Broadband Connections - Fiber Connections

Fiber Optic Technology

Fiber optic technology is used in the core of the Internet due to its higher speeds and longer transmission distances without signal degradation compared to copper cables. Fiber connections use light for data transmission instead of electrical currents.

  • Distance: Electrical signals in copper cables degrade significantly after thousands of feet, requiring repeaters. Fiber connections can transmit data over many miles before signal degradation occurs.

  • Cost: Fiber is more expensive to produce and lay than copper cables.

  • Historical Use: Initially, fiber was primarily used by ISPs within their core networks and in data centers.

  • Current Trend: Fiber is now being implemented closer to end users.

FTTx

The term FTTx (fiber to the x) is used to describe various fiber optic implementations that bring fiber closer to the end user.

FTTN: Fiber to the Neighborhood

Fiber to the neighborhood (FTTN) involves using fiber to deliver data to a physical cabinet that serves a specific population area. From this cabinet, data is transmitted to end users via:

  • Twisted pair copper

  • Coax cables

FTTB: Fiber to the Building/Business/Basement

Fiber to the building (FTTB), fiber to the business, or fiber to the basement refers to using fiber optic cables to deliver data to individual buildings. Connections within the building are then typically made using twisted pair copper.

FTTH: Fiber to the Home

Fiber to the home (FTTH) refers to running fiber optic cables directly to individual residences in a neighborhood or apartment building.

FTTP: Fiber to the Premises

FTTH and FTTB may both be referred to as FTTP, or fiber to the premises.

Optical Network Terminator (ONT)

The demarcation point for fiber technologies is the optical network terminator (ONT), which replaces the modem used in traditional networks. The ONT converts data from protocols compatible with the fiber network to those compatible with twisted pair copper networks.
