    A new multicore fiber-optic monitoring system has the potential to enhance 5G. According to researchers at the Universidad Carlos III de Madrid (UC3M), in collaboration with the Universidad Politécnica de Valencia (UPV), such a system, which they have patented, could optimize energy consumption and preserve data transmission capacity. The team’s work could lead to a parallel system, in which they will continually monitor the node’s energy needs. And in obtaining a single optical signal, “the system can also monitor temperature changes in the fiber core, energy distribution using optical means at different network points, and the state of the communication channel used within the fiber.”
