What is the Difference Between Multi-mode and Single-mode Fiber Optic Cabling
                     What is the Difference Between Multi-mode and 
Single-mode Fiber Optic Cabling?

• Fiber Optic cables are made of thin strands of glass or fiber. The fiber 
optic cables enable faster data transmission with a low attenuation rate.
• The fiber is coated with a protective plastic covering called the primary 
buffering coating that protects it from moisture and other damage. The 
cable is enclosed within an outer covering called a jacket.

Single-mode vs Multi-mode Fiber Optic Cable:
The difference between a single-mode and multi-mode fiber optic cable 
mainly lies in fiber core diameter, wavelength and light source, 
bandwidth, color sheath, distance, and cost.
Wavelength and Light source: The large core size requires low-cost 
light sources such as LEDs that work at wavelengths of 850nm and 
1300nm. Single-mode fiber uses laser or laser diodes to produce light 
injected into the cable.

Bandwidth: Multi-mode fiber optic cable bandwidth is limited while the 
single-mode fiber optic cable has unlimited bandwidth as it allows only 
one light mode to pass through at a time.

Color sheath: Single-mode fiber optic cable is covered with a yellow 
sheath and multi-mode fiber optic cable is covered with a blue sheath.
Core diameter: The higher core diameter of multi-mode fiber optic 
cable enables it to have higher light gathering ability and simplify 
connections. The attenuation of multi-mode fiber optic cable is higher 
because of its larger core diameter.
