Types of optical fibres

Optical fibres come in two types: Single-mode fibres and Multi-mode fibres.


Single-mode fibres have small cores (about 9 microns in diameter) and transmit infrared laser light.


Multi-mode fibres have larger cores (62.5 microns in diameter) and transmit infrared light from LEDs.


Some optical fibres can be made from plastic. These fibres have a large core (1 mm diameter) and transmit visible red light from LEDs.
