What is one reason why broadband cable operators install fiber-optic cable in stages instead of changing the infrastructure all at once? Answer Changing the infrastructure all at once would cause too many service disruptions. What is the difference between the fiber-to-the-node (FTTN) and fiber-to-the-curb (FTTC) topologies? Answer An FTTC is allowed a smaller number of RF amplifiers between the optical fiber and the customer premises. Which type of star topology used in a passive optical ...

What are three principle characteristics that define an AC waveform? - Answer- The three principle characteristics that define an AC waveform are: (1) frequency; (2) wavelength; and (3) amplitude. What is one of the basic principles of resistance reflected in the familiar practices of grounding and bonding? - Answer- Grounding and bonding practices reflect the basic principle that electricity always follows the path of least resistance. What comprises the impedance of a coaxial cable or a ...
