With the large-scale promotion of fiber-to-the-home (FTTH) in China, the application of various optical passive products has developed rapidly. Important equipment for normal transmission. So how are optical splitters used in fiber-to-the-home (FTTH) cabling?

At present, primary and secondary spectroscopic methods are often used in engineering. For the first-level light splitting method, the use of the optical splitter is generally divided into four situations: one is placed in the central office computer room; the second is placed in the community computer room; the third is placed in the community optical transfer box; the fourth is placed directly in the corridor. For the secondary optical splitting, the use of the optical splitter is generally divided into three situations: one is that the primary optical splitter is placed in the central office computer room, and the secondary optical splitter is placed in the optical cross-connect box; the other is that the primary optical splitter is placed next to the road. In the large-capacity optical transfer box, the second-level optical splitter is placed in the community optical transfer box; third, the first-level optical splitter is placed in the community optical transfer box, and the second-level optical splitter is placed in the corridor.

For example: Suppose the end office is 4km to the community, 4.5km to the community optical communication, and 5km to the user building. There are 20 buildings in the community, each building has 30 households, and all the incoming optical cables in the buildings use leather cable.
