PON network technology is a point-to-multipoint optical fiber access technology, and consists of an OLT (Optical Line Terminal ) at the office side, ONUs (Optical NetworkUnit, optical network units) at the user side, and ODNs (Optical Distribution Network ). The term "passive" refers to an ODN that does not contain any active electronic devices or electronic power sources, and is composed of passive devices such as an optical Splitter (Splitter).
