1. Understanding FTTH (Fiber to the Home)

FTTH refers to Fiber to the Home, a method of providing internet access directly to individual residences using optical fibers.

This technology allows for an exceptionally high-speed connection because the fiber optic reaches the user’s premises, ensuring no bandwidth sharing.

It encompasses two primary architectures: P2P (Point-to-Point) and PON (Passive Optical Network).

P2P involves direct connections with higher costs due to the electronic modules required for distance measurement.

In contrast, PON is more economical as it saves on fiber and laser components, as well as construction costs, making it increasingly popular.

PON has emerged as one of the most favored solutions for FTTH globally due to its ability to deliver extensive bandwidth and future-proof the network infrastructure.

The main advantages of FTTH:

  • Enhanced network performance, especially over long distances.
  • Increased transparency for different data formats, rates, wavelengths, and protocols due to its passive nature.
  • Simplified maintenance and installation process.
  • Ability to upgrade multiple times without replacing the fiber itself, thus being a future-proof solution.
  • Improved streaming of high-definition video content and faster speeds over longer distances compared to older technologies like coaxial cables, twisted-pair conductors, and DSL.

2. FTTB (Fiber to the Building) Meaning

Fiber to the Building, is an optimized broadband access method that uses fiber optic to reach a building and then relies on copper cables to connect individual units.

FTTB, also known as community broadband, offers a shared bandwidth experience with a typical maximum speed of 10Mbps for both uploads and downloads.

The ONU (Optical Network Unit) or “big modem” is placed within the building, and users connect to it via Ethernet cables.

FTTB Solution

Characteristics of FTTB include:

  • High bandwidth utilization and lower investment costs.
  • Convenient network upgrades, protecting existing network investments.
  • Shared bandwidth, which means the actual bandwidth available to a household is influenced by the number of concurrent users.

3. FTTH vs FTTB: Key Differences

The crucial difference between FTTH and FTTB is the bandwidth and speed provided to the user.

FTTH offers dedicated ONU bandwidth, supporting access speeds up to 1 Gbps.

In the meantime, FTTB‘s shared ONU means that individual user bandwidth is limited, usually not exceeding 100Mbps.

FTTH offers a superior access method, being an ideal solution for integrating voice, video and data services.

FTTB, while practical and economical, has limitations due to its shared bandwidth and the potential loss of speed due to the use of copper cables at the final connection.

4. How to Identify FTTH and FTTB Installations

Examine the equipment

FTTH requires an ONU device (or “modem”) at the customer’s premises, whereas FTTB’s ONU is located in a central location within the building.

Look at the cabling

FTTH uses optical fiber all the way to the user’s home, while FTTB transitions to Ethernet cables in the building’s common areas.

Inspect the size and type of devices

FTTH uses smaller splitters, while FTTB employs larger equipment cabinets.

In conclusion, FTTH is the future-proof technology that supersedes FTTB, offering longer transmission distances, higher bandwidth, and lower operational costs.
