Ethernet-based Passive Optical Networks
Two major standard groups, the (IEEE) and the of the (ITU-T), develop standards along with a number of other industry organizations.

What are passive optical networks
A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. Instead of running a separate fiber strand to every home or office, a PON shares a single fiber using optical. They're called "passive" because they don't require any electrical power to distribute the signal once it's sent across.

Bandwidth of Passive Optical Networks
A typical APON/BPON provides 622 megabits per second (Mbit/s) (OC-12) of downstream bandwidth and 155 Mbit/s (OC-3) of upstream traffic, although the standard accommodates higher rates. A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. Abstract—With the rapid advancements in coherent Passive Optical Network (PON) technologies featuring 100G and higher data rates, this paper addresses the urgent requirement for sophisticated simulation and MAC layer development within the domain of coherent Time Division Multiplexing (TDM) PON and. Major standardization bodies like IEEE and ITU-T have introduced several PON solutions to mitigate last-mile broadband.

Three Typical Passive Optical Networks
A passive optical network (PON) is a fiber-optic telecommunications network that uses only unpowered devices to carry signals, as opposed to electronic equipment. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. A PON takes advantage of (WDM), using one wavelength for downstream traffic and another for upstream traffic on a (ITU-T, typically OS2).

WSS is a passive optical device
WSS technology enables network operators to remotely adjust, add, or drop specific wavelengths of light without disrupting other traffic within the network. The Wavelength Selective Switch (WSS) is composed of components such as optical fibers, gratings, waveguides, and. Molex offers WSS products in Single- and Twin- formats, with port counts ranging from Single 1x2 to Twin 1x32+ products. It's an optical device, a circuit pack that performs the following functions: Optical Power Control for Wavelength Switch Nodes.
