Optical distribution networks are passive optical networks
An Optical Distribution Network is a passive optical transmission system composed of optical fibers, splitters, distribution frames, and connectors. In practice, PONs are typically used for the last mile between Internet service providers (ISP) and their customers. This is where the network segment will house a control and switch module, and it essentially manages traffic to and from the main fiber connection that services the region.

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.

OTDR optical cable test pulse width
OTDR test pulse width: then set the OTDR test pulse width to the shortest pulse width available, which will provide the highest resolution, giving the best "picture" of the fiber being tested. This is usually listed in nanoseconds (ns), with typical choices of 10 to 30 ns. OTDR settings are a balance between dynamic range, acquisition time, spatial resolution and accuracy. OTDR (Optical Time-Domain Reflectometer) is such a powerful test instruments for fiber optic cable testing: when used properly, it not only simplifies testing requirements, but also help to increase the reliability and value of the network. also depends on the type of network to be characterised (overall length, density of optical devices).
