Abstract
A fiber optic network having a multi-level architecture is disclosed. A first level of the fiber optic network comprises a first branch. The first branch comprises a plurality of first branch optical fibers optically coupled to a distribution cable and a first branch fiber optic network device. The first branch fiber optic network device is configured to optically couple a first predetermined one of the plurality of first branch optical fibers to a respective first predetermined sub-branch optical fiber, and a second predetermined one of the plurality of first branch optical fibers to a second predetermined sub-branch optical fiber. A second level of the fiber optic network comprises a sub-branch. The sub-branch comprises a first sub-branch fiber optic network device and a second sub-branch fiber optic network device. The first sub-branch fiber optic network device is configured to optically couple a first drop cable with the respective first predetermined sub-branch optical fiber and thereby to the distribution cable. The second sub-branch fiber optic network device is configured to optically couple a second drop cable with the respective second predetermined sub-branch optical fiber and thereby to the distribution cable.
