Fiber optic cable (FOC)
What is called optical fiber cable (FOC)?
FOC are optical fibers. Fiber optics transmit data in the form of light signals at high speeds over long distances.They can be made of plastic or glass, the latter is called fiberglass. Optical fibers are therefore electrically non-conductive. The optical fibers are very flexible, but they can break if they are bent too much. For this reason, professional laying is essential. The optical fibers are covered with a plastic layer that protects them.
The optical fibers can transmit light signals of certain wavelengths. Fiber optic speeds depend on the type of cable used. A distinction must be made here between single mode and multimode. The differences lie mainly in the fiber core diameter, the wavelength, the light source and the bandwidth.
Singlemode
Singlemode has a very small core (9µm) that only allows one type of light. This means that the attenuation is very low and offers the advantage of using this optical fiber over longer distances.
