摘要:
Fiber optic terminals, systems, and methods for providing differentiated network services to subscribers of a fiber optic network are disclosed. In certain embodiments, fiber optic terminals and methods are disclosed for providing more than one network service to subscribers supported by the same fiber optic terminal. In one embodiment, a fiber optic terminal is provided comprising a first optical path connected to a first network-side optical fiber providing a first network service to a first subscriber-side optical fiber. The fiber optic terminal also comprises a second optical path connected to a second network-side optical fiber providing a second network service differentiated from the first network service to a second subscriber-side optical fiber. In this manner, differentiated network services can be provided to subscribers supported by the fiber optic terminal by configuring connections of the subscribers to either the first optical path or second optical path in the fiber optic terminal.
