A FiberLink is used to represent a unidirectional physical connection between two ports, which is always an optical fiber. A FiberLink has the relationship Feeds with each of the ports to which it is connected.
These relationships are shown in FiberLink relationship with ports. In this figure, generic labels (InputPort) and (OutputPort) indicate that FiberLink objects represent fibers that connect to any of the types of port represented in the Optical Transport Manager for WDM.
