In a single mode fibreoptic cable
- several light wave modes can propagate simultaneously through the cable.
- the diameter of the cable is dependent on the wavelength of the light used.
- the distortion of the signal is determined by the total length of cable used.
Explanation from PART66Online
Single-mode fibre has a core only a few wavelengths across, so its core diameter is tied to the wavelength of the light used-that small size permits just one propagation mode. Allowing several modes to propagate simultaneously describes multimode fibre, not single-mode.
