent product.…”

“…When the nonlinearity couples with other transmission impairments such as PMD, it can lead to complex dynamics. Thus PMD which is stochastic in nature and nonlinearity which is deterministic in occurrence should be addressed together for modelling high speed data transmission systems [9,10]. Nonlinear birefringence is another source of impairment in fiber communication [11].…”

To provide higher capacity optical fiber networks, a 107 Gb/s transmission system is simulated by using the combined features of polarization multiplexing (PM), quadrature phase shift keying (QPSK) and forward error correction (FEC). The lower tolerance to linear and nonlinear fiber impairments remains a major concern at a higher bit rate. To address the limitations set by the linear impairments, coherent detection of multilevel modulation formats with polarization division multiplexing appears as a promising solution by reducing the symbol rate to one-forth. Electronic dispersion compensation (EDC) and constant modulus algorithm (CMA) are used at the receiver for the linear dispersion compensation and forward error correction (FEC) respectively. Fiber spans each of 90 km are used in this simulation making the transmission length 1980 km. The bit rate of the modulating signals is kept at 26.75 Gb/s and the aggregate transmission rate of 107 Gb/s by utilizing the combined features of PM and QPSK. The power sharing of both the polarization components in the presence of polarization mode dispersion (PMD), fiber nonlinearities and random birefringence is a very important for the system design. In this paper, the PMD tolerance of the system at different transmitting powers with and without the presence of nonlinearities and birefringence are simulated and evaluated in terms of the bit error rate (BER). Transmitting power of 2.518 mW is found as the optimum value for single channel PM-QPSK systems at PMD 0.05 ps/sqrt(km).
