“…In Fig. 3a SEE is estimated in a point to point link with two connectors with 0.4dB loss/each and a 100% coupling efficiency from HPLD to the optical fiber as in [7]. The specific parameters are the operating wavelength, the PV efficiency provided in Table II and the related silica optical fiber attenuation in dB/Km.…”

“…On the other hand, the use of this technology has diversified into multiple fields such as optically powered remote antenna units [4], [5], [7], [8] or controlled beam steering for Radio over Fiber Networks [9], remote sensor feeding [10] in hazardous environments with high electromagnetic interference (EMI) for measuring the gas density of extra high-voltage substation gas-insulated switchgear [11], for partial discharges monitoring [12] or for current monitoring in transmission lines [13]. Other PoF applications are reviewed in [14], but those specifically within the security sector include the remote feeding of different type of subscribers including a video surveillance system [15].…”

Potential niches for Power-over-Fiber (PoF) technique can be found in hazardous areas that require controlling unauthorized access to risk areas and integration of multiple sensors, in scenarios avoiding electromagnetic interference, and the presence of ignition factors. This paper develops a PoF system that provides galvanic isolation between two ends of a fiber for remotely powering a proximity sensor as a proof of concept of the proposed technology. We analyze scalability issues for remotely powering multiple sensors in a specific application for hazardous environment. The maximum number of remote sensors that can be optically powered and the limiting factors are also studied; considering different types of multimode optical fibers, span lengths and wavelengths. We finally address the fiber mode field diameter effect as a factor that limits the maximum power to be injected into the fiber. This analysis shows the advantages of using Step-index versus Graded-index fibers.

“…Any PoF system requires wavelength matching between HPLD, PV efficiency and optical fiber attenuation. Typically, for silica fibers and link lengths below 1 Km, PV efficiency is the dominant factor whereas for longer distances, optical fiber attenuation is dominant and 1480nm provides better overall efficiencies 2,3 . Other design aspects are the temperature influence on HPLD and PV performance, efficiency of optical coupling, maximum power allowed by optical fiber and passive devices, the required electronics, heatsink, and electrical output power.…”

This paper introduces a novel concept for Remote Radio Head (RRH) powering: PoF pooling, and its application for Multi-Core Fiber (MCF) enabled by SDN. Simulations using stochastic geometry prove the benefits of this approach in a phantom cell scenario. PoF pooling concept As the power requirements of small-cell RHH of next generation cellular systems become lighter thanks to technologies like Radio-over-Fiber (RoF), the prospects to make possible cellular networks remotely fed by optical fiber are becoming a reality. One of the challenges for PoFsupported 5G systems is to make them scalable to hundreds or thousands of small cells by using a single power supply location, either at the Central Office (CO) or the closest Macro-cell Base Station (MBS). Even though local power units on each base station are no longer needed, achieving high savings, the amount of costly HPLDs (High-Power Laser Diodes) required to feed all the cells may hamper many initiatives until PoF becomes mainstream. Furthermore, a static allocation of fibers for remote powering may hinder flexible resource allocation in the access network. In this paper we present the concept of PoF pooling and PoF switching to address this problem, allowing a selective use of a fiber core for power, data transfer or both. The concept of PoF pooling is sketched in Fig. 1. The infrastructure is composed of multiple cell sites connected to a CO through a hy-ODN Cell site (CS) A

“…the delivery of power through an optical fiber, is now seen as a realistic option not only to feed some reconfigurable elements in optical access network [1] but also to optically powering controlled beam steering in radio-over-fiber (RoF) networks [2] and remote antenna units (RAU) in picocellular access network architectures [3]. The reduction of the cell size of RAUs, boosted to support the higher data rate demands of radiofrequency signals targeted by the upcoming 5G technology, has opened up new application niches for this PoF technology [4][5]; where power consumption demands are foreseen to be dramatically reduced. This includes novel concepts as PoF pooling [6] which can make PoF scalable to outdoor small cell deployments.…”

We explore the potential of optical power delivery in multicores fibers, either using individual cores only for power or to share both data and power signals into the same core. A comparison between both scenarios in terms of power levels for different link lengths and number of elements required is provided. We measure the impact of high power-over-fiber signals at 1480nm on the data transmission quality in a 4-core multicore fiber. Both dedicated-and shared-core scenarios are evaluated showing both negligible data traffic quality performance changes.
