A fibre-optic system has no bandwidth limitations when transmitting signals in both uni-and bidirection simultaneously.
A fibre-optic cable carries only signal information of light at a frequency thousands of times higher than normal electrical signals.
Because it transmits only light signals, the fibre-optic cable can be made up of glass or plastic--totally non-conductive materials.
The fibre-optic cable can thus be employed in different and adverse environments, because the optical-only signal makes the system intrinsically safe.
As the need for more bandwidth increases rapidly, the efficient use of fibre-optic network backbone goes up dramatically as well.
A single, thin fibre-optic cable can replace miles of copper cables to serve all these media functions simultaneously, while IP network cable and Wi-Fi are limited by distance and strength in the field.
Fibre-optic systems are powerful enough to multiplex multiple signals--audio, video or data--into a single fibre-optic cable.
Nevertheless, reliable and stable fibre-optic systems have been running for decades.
