Description: This video discusses the concepts and application of mandrels used for testing multimode fiber optic links.
Pause the video after each objective to answer the review questions below.
QUIZ 1 Question 1: What is the main purpose of a mandrel? To filter out unwanted modes of light Question 2: Mandrels are used for singlemode fibers: True or false False Question 3: What is a mode? A possible path for light to travel in an optical fiber Question 4: What modes are useful for light transmission? Low-order modes Question 5: What is achieved when all unwanted modes of light are lost? Equilibrium Mode Distribution (EMD) QUIZ 2 Question 1: Use of a mandrel is optional for cabling standards that specify mandrel use: true or false? False Question 2: What is the mandrel diameter for 62.5/125 multimode? 0.7" Question 3: What is the mandrel diameter for 50/125 multimode? 0.9" Question 4: What are the three main concerns when making your own mandrel? 1) Make sure the turns do not overlap, 2) the turns are snug around the mandrel, and 3) the fiber is not pulled tightly around the mandrel QUIZ 3 Question 1: What are the two key things to remember when testing multimode fiber links? 1) Do not remove reference cable from light source port, and 2) do not allow reference cable to unwrap from the mandrel
