TL;DR: In this article, the potential of electronic dispersion compensation (EDC) in amplified multispan 111-Gb/s wavelength division multiplexed systems based on polarization-multiplexed quadrature phase-shift keying modulation with coherent detection was investigated.
Abstract: We carried out an extensive simulative analysis to investigate in depth the potential of electronic dispersion compensation (EDC) in amplified multispan 111-Gb/s wavelength- division-multiplexed systems based on polarization-multiplexed quadrature phase-shift keying modulation with coherent detection, also in the presence of substantial fiber nonlinearity. For typical single-mode and nonzero dispersion-shifted fibers, our results show that the use of inline optical dispersion management is always suboptimal versus using EDC at the receiver.

TL;DR: In this article, an 850-fs pulse train at 40 GHz was directly generated from a regeneratively FM mode-locked fiber laser using the soliton effect to generate a short pulse and suppress the supermode noise.
Abstract: An 850-fs pulse train at 40 GHz was directly generated from a regeneratively FM mode-locked fiber laser. The soliton effect was used to generate a short pulse and to suppress the supermode noise. The laser was locked to an external signal by a phase-locked loop (PLL) technique and the wavelength was tunable between 1540 and 1555 mn.

TL;DR: In this article, a tunable liquid-crystal Fabry-Perot interferometer filter with a Peltier controller has been proposed for wavelength-division multiplexing communication systems.
Abstract: We explain how to obtain the bandwidth and tunable range required for wavelength-division multiplexing communication systems and how to design tunable liquid-crystal Fabry-Perot interferometer filters. The main factors determining the performance are liquid-crystal loss, mirror loss, surface roughness, and parallelism, as well as mirror reflectivity and cavity gap. Experimental results closely agree with the designed performance. Temperature dependence, response time, acceptable input power, and reliability are investigated. Pigtailed polarization-independent filter modules with a Peltier controller are made and are shown to have low polarization dependence ( >

TL;DR: Enhanced upstream transmission at 10 Gb/s using a low-bandwidth reflective semiconductor optical amplifier is demonstrated and discussed for extended wavelength- division-multiplexing passive-optical-network applications.
Abstract: Enhanced upstream transmission at 10 Gb/s using a low-bandwidth reflective semiconductor optical amplifier is demonstrated and discussed for extended wavelength- division-multiplexing passive-optical-network applications. Significant improvement in terms of transmission performance is achieved with the use of electronic equalization and optimum filter offset placed at the receiver (optical line terminal) end only. According to filtering detuning, an analytical discussion is presented, explaining the bandwidth enhancement achieved with the proposed technique. The experimental studies consider the benefits of the electronic feed-forward and decision-feedback equalization as well as the required optimum offset optical filtering characteristics.
