Question 2

Fiber

Answer 2

Single-mode: ▪ Used for longer distances and has smaller core size which allows for only a single mode of travel for the light signal
▪ SMF’s core size is 8.3-10µ in diameter

Multi-mode: Used for shorter distances and has larger core size which allows for multiple modes of travel for the light signal.
▪ MMF’s core size is 50-100µ in diameter
▪ Up to 2 kms or less
