“…Therefore, high bandwidth based devices will play a major role in the next generation networks. Erbium-doped fiber amplifier (EDFA) has been extremely compatible to both low and high bandwidth communication networks [1]. In order to cope with the bandwidth demand, new EDFAs has been proposed to provide high gain and to fully utilize the redundant fiber bandwidth [2,3].…”

Abstract:We propose a new pumping method for optical fiber amplifiers at 1480 nm and 980 nm that is able to provide high gain and low noise-figure. The gain and noise figure obtained were 38.3 dB and 5.5 dB with an improvement of 3.8 dB and 1.4 dB, respectively, at 1550 nm, for −30 dBm input power when compared to its counterpumped design. This design also delivers higher gain and lower noise figure when compared to the common bi-directional dual-pumped designs. A power conversion efficiency of 44.5% was achieved in this design.

“…The OOK format using either RZ or NRZ modulation is still used by many of these OTDM-WDM systems [2]. Quite often in practice, an optical filter is placed after OTDM demultiplexing 458 C. C. Hiew et al [1,4].…”

“…The combination of OTDM with WDM can reduce the number of WDM channels used in high capacity transmission by increasing the bit rate per WDM channel [1][2][3]. The OOK format using either RZ or NRZ modulation is still used by many of these OTDM-WDM systems [2].…”

The impact of a post-OTDM-demultiplexing optical filter on the performance of dense on-off keying (OOK) optical time division multiplexing (OTDM)-wavelength division multiplexing (WDM) systems was studied. For return-to-zero (RZ) modulation, it was found that the additional filter working in a double-tier filter configuration did not offer any significant improvements to performance when the signal pulse width is optimized. Improvements generally increase only when the signal pulse width deviates from its optimal value and only for low spectral densities. For ideal non-return-to-zero (NRZ) modulation, however, significant improvements of around 1 dB are obtained using the double-tier configuration over a large range of spectral densities.

“…As a consequence, we focus our analysis on RZ systems, and we compare two of the compensation methods presented in literature: periodic compensation and all-at-the-end compensation. Periodic compensation has already been investigated [1]- [3], with the conclusion that the system's best performances can be achieved introducing a small prechirp at the beginning of the link. On the other side, the all-at-the-end compensation scheme has been introduced quite recently [4], [5] and is based on the transmission of very short RZ pulses that are rapidly dispersed and allowed to reduce the effects of self-phase modulation (SPM).…”

“…There are a few papers [1]- [4] that report numerical and experimental results on this kind of fibers, but there are still a number of open issues-not only on which is the best dispersion compensation method to be used, but also on the tolerances acceptable in these systems and on their behavior with respect to several nonlinear effects.…”

Abstract-In the literature, two system solutions have been proposed to overcome high dispersion problems typical of G.652 fibers at high bit rates (40 Gb/s): they are periodic and all-at-the-end dispersion compensation. We carry out an exhaustive comparison between the two methods that, up to this moment, have been studied separately. In the first part, we introduce a simplified model on strong dispersion management (DM) with intrachannel four-waves mixing (IFWM) and intrachannel cross-phase modulation (IXPM). We then carry out extensive numerical simulations of a complete system in order to verify the results as a function of the input average power and of the input pulsewidth. Finally, we tackle a typical system aspect, i.e., the influence of nonlinear effects on dispersion compensating fibers (DCFs).
