FTTx  in NG Networks (Fibre To The x in Next Generation ) is designed to benefit those requiring an in-depth knowledge of the principles and applications of Ten Gigabit and Gigabit Passive Optical Networking and Fibre to the X in NG Networks applications and their associated equipment, its flexibility and function within a modern transmission network.



Technical background in telecommunications.


Topic Areas Include:

Advantages of PON/FTTx Systems

The Variants of the systems

Network Elements and designs

Supported Applications and Network Interfaces

Synchronisation methods in PON Network

Circuit Provisioning and Bandwidth requirements
