Passive Optical LANs
Objectives: From this self-study lesson you should learn:
- What is a Passive Optical LAN?
- What are the differences between regular Ethernet LANs and passive OLANs?
- How passive OLAN systems work
- What are GPON and EPON?
- How passive OLANs fit into structured cabling standards
- How passive OLAN cable plants differ from regular cabling
Passive optical LANs use standard FTTH architecture and protocols which are quite different from typical LANs. A PON (passive optical network) utilizes a passive splitter that takes one input and splits it up to broadcast to many users to cut the cost of the links substantially by sharing one set of electronics and an expensive laser with up to 32 homes. There are three main types of PONs, BPOB, GPON and EPON that are standardized and in widespread use today.
This Fiber U self-study program will introduce you to based on PONs and explain how they work..
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.
Read the references, watch the videos and take the quizzes (Test Your Knowledge)
