Step index fiber |
An optical fiber cable, usually multimode, that has a uniform
refractive index in the core with a sharp decrease in
index at the core/cladding interface. The light is reflected
down the path of the fiber rather than refracted as in
graded-index fibers. Step-index multimode fibers generally
have lower bandwidths than graded-index multimode
fibers.
