What are the current trends? About Passive Optical Networks (PON)


What is a passive optical network?

A passive optical network (PON) is an optical network with one-to-multiple connections that divides downstream optical signals via a splitter with an optical line terminal (OLT) for multiple optical network terminals or optical network units (ONU). Except for the terminal equipment, the whole optical distribution network (ODN) contains no components that use electricity and is formed by only passive components like the splitter.

Composition of PON:

Currently, there are two mainstream PON standards: one is the ITU-T G.98x series of the International Telecommunication Union (ITU), which includes ATM PON (APON), Broadband PON (BPON), Gigabit Capable PON (GPON), and 10 Gigabit Capable PON (XG-PON); the other is the IEEE 802 EFM series, which includes Ethernet PON (EPON) and 10G-EPON.
