With fiber optic, you get greater bandwidth as well as higher and more accurate data transmission. Performance of up to 10 Gbit/s and more is standard. Speeds depend on the type of cable used. Single-mode fiber offers the widest bandwidth and is commonly used for long distances. Multimode has a larger core. Larger cores mean, on the one hand, more data transfer and, on the other hand, more light refraction. This means that the signal deteriorates over longer distances, which is why multimode is used in the short-term distance range of up to approx. 550 m.

Fiber optics do not emit any signals and are particularly secure against tapping. Fiber optic networks make it possible for hardware and electronics to be positioned centrally in one place. This means that cable cabinets with systems that are distributed throughout the building are finally a thing of the past.

Fiber optic cable is light, thin and more durable than copper cable. In order to beat the speed of fiber optic with copper, a much higher quality cable must be used, which then has a larger outer diameter, is thicker and therefore weighs more. There are only minor differences in diameter or weight with fiber optic cables. Fiberglass has a small diameter and is easy to handle. Because of these advantages, fiber optic requires very little space in the cable duct.

The costs of fiber optic cables, components and hardware are continually falling. While it is more expensive than copper cable in the short term, it can be more cost effective in the long run due to cheaper maintenance and fewer outages. Furthermore, advances in field termination technology have significantly reduced the cost of fiber optic installations.
