Chapter 4 - Fiber Flashcards
True or False: The core diameter can vary from one end of the fiber to the other.
True
True or False: Optical characteristics vary from fiber manufacturer to fiber manufacturer.
True
Legacy and LED fibers are _________
OM1 and OM2
VCSEL and Laser-optimized are __________
OM3 and OM4/5
Why is a mandrel used?
To remove higher order modes and to get a more accurate attenuation value.
Laser-optimized fiber’s are designed for optimal use at what nanometer to match the laser characteristics of a VCSEL?
850 nanometer
