PON has now became a popular network technology all over the globe.
It first came in to being in 1995. The International
Telecommunication Union (ITU) standardized two initial generations
of PON – APON and BPON. And the advancement of PON network has
never stopped. Until now, the recent PON standard of NG-PON2 has
been put forward in 2015. With the maturity of PON, people are more
easily accessible to networks today. But what does PON exactly
mean? What’s the composition of PON network? The following part
will give you the answer.

PON, also known as passive optical network, is a technology in
telecommunication that implements a point-to-multipoint (P2MP)
architecture. Unpowered fiber optic splitters are used to enable a
single optical fiber to serve multiple end-points such as customers
instead of providing individual fibers between the central office
(hub) and customer. According to different terminations of PON, the
network system can be divided into fiber-to-the-home (FTTH),
fiber-to-the-curb (FTTC), fiber-to-the-curb (FTTB), etc. To be
specific, a PON is made up of an optical line terminal (olt) at the
service provider’s hub and a number of optical network units (ONUs)
or optical network terminals (ONTs) near end users. And “passive”
is just used to describe that no power requirement or active
electronic component is included for transmitting signals in the
EPON or Ethernet PON uses the Ethernet packets instead of ATM
cells. Upstream and downstream rates of EPON are able to achieve up
to 10 Gbps. It is now widely applied to FTTP or FTTH architecture
to serve multiple users. With the advantages of scalability,
simplicity, multicast convenience and capability of providing full
service access, many Asian areas adopt EPON for their networks.
