Fiber Flashcards
1
Q
Mode of Propogation
A
The path a photon takes down a waveguide
2
Q
Index of Refraction
A
The measure of the bending of a light ray as it passes from one medium to another
3
Q
Multi-mode Distortion
A
Light rays with a shorter path length can arrive before ones that where sent before them
4
Q
How do you limit multi-mode distortion?
A
1) limit the length of the cable
2) shrink the diameter of the core
