We investigated pre, post-compensation and symmetrical or hybrid-compensation in the
presence of fiber nonlinearities with NRZ, RZ, Raised Cosine and Gaussian modulation …

In this paper, we investigate pre-, post-and symmetricaldispersion compensation methods
for 10/15Gb/s using different modulation formats like NRZ, RZ and RZ Super gaussian using …

The capacity of optical communication systems is rising exponentially in order to follow the
rapidly increasing demand for data traffic. Limitations due to dispersion and nonlinearities in …

Four wave mixing (FWM) in optical fiber is unwanted effect to an optical transmission system,
which can severely limit the wavelength division multiplexing (WDM) and lower the …

The main subject of study and analysis in this paper is the single-channel optical
communication network. A comparative analysis and evaluation of network performance is …

We analyze 100 Gbps ultra-high capacity WDM system for RZ, NRZ, CSRZ and Duobinary
modulation formats using pre, post and symmetrical compensation. Using symmetrical …

Research in optical communications is being constantly driven by requirements for higher
data rates and better spectral efficiency. On one hand, higher bit rates per channel involve …

In this paper, the effect of nonlinearity has been investigated with different techniques such
as non-return-to-zero (NRZ), return-to-zero (RZ), duo-binary return-to-zero (DRZ), and …

As is well known, chromatic dispersion (CD) and nonlinear effect such as self-phase
modulation (SPM), cross-phase-modulation (XPM), and four-wave-mixing (FWM), as well as …

Abstract Optical Fiber Communication is the rapidly evolving form of communication for long
haul applications. Due to its compact size, low losses and versatile application, it is …
