Crosstalk-Based Remote Monitoring Technique for Power over Fiber Signals in Spatial Division Multiplexing Links

Abstract

Power over Fiber (PoF) needs safety and resilience operation of the infrastructure. In this paper, we propose a new crosstalk-based remote monitoring technique of PoF signals in Spatial Division Multiplexing (SDM) optical networks with no consumption at the remote radio head (RRH). We monitor an 800 mW PoF delivery in a 250 m 7-core MCF co-propagating with a 5G-NR 256 QAM signal with EVM under 3.5% and a control channel. The PoF energy feeds a control board to reduce power consumption at RRH.
