These are based on principle of total internal reflection of light.

These are the fastest transmission media.

SINGLE MODE

• Single stand of glass fiber with a diameter of 8.3 to 10 microns • Relatively narrow diameter of 1310 or 1550nm• Distortion free

MULTI MODE

• Made of glass fibers with common diameters in the 50-to-100 micron range• Fiber core diameters are 50, 62.5, and 100 micrometers
