General meaning of term FTTP (fiber-to-the-premises) is the installation configuration of an actual passive optical network.
The application of PON technology that is used for accessing network to homes, small businesses and multiple-occupancy units is called FTTx (fiber-to-the-x). The x is indicating the distance from endpoint to the user.

Some FTTx scenarios

• FTTB (fiber-to-the-business) – is used for direct connection from a central office to the enterprise.
• FTTC (fiber-to-the-curb) – optical fiber cables are connected form the central office to the switch which is allocated in 1000ft (about 300m) from the user. Different transmission cables might be used for connecting from the switch to the user (coaxial, twisted-pair, optical fiber, etc.)
• FTTH (fiber-to-the-home) – similar to the FTTB, but for the business are required larger bandwidths which makes network service provider collect more revenues.
• FTTN (fiber-to-the-neighborhood) – this architecture is having an optical fiber running from ONU to the users,which can be located in up to 1 km (3000 ft). This kind of network can have a speed of up to 20 – 25 Mbps.
• FTTO (fiber-to-the-office) – optical fiber from the central office to a specific office in a building such as a business or apartment house.
• FTTP (fiber-to-the-premises) – includes the use of ONUs for FTTC and FTTN applications and the use of ONTs for FTTB and FTTH implementations.
• FTTU (fiber-to-the-user) – the term of Alcatel fer describing their products for FTTB and FTTH applications.
