NetBox models cables as connections among certain types of device components and other objects. Each cable can be assigned a type, color, length, and label. NetBox will enforce basic sanity checks to prevent invalid connections. (For example, a network interface cannot be connected to a power outlet.)
Either end of a cable may terminate to multiple objects of the same type. For example, a network interface can be connected via a fiber optic cable to two discrete ports on a patch panel (each port attaching to an individual fiber strand in the patch cable).
