Front 8

Describe microbending...

Back 8

Small bending in the cladding/core can cause scattering or microreflections.

Front 9

Describe Macrobending...

Back 9

Large bends in the cable itself. B/c long wavelengths can travel more in the cladding and is thus more loosely guided than multi-mode, single-mode is more sensitive to macrobending.
