Patent ID: 8737837

Claim:
A fiber optic network including a multi-level architecture, the fiber optic network comprising: a first level of the fiber optic network comprising a first branch comprising a plurality of first branch optical fibers optically coupled to respective optical fibers of 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 one of the plurality of first branch optical fibers to a respective first sub-branch optical fiber according to a first predetermined port mapping scheme, and a second one of the plurality of first branch optical fibers to a respective second sub-branch optical fiber according to the first predetermined port mapping scheme; and a second level of the fiber optic network comprising a sub-branch comprising a first sub-branch fiber optic network device, and a second sub-branch fiber optic network device, wherein the first sub-branch fiber optic network device is configured to optically couple a first drop cable with the respective first sub-branch optical fiber and thereby to the distribution cable, and the second sub-branch fiber optic network device is configured to optically couple a second drop cable with the respective second sub-branch optical fiber and thereby to the distribution cable according to the first predetermined port mapping scheme.
