Service Technician

The NCTI Service Technician course provides the broadband technician with
fundamental knowledge of the broadband coaxial cable distribution network and
its operation between the distribution taps and fiber nodes. After an overview
of hybrid fiber/coax (HFC) network operation and best practices, the student is
reintroduced to the basics of electricity and Ohm’s law in resistive circuits. The
course examines inductance and capacitance, and how they relate to impedance,
reactance and resonance in the properties of coaxial cable and their applications in
HFC network equipment. This course also describes how to attach hardline coaxial
cable to equipment, splice cables together and common types of passive devices that
are used within the network. Line extender and distribution amplifier operation, the
composition of diodes and transistors and their basic applications, how to use a time
domain reflectometer (TDR) to diagnose and find damaged cable, and signal leakage
and prevention are also covered.
