Fiber optic cables are common in almost every network. Their ability to carry large amounts of data at the highest speeds makes them ideal for the backbones of most networks. They connect everything from computers and laptops, to cities and countries. Without them, we’d be stuck with copper cables, radio and microwave links, and satellite uplinks—none of which are as versatile, fast, or cheap as fiber cables.

The advantages of fiber optic cable are numerous: power, reach, speed, durability, reliability and security. These advantages mean they enable the transition to fully digitalized cities, businesses and homes, creating a more sustainable and circular way of life. Here’s a look at fiber optic advantages in detail:

Resilience. Fiber optic cables are resistant to temperature shifts and severe weather conditions. They are lighter, thinner and sturdier than copper cables, and are less likely to break or get damaged. They are also more secure, because it is very difficult to intercept their transmissions. They are not affected by electromagnetic interference, which can disturb signals. Fiber optic cables can carry signals as far as 40 kilometers without signal degradation, while the maximum distance for copper cables is just under one kilometer. Fiber optic networks have low latency. In other words, they are fast. This rapid data transfer makes it possible to implement self-drive AI systems for cars or drones, telemedicine, national security, or to manage safety on building sites and work areas, to name a few. Better streaming and gaming. The higher data capacity of fiber optic networks means that they don’t get overloaded as easily as copper cable networks, so it’sfaster to download and stream your favorite films. And the stability of fiber means there are no “hiccups” to interrupt gaming at the wrong moment. Smart homes. Fiber optic networks are robust enough to support your home office, stream your favorite films, and connect to Internet of Things (IoT) devices like thermostats, alarms and home appliances.
