The Fiber to the room (FTTR) all-optical Wi-Fi solution extends fiber directly to every room, achieving gigabit coverage everywhere in the home.
* FTTR (Fiber to The Room) means using optical fiber instead of network cables, laying optical fiber to each room, and interconnecting with the home gateway by deploying optical network terminals (ONTs). Combined with dual-band WiFi,
a network covering the entire house is formed.
* FTTR is a new model of gigabit home network, which is a technological evolution and upgrade. In the past, the living room was covered with optical fiber, but now it covers every room.
* At present, most families use FTTH networking solutions. FTTH (Fiber to The HOME) technology refers to installing optical network units (ONUs) in users' homes.
FTTH network diagram:
* A typical FTTH network consists of four types of equipment: optical fiber, optical network unit, router, and network cable.
* Optical fiber: connects to OLT upward, provides interfaces downward, and connects to the user's optical network equipment.
* Optical network unit (ONU): converts optical signals into electrical signals according to relevant protocols and interfaces, and connects routers and wired networks downward.
* Router: reads the address in the data packet and determines the transmission path, playing the role of network management in the network. A router can connect multiple network devices.
* Network cable: connects network devices. Common network cables are twisted pair and thin coaxial cable. Thin coaxial cable is simple to connect, but complex to maintain; twisted pair is simple to maintain, but expensive.
FTTR network diagram:
* The FTTR network consists of five types of equipment: the main optical modem, the slave optical modem, the optical splitter, the optical fiber, and the optical fiber panel. The main optical modem and the slave optical modem
are all-in-one devices with WiFi 6 routing.
* Main optical modem: connects to the OLT through XG(S)-PON or 10G EPON, undertakes Gigabit/10G fiber access to the home, and provides an interface for connecting to the optical router.
* Slave ONU: connects to the main ONU through indoor optical fiber, and provides Internet access services to the terminal.
* Optical splitter: realizes the coupling, branching and distribution of optical signals.
* Optical fiber: realizes long-distance transmission of optical signals. PS: When upgrading FTTR with the original network cable, it is required to use Category 5 or Category 6 network cables for home access broadband.
If Category 5 network cables are used, 8 cores are required.
* Optical fiber panel: completes the access and port output of dual-core optical fiber, meets the requirements of optical fiber bending radius and provides safety protection for the fiber core.
3. FTTR vs AC+AP Networking vs Mesh Networking
If you are currently renting a house alone, or if you don't have many terminal devices at home, you may not be able to use the FTTR network for the time being.
So does FTTR networking have greater advantages than other mainstream networking methods? Here we compare the five dimensions of AC+AP networking, Mesh networking, and FTTR networking.
AC+AP networking
AC (Wireless Access Point Controller) is the wireless controller, which connects the wireless LAN to the control device and manages all wireless APs in the wireless network.
AP (Wireless Access Point) is a wireless access point that connects wireless networks and clients.The AP management includes parameter configuration, wireless user authentication, and broadband access.
Many enterprises often use AC+AP networking. With the development of Wi-Fi technology, AC+AP networking can also be applied to achieve home network coverage.
Here is the AC+AP networking diagram:
Mesh networking
Mesh networking is a system of network connectivity in which multiple nodes (devices) are interconnected to distribute data efficiently. Instead of relying on a single central hub, mesh networks use a decentralized model where each node communicates with others, creating a web-like structure. This configuration offers improved reliability, coverage, and scalability compared to traditional networking models.
Mesh networking uses routers that support Mesh to form a hybrid network and expand the signal to places without signals.
Mesh networking is often used in medium-sized houses without reserved network cables.
The diagram of Mesh networking as below:
FTTR's characteristics such as large optical fiber transmission bandwidth, no signal attenuation, and strong anti-interference ability to break through the network speed bottleneck of the original network cable. Therefore, every corner of each room can achieve stable "true Gigabit", and will be upgraded to 10 Gigabit in the future. The network also does not need to change lines.
If you want to upgrade from the current network to the FTTR network, you don't need to worry about the most troublesome network cable laying in the traditional network. Optical fiber can be installed invisibly without destroying the original decoration and layout of the home, and other all-optical equipment can be deployed as needed.
FTTR Invisible fiber cable
Invisible optical cable is the abbreviation for transparent tight-buffered optical cable covered with hot melt glue. It is an optical cable composed of G657A1 G657A2 optical fiber, a transparent tight jacket layer, and a layer of hot melt adhesive. The application of invisible optical cable is the application where the user does not accept the use of leather fiber optic cable to enter the home or solves the problem of the user's difficulty in entering the home, especially in the old residential area and office.
The fiber used is G.657.A1 fiber with a minimum bending radius of 5mm. When laying, there is no need to nail, make brackets, perforate, make pipes, etc., to destroy the original indoor structure, or because of the discontinuity of the laying, the optical cable will sag and fall off and other safety hazards. At the same time, the optical cable is almost transparent so it will not affect the indoor Beautiful, simple construction method, only need hand-held heating installation tools to complete the laying project.
We have below two choice:
1. 1.2mm adhesive invisible transparant fiber optic cable with G657A1/ G657A2 super bent insensitive fiber
2. 0.9mm non-adhesive transparant fiber optic cable with G657A1/ G657A2 super bent insensitive fiber
