FOA CFOT Certification Exam v11 Questions and Answers (100% Correct). A fiber optic inspection microscope can increase the danger of high powered light sources by focusing the light coming out of a fiber into your eye. True or False? - ANSWER-True A fiber optic power meter measures absolute power in dBM (dB referenced to 1 mw) and, when used with a light source, can measure insertion loss expressed in dB. True or False? - ANSWER-True When we say 62.5/125 fiber, what does "62.5" mean? -...

What is one of the differences between tree-and-branch and hybrid fiber/coax (HFC) DESIGNS? - Bandwidth in the downstream path. In the tree-and-branch design, the cable signal in the downstream path leaves the trunk at the bridge amplifier. There, It makes a transition to the feeder's domain, and the signal splits. What is the maximum number of output ports the split signal can be routed to? - Four. Which of the following statements accurately describes the relationship between coaxial cab...
