| FTTx is a generic term that describes any network architecture whereby optical fiber is used to replace all or part of the usual copper local loop employed for communication systems. It is geared to deliver multiple advanced services, such as of voice, data & video across one link (triple play) all the way to the homes or businesses. |
| In today's Egyptian market, there are essentially four FTTx technological options: |
Fiber to the Home (FTTH)
A fiber-optic communications path that extends from the operator's switching equipment to at least the boundary of the home living space or business office space. |
Fiber to the Building (FTTB)
A fiber-optic communications path that extends from the operator's switching equipment to at least the boundary of the private property enclosure of homes or offices. In this architecture, the optical fiber terminates before reaching the home living space or business office space. Beyond the termination point, the access path continues over another access medium, such as copper or wireless, to the subscriber.
|
Fiber to the Node/Neighborhood (FTTN)
Generally, it refers to a system whereby fiber is extended to a point, typically a street-side or a cabinet, within a distance of 1,000 to 5,000 feet from the average user. Beyond that point, copper or wireless serves the user. Typically, the service is through a variant of DSL (Digital Subscriber Line).
|
Fiber to the Curb (FTTC)
This option is similar to FTTN, except that the fiber is brought much closer to the user premises, typically closer than 1,000 feet and often closer than 300 feet. In addition to DSL, FTTC installations may use Ethernet (over copper cable or wireless) to bring the signal from the fiber termination point to the user.

FTTH and FTTB Network Architectures
Optical networks are categorized into passive optical network (PON) and active optical network (AON), involving several technical variants in each type.
|
PON
In this type of network, there are no active, electrical, devices between the Central Office and the end user. All the handling of the light beams carrying the signal is done with mirrors, prisms and fiber
|
AON
In this type of network, there are electrical devices (routers and switches) between the user and the central office. More recently, active networks have been designated as “point-to-point” (P2P) networks. This is due to the fact that each end user gets a dedicated fiber (or several dedicated fibers) extending from the Central Office.

Features of FTTH network with GPON technology:
* Neutral - access shared by all service providers
* Scalable – without bandwidth limitation for the future
* Transparent – supportive of final services currently provided by operators
* Open – because of the common IP standards
* Attractive – due to ensuing benefits and cost facilities |
