What does "pon" mean on the computer router?

Pon refers to passive optical fiber network.

Optical distribution network does not contain any electronic devices and electronic power supply, and ODN is all composed of passive devices such as optical splitters, so there is no need for expensive active electronic equipment.

The technical requirements of passive network are formed on the basis of ATM, and then ITU/FSAN locates G.983 and gives a detailed concept explanation, which is APON.

The first goal of the evolution of optical access network is FTTB (fiber to the building) and FTTC (fiber to the roadside) systems, and then developed to FTTH (fiber to the home), providing users with comprehensive services including data, video and voice through a simple platform.

Passive optical network includes an optical line terminal (OLT) installed in a central control station and a plurality of supporting optical network units (ONU) installed in a user's house.

PON technology was first applied in 1980s. Up to now, its development is full of twists and turns. During this period, the developers who made this kind of equipment and the operators who were responsible for operating this technology put forward many agreements, and the technology also developed in depth to varying degrees, thus making this technology meet the market demand.

EPON can provide higher bandwidth and more comprehensive services than APON, but the cost is very low, and the architecture of EPON also meets most requirements of the G.983 standard.
