TLDR
In this article, an appropriate pre-chirping through phase modulation can improve the nonlinear characteristics and maximum transmission length in NRZ based transmission systems over standard single mode fiber (SSMF).Abstract:
Chirped NRZ (nCRZ) modulation format has been presented for single channel and WDM 40 Gbit/s transmission. The transmission properties of cNRZ are compared with conventional NRZ and RZ signals and analysed by means of numerical simulations. It was shown that an appropriate pre-chirping through phase modulation can improve the nonlinear characteristics and maximum transmission length in NRZ based transmission systems over standard single mode fiber (SSMF). The results confirmed that the use of a cNRZ form reduces the self phase modulation-group velocity dispersion (SPM-GVD) impairments in SSMF compared to NRZ and RZ signal forms.read more

RZ/CSRZ-DPSK and chirped NRZ signal generation using a single-stage dual-electrode Mach-Zehnder modulator
TL;DR: In this paper, a single-stage dual-electrode Mach-Zehnder modulator (DE-MZM) was proposed for return-to-zero (RZ) differential phase-shift keyed (DPSK), carrier-suppressed (CS) RZ DPSK, and chirped non-return-tozero (CNRZ) signal generation.

Chirp Control of an Electroabsorption Modulator to be used for Regeneration and Wavelength Conversion at 40 Gbit/s in All-Optical Networking
TL;DR: An analytical model for the chirP performance of an EAM capable of optical regeneration and simultaneous wavelength conversion operating at 40 Gbit/s is derived and an optimum range of bias voltage is determined to ensure reduced chirp operation when a two-tone signal is applied to the EAM.

TL;DR: In this paper, the authors compared non-return-to-zero (NRZ) and return-tozero (RZ) signal transmission in dispersion-managed high-speed time-division multiplexed (TDM) systems operating at 1.55 /spl mu/m over the already installed standard-fiber network.

Reduced model to describe SPM-limited fiber transmission in dispersion-managed lightwave systems
TL;DR: A reduced model to describe self-phase modulation-limited fiber transmission in dispersion-managed lightwave systems is presented and by introducing a new figure of merit, the maximum transmission distance versus optical power can be determined without any numerical simulation.

A 40-Gb/s/ch WDM transmission with SPM/XPM suppression through prechirping and dispersion management
TL;DR: In this paper, the authors proposed to combine prechirping with dispersion management scheme in such a way as to suppress the power penalty induced by self-phase modulation (SPM) and XPM in 40-Gb/s per channel WDM transmission systems with long-amplifier spacing.
