What is Passive Optical Network (PON) ?
What is Passive Optical Network (PON)?
A passive optical network (PON) is a Fiber optic network that uses a point-to-multipoint topology and optical splitters to transmit data from a single transmission point to multiple user endpoints. Passive here refers to the unpowered state of the fiber and its splitting/combining components.
Different
from an active optical network, power is only required at the sending
and receiving points, making PON inherently efficient in terms of
operating cost expenditure. Passive optical networks are used to
simultaneously transmit signals in the upstream and downstream
directions to and from user endpoints.
A Passive Optical Network (PON) is a type of access network that utilizes fiber optic products from a fiber optic products supplier. PONs are used in the telecommunications industry to provide users with access to services such as high-speed data, voice, and video. PONs are cost-effective and reliable, and typically use burst-mode transmission techniques to provide users with bandwidth on demand. Additionally, PONs can be used to connect multiple customers to a single fiber optic line, allowing for easy scalability and cost savings.
Components & Devices Used in PON
Fiber and splitters, requiring no power, are the true “passive” components of the PON. The fiber optical splitter provided by optical splitter manufacturers is not wavelength selective and simply splits optical wavelengths downstream evenly. Splitting optical signal brings a power loss which basically depends on the number of channels the signal is split. The splitter requires no cooling components in active network components (optical amplifiers for example).
Acting
as a starting point of the passive optical network, an optical line
terminal or OLT is connected to a core switch. The main
function of the OLT is to convert, frame, and transmit signals for the network,
and to coordinate the multiplexing of
the optical network terminal (ONT) for upstream transmission. ONT is a
device at the other end (user) of the network which
includes Ethernet ports for home equipment or network connection.
PON Structure
The
PON network adopts a point-to-multipoint structure in which an optical
splitter splits the downstream signal from a single OLT into multiple
downstream paths leading to end users, while the same splitter combines
multiple upstream paths from end users to the OLT.
A PON network
starts with an OLT, from which a fiber feeder cable is routed to the
splitter. The distribution fibers then connect from the splitter to a
drop terminal, which can be easily seen in a street cabinet, on a
telegraph pole, or on the side wall of a building. The drop fibers then
provide the one-to-one connection between the drop terminal port and the
ONU end user.

What is WDM?
Wavelength Division Multiplexing (WDM) is a technique in fiber optic transmission for using multiple light wavelengths to send data over the same medium. Two or more frequencies of light can travel along one fiber, and multiple signals transmit in an optical waveguide at different wavelengths.
