FTTB, wifi, and IBS Project

Fiber to the Building (FTTB), also known as Fiber to the Basement, is a type of fiber-optic communication delivery that applies specifically to properties containing multiple living or working spaces. Here are the key characteristics of FTTB:

• Definition:

  • FTTB refers to the deployment of optical fiber up to a central point within a building (such as a basement or equipment room).

  • Unlike Fiber to the Home (FTTH), where the fiber extends directly to individual living or working spaces, FTTB terminates before reaching the subscriber’s specific area.

• How It Works:

  • The optical fiber is connected to a shared property (the building) and distributed within the building using other cabling (such as copper wires or Ethernet).

  • The final connection to individual apartments, offices, or units is completed using existing infrastructure within the building.

• Advantages:

  • Speed: FTTB provides high-speed internet access to multiple users within the same building.

  • Cost-Efficiency: It minimizes the need for extensive fiber deployment to each unit.

  • Scalability: Upgrading services for the entire building becomes more manageable.

• Comparison with Other FTTx Methods:

  • FTTB is distinct from other FTTx methods:

    • FTTH: Fiber extends directly to individual homes or apartments.

    • FTTC: Fiber reaches a cabinet or node near the building, with copper wires completing the connection.

    • FTTD: Fiber extends to a distribution point within the building (similar to FTTB).

In summary, FTTB strikes a balance between cost-effectiveness and high-speed connectivity within multi-unit buildings.
