Optical fiber is classified into different types (multimode or singlemode) depending on how it allows light to move. The type of fiber is closely related to the diameter of the core and the sheath.
Multimode fiber offers several advantages, mainly the lower cost of transmitters and receivers and the simplicity of coupling to them.
However, its relatively high attenuation (optical loss) and its low bandwidth limit the transmission to short distances.
Single-mode fiber benefits from its superior performance in terms of bandwidth and attenuation.
Due to the small size of its core, single mode fiber generally requires more expensive transmitters and alignment systems to achieve efficient coupling.

However, for high performance systems or those measuring more than a few kilometers, single mode fiber remains the best solution.
