As 100-Gb/s coherent systems based on polarization-division multiplexed quadrature phase
shift keying (PDM-QPSK), with aggregate wavelength-division multiplexed (WDM) capacities …

Publisher Summary This chapter provides a taxonomy of optical modulation formats along
with experimental techniques for realizing them. High-speed optical transmission systems …

Raman amplification has enabled dramatic increases in the reach and capacity of lightwave
systems. This tutorial explains why, starting with the fundamental properties of gain from …

We demonstrate a 120 Gb/s coherent polarization-multiplexed quadrature-phase-shift-keyed
transceiver with soft-decision forward-error-correction (SD-FEC) coding based on Turbo …

We analyze the equivalent optical noise figure (NF) performances and double Rayleigh-
scattering-induced noise characteristics of distributed Raman amplifiers based on higher …

Lightwave communication systems carry information that is encoded onto the intensity,
phase, or polarization of light from one point to another along an optical path. When …

Telecommunication carriers have to estimate the Raman parameters of the fibers installed
on their optical transport networks in order to facilitate the design of the next generation of …

Dispersion compensating modules (DCM) are key components in long distance and high-
speed fiber-optic transmission systems. However, many types of DCMs exhibit multipath …

The impact of multipath interference (MPI) in all-Raman multispan dispersion-compensated
links operating at 42.67 Gb/s was studied. D+/D-and D+/D-/D+ compensation schemes were …

Amplificadores a fibra dopada com érbio de dupla passagem (DP-EDFA) contendo fibras
compensadoras de dispersão (DCF) são estudados nesta tese. Os DP-EDFAs são uma …
