Fiber optic distribution network (ODN) is divided into five sub-systems: center office subsystem, trunk cable subsystem, distribution cable subsystem, introducing cable subsystem, and fiber optic terminal subsystem.
一、 FTTH whole layout
二、FTTH Network Mode one: Centralized optical splitter placement formula (First level optical splitting mode)
Centrally located formula is divided into the community room type and optical cross connection cabinet. Accessed from the central office to the community room or optical cross connection cabinet, the optical fiber enters into the fiber distribution box through fiber splitter, then connects to connect ONU according to the user's need. First level optical splitting is mainly used in a variety of scenarios of the new district and transformation of the old district.
三、FTTH Network Mode 2: dispersion optical splitter placement formula (Secondary level optical splitting mode)
Secondary optical splitting construction program is mainly for small user groups for the initial stage, while reducing the cost of initial investment, especially for the rural areas or urban villas.
