“…To develop our prototype, we have chosen a 10 km long SMF because of its low attenuation in the range of telecommunication wavelengths. The photovoltaic power converter is built of InGaAs/InP and its optical/electrical (O/E) conversion efficiency is approximately −6 dB around 1500 nm [5]. The continuous high power laser source (HPS) is a Raman fibered laser and is able to provide 10 W (40 dBm) around 1480 nm.…”

“…Usual applications using power-over-fiber are designed to transmit relatively low optical power supplies (several milliwatts) over single-mode optical fiber (SMF) links up to 10 km long [4]. To our knowledge, only one application has been reported of providing an optical power supply of 2 W but only over 2 km [5]. In our system, we need to provide several hundreds of electrical milliwatts to the instrument (sensor and interface).…”

We describe a quasi-all-optical extension dedicated to simplifying the deployment of submarine cabled observatories. Based on power-over-fiber technologies, high power supply and data are both transmitted in one optical fiber of a few kilometers in length. We study the Raman amplification on the down-and upstream data in the static regime with the high optical power varying from 100 mW to 4 W over a 10 km long single-mode optical fiber. We focus on the data optical budget and signal to noise ratio dependence with respect to the high optical power value and the data optical wavelength. We also present the transmission quality in the dynamic regime of this quasi-all-optical extension.

“…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].…”

“…Owe to this important characteristics of DPA, the residual parametric pump can provide power for the remote subscriber of the communication system. Based on the previous work on DPA [18], [19], the emphasis of our experiment is on: (1) the WDM issue; (2) the comparison between DPA and DRA; (3) the detailed energy-efficiency analysis of different distributed amplification schemes.…”

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

“…The multilongitudinal mode emission also takes up a large wavelength band, which causes difficulties multiplexing with data. A recent solution employed a single-mode laser that was modulated externally and amplified optically [14,15]. The method used external modulators together with highspeed driving electronics to broaden Δν p .…”

Broadband optical chaos for stimulated Brillouin scattering suppression in power over fiber

Broadband chaos generated in an optically injected semiconductor laser is applied for power-over-fiber transmission. By varying the injection power, period-one oscillation, period-two oscillation, and chaotic oscillation are observed in the injected slave laser, indicating a period-doubling route to chaos. Compared to the free-running output of the laser, its chaotic output has a drastically increased signal bandwidth, which leads to a 19 dB increase of the stimulated Brillouin scattering threshold. Using a chaos of 5:2 GHz bandwidth, a maximum optical power of 27 dBm is obtained after 20 km transmission over fiber, which is applicable to optically powering some advanced communication networks. The approach uses the inherent nonlinear laser dynamics, which requires no modulation electronics or microwave signal sources.
