Fibre broadband is more weatherproof than copper broadband. "Electronic Communications Networks (ECN) operators have noted that newly built fixed access ECNs that rely on fibre are more resilient than legacy copper ECNs. This is because fibre-based infrastructure is more resilient to water ingress and lightning strikes relative to copper. Fibre overhead lines are exposed to strong winds, however, fibre cables are lighter than the same diameter copper cable. This implies that after copper cable is retired the weight loading on overhead routes and the corresponding damage risks will be reduced which will make the overhead lines less vulnerable to wind damage."
