The Terrestrial Backbone
Together with wireless and legacy copper, fiber optic communication links are the terrestrial backbone of our connected world, enabling everything from 5G smartphones and embedded WiFi, to our fast-growing dependence on AI, to the industry of things (IoT). These links range from “fiber to the home” to long-haul intercity trunk links and everything in between. And anywhere you find fiber, you will find Coherent components, devices, and instruments.
