In this study, we proposed the IoT sensor solution using a PoF module for the environmental monitoring a set of sub-modules in MMC-HVDC systems. PoF system was implemented as three laser modules (1 W, 976 nm) in the power supply area, multi-mode 62.5 /125-μm optical fibers, and three photovoltaic power converters with optical outputs up to 250 mW. The O/E conversion efficiency of the PPC was 28%, and the SIM with three PPCs has a maximum output of 0.75W. From the experimental results, to ensure operational reliability of the HVDC-MM C system, BLE sensor values of periodic environmental monitoring have been verified to be consistently received by a smart device.
