Progression: Field Tech II - III Conventional Exam 2024 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 t...

Progression: Maintenance Tech I - II Conventional Questions and Answers 100% Pass In the tree-and-branch architecture, how is the downstream signal from the trunk fed to the distribution branches? Within each trunk amplifier, a portion of the downstream is fed to a bridger amplifier to boost the signal before being split and routed to the distribution branches. What is a common solution when congestion from modem activity and traffic becomes unacceptable in a hybrid fiber/coax (HFC) network? N...

Progression: Construction Coordinator I - II Exam Answered Correctly. A chain trencher A return path sweep-and-alignment system is used to adjust which of the following? Anomalies, such as echoes and blind spots, can hide cable faults or cause a technician to misinterpret the signature of a time domain reflectometer (TDR) waveform. What causes an echo on a waveform TDR? As the RF signal travels on the coaxial cable, one portion of the signal may be attenuated more than the others. ...
