What is PON ? Why we call it Passive Optical Network?

Today we are going to talk about a topic “ PON “, what is PON? Why we call it Passive Optical Network?

A passive optical network ( PON ) is a fiber optical network utilizing a point to multipoint topology and fiber optical splitters to deliver date from a single transmission point to multiple user endpoints. 

Passive, in this contect, refers to the uppowered condition of the fiber and fiber optical splitting/ combining components.

In contrast to an active optical network, electrical power is only required at the send and receive points, making a PON inherently efficient from an operation cost standpoint. Passive optical networks are used to simultaneously transmit signals in both the upstream and downstream directions to and from the user endpoints.
