“…DPA, one of the candidates for the distributed signal amplification in long-haul communication links, has been studied in recent research [18], [19]. Although once being regarded as detrimental in some previous research [20]- [23], DPA has several advantages over DRA in real applications including lower pump power, free from double Raleigh scattering (DRS), smaller pump power attenuation and idler generation [18]. Different from the discrete optical parametric amplifier (OPA) in the specially fabricated highly-nonlinear dispersion-shifted fiber (HNL-DSF) [24], [25], DPA adopts the widely available dispersion-shifted fiber (DSF) in which the transmission and amplification of the optical signal can be achieved at the same time [18].…”

An optically powered communication system with distributed amplification is demonstrated using either distributed parametric amplification (DPA) or distributed Raman amplification (DRA) within the dispersion-shifted fiber (DSF) and single-mode fiber (SMF). At the fiber output the residual pump after the distributed amplification is recycled to power the receiver component. Our scheme is also a potential candidate for the 'last mile' transmission. Based on our scheme, 4 channels of 10 Gb/s WDM signals are used to obtain practical performance evaluation. In the presence of 10-dB gain for signals, the power penalties of 1 35-dB at the BER of 10 9 are achieved for DPA in DSF, and as the comparing counterpart of DPA, counter-pumping DRA induce approximately the same level of power penalty (1 55-dB) in DSF and 1 96-dB in SMF. Co-pumping DRA are also tested in both kind of fibers. Finally, the energy-efficiency issue for different pumping schemes is analyzed.

INTRODUCTION O PTICALLY supplied energy has been well known for a long time, from using solar radiation as power source for satellites in space to the more down-to-earth example of solar battery for household equipments. While in the context of an optically powered communication system, both the optical signal and the power are transmitted in the optical fiber. The advantages of using optical power over traditional electrical means are obvious, such as total immunity to electromagnetic interference, electromagnetic radiation free operation and high electrical resistance which are always concerns in electrical communication systems. And these characteristics also make optical power more environment-friendly than its electrical counterpart. Running through the short history of optically powered fiber system, Deloach et al. made the first description of an optically powered sound alerter in 1978 [1], soon followed by an optically powered speech communication system [2]. Later in 1989, Kirkham and Johnston [3] reviewed the optically powered devices in the past and presented an optically powered data link. In

“…In fact, to the best of our knowledge, possible asymmetry in transmission performance degradation has neither be discussed nor clarified quantitatively: As is already reported in Ref. [3], the spectrum of MI gain becomes wider as the value of dispersion becomes smaller in anomalous dispersion region, while there is no MI gain in normal dispersion region [5]. This stimulates our interest how the signal degradation due to MI changes when the signal wavelength changes from anomalous dispersion to normal dispersion or vise versa.…”

“…If the signal wavelength is set at or near zero dispersion region of transmission fiber in long-haul optical amplifier repeatered system, severe SNR degradation is known to be induced due to parametric amplification (MI gain) of ASE noise on each side of the signal [2,3]. In order to mitigate the degradation, non-zero dispersion shifted fiber, dispersion management fiber, and etc.…”

Abstract:In order to explore possible asymmetry of nonlinear degradation near zero dispersion, nonlinear propagation of single-channel 10Gbps signal at and near zero dispersion wavelength of dispersion-shifted optical fiber (DSF) is comprehensively investigated in terms of signal power and wavelength as well as transmission distance. Inherent nonlinear degradation near zero dispersion appears to be symmetric in terms of wavelength despite that Modulation Instability (MI) gain should vanish in normal dispersion with deviation from zero dispersion.

“…This may lead to broadening of the signal spectrum, signal distortion, and enhanced noise from amplified spontaneous emission (ASE) of optical amplifiers [6][7][8][9][10], especially in a chain of optically amplified fiber sections [11]. The effect of MI may be reduced by proper dispersion management [10] and possible optical or electrical dispersion compensation [12,13]. However, there is an uncertainty/variation in the dispersion value of commercially available dispersion-shifted fibers of about 3 ps/km/nm [14].…”
