Which challenge directly escalates as the refractive index contrast between core and cladding decreases in a fiber optic cable?

💡 Explanation

Reducing refractive index contrast demands wider acceptance angles which, coupled with imperfections, increases the bending loss susceptibility due to inadequate total internal reflection. Therefore, bending losses dominate, rather than minimal reflection because light is weakly guided under bent conditions.
