Advantage:
1. Greatly reduce the network maintenance cost and installation cost.
2. It has great broadband and fast transmission speed.
3. The optical fiber wiring is not easy to be affected by lightning and rainwater indoors, and there are problems such as optical fiber damage, corrosion or leakage, which has certain safety.
There are many kinds of architectures for optical fiber entering the home, including two kinds: one is point-to-point topology, which uses one optical fiber from the central office to each user; the other is point-to-multipoint passive optical network (PON), which can greatly reduce the number of optical transceivers and optical fiber consumption, and reduce the rack space required by the central office Cost advantage has become the mainstream.
There are two kinds of equipment used for optical fiber access, one is the office equipment deployed in the computer room of the telecom operator, which is called the optical line terminal (OLT), the other is the equipment close to the user end, which is called the optical network unit (ONU). From the current development situation, fiber into the home also involves many industries and categories, such as indoor fiber, engineering and application, which is of strategic significance to the whole telecommunication industry and even the information industry
