Single-Mode #Fibre-Optic Cable composed of four layers, from outer layer to inner layer: the jacket (900 µm), buffer (250 µm), cladding (125 µm), and core (8-9 µm). Due to its small core diameter (compare to Multimode Fibre-Optic Cable), it allows only one mode light propagation. However, in compensation, the light pulse could travel in long distance, and it can carry high bandwidth without worrying too much about distortion.

Multimode Fibre-Optic Cable
Multimode #Fibre-Optic Cable is composed of three layers, from outer layer to inner layer: the coating that protects the inner layers, the cladding that keeps light in the core, and the silica or plastic core that carriers the signal. The light could propagate in the form of multiple wavelengths where each could take a slightly different path due to its large core diameter (typically 50-100 µm, larger than Single-Mode Fibre-Optic Cable). However, its covering distance is much shorter, less than 2 km, due to possible dispersion.

Fibre-Optic Cable
Fibre-Optic Cable or Optical-Fibre Cable is a medium to carry data transmission in the form of light pulses, which is made by a flexible, transparent fibre made from drawing glass or plastic. It is usually used for #Metropolitan Area Network (MAN) connection. Basically, there are two types of Fibre-Optic Cable: multimode# and single-mode.
