◉ Modal Distortion. Answer: A light distortion problem unique to
MMF fiber-optic cable. Happens when light signals are sent at the
same time.
◉ chromatic dispersion. Answer: The broadening of a pulse due to
different propagation velocities of the spectral components of the
light pulse. Begins at the light source
◉ Modal Bandwidth is described in terms of.... Answer: (MHz)(km)
◉ Ferrule
Key
Latching Mechanism. Answer: flat or pre-radiused end
assures consistent connector orientation within couplers
locks in place
,◉ Straight Tip (ST). Answer: One of the most common fiber-optic
connectors, similar in style to the BNC connector in coax
◉ subscriber connector (SC). Answer: A square snap coupling for
