What does the term "fiber optic network architecture" refer to?

The term "fiber optic network architecture" refers specifically to the layout of components and connections in a fiber optic network. This encompasses how the various elements of the network are organized and interlinked, including the arrangement of fiber optic cables, connectors, switches, and other hardware. Understanding this layout is crucial for ensuring efficient data transmission, optimizing performance, and facilitating troubleshooting.

The physical and logical design of a network involves broader concepts which include not only the layout but also aspects like the protocols and processes governing data flow. While this is relevant, it doesn't define architecture specifically. The software used for managing network traffic pertains to the operational side of a network, which supports performance management rather than the physical or infrastructural layout. Maintenance practices for fiber optic systems focus on the upkeep and repair of the network, which is distinct from the foundational design and configuration that architecture represents. Thus, the focus on layout and configuration makes the chosen answer accurately reflect the concept of fiber optic network architecture.
