System Technician

The NCTI System Technician course provides foundational information that can help
accelerate a broadband cable technician’s career path advancement. One of the courses
included in NCTI’s Master Technician certification, the System Technician course, is
intended to elevate the student’s understanding of how hybrid fiber/coax (HFC) network
equipment operates down to the component level. The student will study principles of
amplitude, frequency and phase modulation, which remain integral in modern digital
modulation schemes. The course covers the basic circuits that are within most equipment
being serviced in today’s broadband cable networks, power supply and amplifiers.
Amplifier operations in broadband cable network applications is first described before a
detailed explanation of how to align HFC distribution amplifiers is presented. Proactive
Network Maintenance (PNM), a feature of DOCSIS 3.1, is explained along with the basics
of spectrum analyzers and network sweeping. The course also includes a description of
the equipment and techniques used for underground construction. The value of this
foundational information becomes apparent when the broadband cable technician
successfully troubleshoots and resolves escalated problems.
