Understanding Multiplexing



Understanding Multiplexing is an introductory course designed to provide participants with an overview of different multiplexing technologies used in the cable industry. Understanding how these technologies work is key to understanding the way services are delivered to the customers. The course looks at the different versions of time division multiplexing, frequency division multiplexing and wave division multiplexing. We will also explore the basics of using fiber optics to transmit data.


Target Audience:

  • Customer Facing Installers
  • Customer Facing Technicians
  • Service Technicians
  • Headend Technicians
  • System Designers
  • Non-technical managers:
    • Executives
    • Marketing managers
    • Public and government affairs managers
    • Customer service managers


Included in the Course:

  • Engaging and Interactive LightningMod™ to prepare the learner for training 
  • In-depth interactive eBook modules 
  • CORTEX mobile app to access eBook modules in the field 
  • Module assessments
  • Course final exam
  • Fun VirtuGame™ to improve absorption and retention of competencies 
  • SCTE·ISBE course completion certificate
  • 1 recertification units (RUs) towards SCTE·ISBE certification renewal

Requirements for Successful Course Completion:

  • Module quizzes 70% or higher
  • Course final test 70% or higher

You may take the course final test up to 3 times.



The course is delivered online via the SCTE·ISBE virtual classroom, or it may be completed in ½ day (4 hours) as an onsite.


Online learners interact with web-based course materials and complete assessments (quizzes) at a time that is convenient for them. Learners may also contact the instructor when they have questions.


SCTE·ISBE recommends learners spend approximately 1 - 2 hours per week, on average, completing the various course activities in order to maximize the learning benefits. 100% of the schedule is determined by the learners (interacting with online materials, completing quizzes and a final exam).
