First, we should understand: What Is Fiber to The Home Technology?
Fiber to the home (FTTH), also called fiber to the premises (FTTP) (as shown in the following image), refers to the installation and use of fiber optics from a central point directly to individual buildings such as homes, apartment buildings and businesses to provide high-speed Internet access.
In FTTH networks, fiber optic cable is used in the “last mile” to replace DSL and coax, which have lower bandwidths. FTTH dramatically increases the connection speed for computer users compared to the technology used in most places today.
How does FTTH work?
The defining characteristic of FTTH is that it connects optical fiber directly to residences. It uses fiber optics for most or all of its last-mile telecommunications. Fiber optics uses optical signals to transmit data for higher performance.
The FTTH access network is structured as follows: the fiber optic cable starts from a central office, passes through a fiber distribution center (FDH), then through a network access point (NAP), and finally enters the home through a terminal that acts as a junction box.
FTTH Architecture and Components
Two types of systems allow fiber optic cables to use light to transmit data, making FTTH possible. Active Optical Networks (AONs) and Passive Optical Networks (PONs).
AONs use electrically powered switching equipment to direct signals to specific users actively. PONs use optical splitters to produce the movement, rather than electrically powered switches, meaning PON users only need to use electrically powered equipment at the receiving end of the network.
Both types are used in FTTH implementations, and each has its benefits,
but most FTTH implementations use PONs because of their low installation cost and high performance. The network topology of PONs is as follows:
- The provider’s central office has an Optical Line Terminal (OLT).
- An Optical Network Unit (ONU) close to the end-user premises.
- There is an optical distribution network (ODN) between the OLT and the ONU for splitting and distributing the signals transmitted along the PON.
The Application of FTTH
1. CATV Optical receiver: FTTH CATV optical receiver is designed for PON FTTH broadband analog or digital RF/CATV services.
Various types of functions are included, suitable for different applications.
2. Home gateway & IP Terminal: This home gateway/IP terminal series page includes wireless VoIP home gateway, IP phone, IP camera, etc.
With the help of IP cameras, we can quickly build a perfect security and intelligent monitoring system with one cable. IP phone if offering us VoIP calls, voice/video conference, IMS service, UC (Unified Communication)
3. EPON OLT: an integrated access platform that provides integrated access.
EPON OLT series help to simplify the network structure and realize the seamless migration of the FTTx network.
Advantages of FTTH
Internet speed: One of the most significant advantages of FTTH is the improved internet speed. The Internet is continuously becoming the backbone of most communications around the world.
Whether people want to stream videos, download files, or even have video-chats-internet speed is the deciding factor.
FTTH means faster Internet and more bandwidth. Consumers can stream richer media and enjoy higher-quality interactivity. In addition, FTTH can support triple-play services, which means that Internet and TV can be bundled together and provided through one broadband connection.
Technology: When we consider traditional copper, they use analog lines that generate signals through the connected telephone device.
As the description suggests, this technology is less defined, especially when compared with fiber optics.
FTTH is a “future-proof” solution that will facilitate high-speed connectivity capabilities over the long term. Fiber cable has virtually unlimited capacity and is just as cost-effective when it comes actually to delivering service.
Upcoming applications: Various new applications are coming up for FTTH. Hence, by having FTTH- the household stay connected with the latest in technology.
Vector: It is easy to find vendors for fiber to the home, which is another benefit of this all-new technology.
FTTH being the hot topic in much of the industry, Internet Service Providers are working hard to lay the infrastructure needed to allow for higher bandwidth and faster speed internet to the home
Disadvantages of FTTH
The only downside to owning FTTH cable is the cost associated with owning the cable and installing it. Many families may need more time to afford the exact prices. However, there is also a concept called fiber to the home (FTTP), which brings fiber to a specific place. It is less expensive to install than fiber to the home (FTTH).
Deploying fiber to homes is a huge investment that should continue over the next 30 to 40 years. Although each deployment scenario of FTTH has its advantages, there is a significant risk that the short-term savings of PON FTTH deployment on fiber optic infrastructure will significantly affect the future use of expensive fiber optic infrastructure without significant follow-up investment.
