How does the claddibg with lower refractive index reduce the light loss from the core?

Thank you.

claddibg with lower refractive index reduce the light loss from the core?

i think its a detail technology of cabling of optical fibres with using proper refractive index medium so that losses while bending the cable can be minimized .
i personally am not an expert but you can consult the following for details

Bending an optical fiber can cause loss, and single-mode optical fibers can ... It has a lower refractive index than the core or the cladding. ... light from escaping the core of the optical fiber when it is bent reducing the amount of attenuation.
