5G Networks
Enable lower latency, greater
flexibility & efficiency
Installation of these networks are
in the very early stages
Installation will start in urban
hubs and will continue to expand
into suburban and rural areas
By 2025, only 14% of the world
will have 5G connections
Growth is expected over multi-
year period
5G technology will be a leading growth driver in fiber optic cable for several years
