Tests on power over fiber systems for safety high throughput co-transmission in analog radio over fiber fronthauls and space environments

Different tests on power over fiber (PoF) systems including high-throughput mobile fronthauls (MFH) and PoF cotransmission under safety conditions and feasible operation on picosatellite under LEO orbit are discussed. Including state of the art of monitoring techniques specifically designed for PoF systems using multicore fibers, relaying on Tilted Fiber Bragg Gratings, backscattering, and crosstalk. All of them without using active components. It is also shown some record experiments on a MFH where PoF, digital, and 5G NR Analog Radio over Fiber signals are simultaneously transmitted, achieving data rates close to 40 Gbps while delivering close to 0.7W of electrical power. Successful operation of a monitored PoF payload orbiting for close to one year is shown.
