Experiments on Shared- and Dedicated- Power over Fiber Scenarios in Multi-core Fibers

The paper explores 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.
