11.6 Differences between single mode fibres and multimode fibres

Single Mode Fibres Multimode Fibres

1. In single mode fibres there is only one path for ray propagation.

1. In multimode fibres, large number of paths are available for light ray propagation.

2. Single mode step index fibres have less core diameter (<10 μm) and the difference between the refractive indices of core and cladding is very small.

2. Multimode step index fibres have larger core diameter (50 to 200 μm) and the difference between the refractive indices of core and cladding is large.

3. In single mode fibres, there is no dispersion.

3. There is signal distortion and dispersion takes place in multimode fibres.

4. Signal transmission capacity is less but ...
