　　Optical splitting construction of FTTH network

　　PON is the foundation of FTTH network, and optical splitter is an important part of PON network. There are two types of optical splitting in PON network: first-level splitting and second-level splitting. The first-order spectroscopic method refers to

　　The optical powder routers are concentrated in the optical fiber distribution box, and are directly connected to the OLT at the central office through a single optical fiber, and the other end is connected to multiple ONTs at the user end through multiple optical fibers.

　　The splitting ratio of the optical splitter in the light is usually 1:32 or 1:64.

　　The first-level optical splitting mode: suitable for the city center or town where users are concentrated. The second-level optical splitting mode means that two sets of optical splitters are connected between the OLT and the ONU by cascading. This beam splitting method has two beam splitting points: -first beam splitting point and secondary beam splitting point. The first-level splitting point is usually located near the central office, and a 1 x 4 optical splitter is generally used; the second-level splitting point is generally installed at the user end (such as in a corridor), and there are multiple optical splitters, and a 1 x 8 optical splitter is generally selected. router.

　　The first-level splitting method (centralized distribution of optical splitters) has the advantages of high flexibility, low operating costs and easy maintenance, while the second-level splitting method (cascade distribution of optical powder paths) has faster investment returns.

　　benefits, and low initial investment costs. Therefore, the first-level light splitting method is usually suitable for the city center or town where users are more concentrated, and the second-level light splitting method is usually used in the villages with sparse population distribution.
