Simultaneous radio/pump/power-over-multi-core fiber transmission for optically powered radio units eliminating
Abstract:
We demonstrate simultaneous radio-/pump-/power-over-fiber transmission using a single multi-core fiber for downlink radio-over-fiber transmission. This scheme not only introduces a remotely pumped optical amplifier to eliminate electrical power amplifiers (PAs) in radio units (RUs) but also drives a high-power photodiode, which is the main component of the RU by power-over-fiber. Using this scheme, we achieved a 20-dB improvement in the RF output signal power using a remotely pumped optical amplifier without electrical PAs in the optically powered RU.
