FSAN Applications

The generation of a service-independent platform providing a high transport capacity

based on the existing infrastructure is the most important goal with respect to the

standardization of new systems for the access network. For FSAN (Full Service Access

Network) there have been several Working Groups working on a special system

configuration. The target of FSAN was to make a specification for:

• Fiber To The Cabinet (FTTCab)

• Fiber To The Curb (FTTC)

• Fiber To The Building (FTTB)

• Fiber To The Home (FTTH).

The FSAN Basic Network Structure is shown below.
