FTTH, fiber for the home, you know. Provides access technology to the end customer. There is a situation that fiber optic cables extend to the ONU (Optical Network Unit) depending on the customer’s facilities, they also provide the customer with virtually unlimited bandwidth for all applications such as video, voice and data High speed, and the speed can reach up to 1G per customer. Related passive optical product: PLC splitter. And FTTH is a test of the future, it becomes the only technology that can meet the requirements for such a high bandwidth, the FTTH architecture is shown in Figure.
We know that ONU is required for each client rather than for a group of up to several hundred clients. FTTH is not profitable at the moment, and depends on technological advances to provide more cost-effective bandwidth in fiber optic cables and effective UN technology.
Well, FTTH will be the preference of many people. After a thorough understanding, we can know that the easiest way to provide FTTH is to use a passive 1: N optical splitter to divide the optical bandwidth approximately equally among the N clients. Alternatively, a single fiber can also be applied for both transmission directions using Wavelength Division Multiplexing (WDM). The division of optical power among many consumers in a PON (passive optical network) has a significant optical power budget.
In recent years, FTTH has some developments, such as a proposal for the creation of a GNDG (National Gigabit Data Network), it may exceed the bandwidth communication requirements for the future and the proposal also allows the use of technologies Access alternatives, already discussed, such as XDSL, coaxial or wireless to provide service at lower data rates. However, the interface with such solutions can cost almost as much as the final FTTH infrastructure. In fact, WDM with optical splitters or optical amplifiers are the main technologies necessary to implement such an FTTH network. Now, WDM systems can provide 40G bandwidths per fiber, use 16 wavelengths at 2.5G each, and hope it can reach 100 rerabits in the next 5 years.
