Differences between FTTH, FTTC, and FTTN

FTTH, FTTC and FTTN are fiber optic legs they are all made of strands of glass. Fiber optic Internet provides faster, smoother service with more room for signal traffic compared to traditional copper cable wires.FTTH (Fiber to the Home), FTTC (Fiber to the Curb) and FTTN (Fiber to the Node) refer to the wiring path and configuration the signals travel.

How do FTTH, FTTC and FTTN differ?

FTTH (Fiber to the Home)

 the architecture is structured to move between the property line switch box and the residents’ junction boxes. Thereby brings fiber directly to a room in a home or business.Because this installation uses the least amount of metallic cabling, FTTH brings the fastest speeds and the most bandwidth to residences and businesses.The operator houses all the optical switching equipments as required for operation. It’s expensive to install in some areas. Some carriers install fiber optics for this leg as a selling feature in new developments. But, a FTTH home has a disadvantage if a carrier needs to install a separate power line. Power and Internet signals don’t move together in fiber opticsThere are two types of FTTH networks viz. FTTH The point-to-point architecture is typically used for large businesses while the passive optical network (PON) is used for smaller businesses and homes. With this  architecture, just one fiber can be split 32 ways to deliver video, voice and data services to multiple locations. This is a very cost-effective way of delivering fiber services.

FTTC (Fiber to the Curb)

FTTC is a blend of a traditional copper wire cable and fiber optic cable.FTTC is nearly the same as fiber-to-the-node, except it is a few meters closer. While FTTN is more than 1,000 feet away from the home, FTTC is less than 1,000 feet.3 Literally, the fiber-optic cables are brought to the curbs close to a home or business. This is because it is incredibly expensive to install fiber optic cables in a home or a business, so copper is used as an economical substitute.The different subscribers seeking service are connected to the platform by means of twisted pair or coaxial cable. Coaxial cables or twisted pairs then send the signals from the curb to the home. However, bandwidth is lost during this delivery. FTTC can serve several customers within 1,000 feet.

FTTN (Fiber to the Node or Neighborhood)

It is similar to FTTC, A “node” is simply a network box that is shared among multiple homes or businesses. FTTN must be placed far away from the subscriber premises. It covers distance of about 1.5 km radius The remaining distance to the home, often referred to as the “last mile,” can use DSL through existing telephone or cable company lines. Customer proximity to the node and delivery protocols determine data rates. This architecture runs till cabinet which serves neighborhood. While FTTH can offer faster speeds, it is more expensive to install. FTTC or FTTN provides fiber optic Internet to more customers at less expense. To deliver data to more than one customer, a coaxial cable or an unshielded twisted pair cable is typically used.


  1. “FTT” terms are used to describe how broadband is supplied to homes and businesses.
  2. The closer the fiber optic legs reach to the final destination, the better the connection.
