A refractive index profile expresses - Answer ✔ the relationship between the ore Ri and
the cladding Ri
Modal dispersion is caused when - Answer ✔ light rays follow different paths along the
fiber core
Graded index fiber overcomes modal dispersion - Answer ✔ increasing the velocity of
rays that travel the farthest
Single mode fibers overcome modal dispersion by - Answer ✔ only allowing one mode
to pass
