Optical splitter application scenarios

The optical splitter, commonly referred to as OBD, is an essential tool for accessing FTTH. An operator in the communication industry typically uses this passive device on the home broadband side to access its benefits and meet customer needs effectively.

One side of the OLT in the equipment room connects the optical cable to the fiber distribution box (optical box) through the OLT terminal side, while the other side connects to the terminal (optical terminal). It is essential to note that there are two possible situations in this setup.

In rural areas and shops, the first-level spectroscopic use scene calls for the use of first-level mode. The optical boxes and other equipment necessary for this mode are quite large and can accommodate equally large optical splitters. These splitters are directly connected to the user's optical modem (ONT) located within their home.

The second-level mode is utilized in cities where both first-level and second-level light splitting are required. Typically, these optical splitters are found in the optical cross-connect boxes located in residential areas. This involves first-level splitting using the second-level mode, followed by second-level splitting using the second-level mode on the corridor end, and finally leading to the optical modem (ONT) on the user's side. It is a highly efficient and effective method for distributing optical signals in densely populated areas.
