Abstract

Higher spectral efficiency and data rate per channel are the most cost-effective approaches to meet the exponential demand of data traffic in optical fiber network communication system. In this paper, diverse modulation formats are analyzed for Dense Wavelength Division Multiplexed system at 100 Gbps * 16=1600 Gbps data rates. The performance analysis of proffered system for Non-Return to Zero, Return to Zero, Carrier- Suppressed Return to Zero and Duo binary RZ with duty cycle 0.5 to 0.7 ranges like modulation formats are considered to find optimum modulation format for a 100 Gbps bit rate per channel optical fiber transmission network system. The simulations are analyzed for different values of input power, length of fiber, nonlinear refractive index, nonlinear dispersion and nonlinear effective area for all above mentioned modulation formats with spacing 100 to 250 GHz. to evaluate the effect of modulation format Fiber Bragg Gratting, optical fiber amplifier and Dispersion Compensation Fiber dispersion compensation techniques are enacted on this proposed optical network system.

“…However, this multiplexing innovation is not without its drawbacks; it introduces nonlinear impairments that adversely affect the quality of transmission (QoT), including scattering and refractive index deviation distortions. Particularly troublesome among these nonlinear phenomena is four-wave mixing (FWM), a critical source of interchannel crosstalk and power penalties that impede the performance of long-distance and multi-channel OCNs [5].…”

“…[4]. These nonlinearities in the fiber can be classified into two, one due to scattering and the other due to refractive index [5]. Self-Phase Modulation, Cross-Phase Modulation, and FWM are nonlinearities caused by a change in the refractive index.…”

“…Also, NL attributes that occur as a result of scattering include Stimulated Brillouin Scattering and Stimulated Raman Scattering [2]. FWM occurs when four waves propagate concurrently inside a fibre [5].…”
