FTTx Architectures

Objectives: From this self-study lesson you should learn:
  • What are the varieties of FTTx?
  • What are the limitations of networks that don't take fiber all the way to the home?
  • How man varieties are there of wireless broadband?
  • What are "active star" networks?
  • What is a PON and how is it implemented?
  • What varieties of PON architectures are possible?

New network architectures have been developed to reduce the cost of installing high bandwidth services to the home, often lumped into the acronym FTTx for "fiber to the x". These include FTTC for fiber to the curb, also called FTTN or fiber to the node, FTTH for fiber to the home and FTTP for fiber to the premises, using "premises" to include homes, apartments, condos, small businesses, etc. Recently, we've even added FTTW for fiber to wireless.

This Fiber U self-study program will introduce you to the various options for FTTx networks and discuss some of the ways they are implemented.

The course leads you to read online or printed materials (with an emphasis on the online using the FOA Guide), watch FOA YouTube Videos, complete some activities and take the quizzes. Each lesson plan will be self-contained. Lesson plans open in new pages so the course overview page stays open to lead you to the next lesson or you may use the link at the bottom of the page.
