What is the connection between industrial ONU and OLT?

OLT is an optical line terminal, a central office equipment of telecommunications, and is generally directly connected to the BRAS

An industrial-grade ONU is an optical network unit. Multiple ONUs can be connected to an OLT through an optical splitter. The industrial-grade ONU is placed in the user's home as fiber to the home (FTTH), and placed in the building is the light to the building (FTTB).

There is no difference between industrial-grade ONU and PON. ONU is a device, and PON is a technology or architecture.

Both OLT and baiONU are part of the PON architecture. Most of the radio and television networks are connected by EPON+EOC. If it is connected by FTTB+LAN or daoFTTH, the cost incurred in the later period is high, and the cost of transformation investment Also relatively large.

First of all, baiOLT is an optical line terminal, and industrial-grade ONU is an optical network du unit (ONU), and they are all optical transmission network connection equipment. It is the two necessary modules in PON: PON (Passive Optical Network: Passive Optical Network). PON (passive optical network) refers to the (optical distribution network) that does not contain any electronic devices and electronic power supplies. ODN is all composed of passive devices such as optical splitters (Splitter) and does not require expensive active electronic equipment. A passive optical network includes an optical line terminal (OLT) installed in the central control station, and a batch of first-level matching optical network units (ONUs) installed in the user site. The optical distribution network (ODN) between the OLT and the ONU contains optical fibers and passive optical splitters or couplers.
