“…When we take the "last mile" transmission into account, optically powered fiber link could easily find its position. Unlike the traditional "last mile" transmission, i.e., twisted pairs or electrical cable connections, optical fiber has the advantages of low attenuation, large transmission bandwidth, and high signal-tonoise ratio (SNR), not to mention the economical factor in the long-run of maintenance and repair [6], [7]. Another possible choice for the "last mile" transmission is free space optics (FSO) or optical wireless links [8], [9].…”

We report, for the first time to our knowledge, an optically powered wavelength-division-multiplexing (WDM) communication system with distributed parametric amplification in the dispersion-shifted fiber. The parametric pump for the amplification of WDM signals also acts as the power supply for the receiver component. The proposed scheme is also a potential candidate for the "last mile" transmission. Successful musical signal transmission has been demonstrated. Additionally, four channels of 10-Gb/s WDM signals are used to get more precise performance evaluation of the system. The power penalties of less than or equal to 1.35 dB at a bit-error rate of 10 9 are achieved for all WDM channels in the presence of 10-dB parametric gain.

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
