What is graded index fiber?

• A type of fiber that conducts electricity

• A type of fiber that is only used in telecommunications

• A type of optical fiber with a core where the refractive index decreases as the distance from the center increases.

• A type of fiber used in knitting

How are single mode fiber and graded index fiber different?
