Fiber to home

- Jun 24, 2019-

Fiber to home, as its name implies, is a fiber directly to the home. That is, one of the application types of optical access network, the optical network unit (ONU) is placed in the user's home.

FTTH optical fiber to the home, there are two categories: P2P (point to point point point point point to point) and PON (passive optical network passive optical network). On the surface, PON structure can save optical fibers and laser devices. However, because PON is a time-division method, the device speed is required to increase with the increase of PON fraction. In the case of large fraction, high-speed DFB-LD is needed. Its price is 5-10 times higher than that of low-speed FP-LD used in P2P. At the same time, there are also electronic modules for ranging. The cost of the device is high and the cost is not good. However, on the other hand, PON can save pipelines and reduce construction, which is more economical and simple. Therefore, the use of PON is increasing.


In the optical access family, there are also FTTB (Fiber to The Building) optical fiber to the building, FTTC (Fiber to The Curb) optical fiber to the roadside, FTTSA (Fiber to The Service Area) optical fiber to the service area and so on.

Connecting optical fibers directly to the user's home has no limitation on bandwidth, wavelength and transmission technology. It is suitable for introducing various new services. It is the ideal service transparent network and the ultimate way for the development of access network.

Although mobile communication is developing at an alarming speed, due to its limited bandwidth, terminal volume can not be too large, and the limited display screen, people still pursue fixed terminals with relatively superior performance, that is, to achieve fiber-to-home. The charm of optical fiber to the home lies in its huge bandwidth, which is the best solution to the last kilometer bottleneck phenomenon from the Internet backbone to the user's desktop.

In order to break the "last kilometer" of broadband access and meet the technical bottleneck of "ceiling" in broadband technology speed-up based on copper wire, RS-SUNNET has introduced 100-megabit and gigabit optical fiber network card, which realizes the application of 100-megabit and gigabit optical fiber to desktop, such as ultra-fast network operation speed and the network demand of ultra-high-speed storage, download and transmission of data, so as to work and live for users. The speed has been greatly improved, people's network environment has been optimized, and people's network life has been optimized and upgraded.
