Multiplexing signals together onto a common medium for transport is a practice that is an often-overlooked stage of signal processing. The NCTI® Introduction to Multiplexing course defines time division multiplexing (TDM) and frequency division multiplexing (FDM), the two most common multiplexing schemes that have long been used to transport television and telephone signals through their respective transport mediums. An overview of orthogonal frequency division multiplexing (OFDM) is provided as it has now become commonplace in many applications. Optical multiplexing, which falls under the banner of wave division multiplexing (WDM), requires review of fiber-optic technologies before various levels of WDM can be defined. Detailed explanations are provided of how TDM is used in assorted telecommunications protocols that were first used by the telephone industry before being implemented in many broadband cable networks. This course is beneficial for the technician who works in the hybrid fiber coax (HFC) network or headend recognize their network’s capabilities and limitations.

Completion Time:

The estimated completion time for this course is two hours. The maximum allotted time is four months from enrollment.

Benefits:

  • receive an industry-recognized NCTI certificate of graduation

Upon completing this course, students will be able to:

  1. identify the characteristics of the most common multiplexing techniques
  2. compare the types of wavelength division multiplexing and how they work
  3. describe how time division multiplexing is adapted for different applications

Outline:

Distinguishing Multiplexing Schemes

Discussing optical fiber basics, describing frequency division multiplexing, and assessing orthogonal frequency division multiplexing

Multiplexing Optical Wavelengths

Introduction to understanding wave propagation, defining the electromagnetic spectrum and wavelength, assessing optical fiber modes, defining wavelength division multiplexing, applying wide wavelength division multiplexing, examining coarse wavelength division multiplexing, and discussing dense wavelength division multiplexing

Detailing Time Division Multiplexing

Interleaving data, defining time division multiplexing frames, optimizing TDM efficiency, identifying synchronous TDM applications, and recognizing asynchronous TDM applications
