Abstract
The present disclosure relates to systems and method for deploying a fiber optic network. Distribution devices are used to index fibers within the system to ensure that live fibers are provided at output locations throughout the system. In an example, fibers can be indexed in multiple directions within the system. In an example, fibers can be stored and deployed form storage spools.
Claims21
A cabling system for a multi-dwelling unit having a plurality of floors, the cabling system comprising:
- a plurality of fiber distribution devices disposed within the multi-dwelling unit, each of the fiber distribution devices being disposed at a different floor of the multi-dwelling unit, the fiber distribution devices being daisy-chained together in a vertical chain, each of the fiber distribution devices including a respective closure carrying a plurality of respective fiber lines, the fiber lines of each closure extending from a respective input location, the input location of each fiber distribution device including a respective first multi-fiber optical connector, at least a plurality of the fiber lines of each closure being indexed to a respective first output location, the first output location of each fiber distribution device including a respective second multi-fiber optical connector, and at least a first of the fiber lines of each closure extending to a second output location, the first fiber line being different from the fiber lines of the plurality for each closure;
- and
- a feeder line routed to the input location of a first of the fiber distribution devices in the chain.
A cabling system for a multi-dwelling unit having a plurality of floors, the cabling system comprising:
- a plurality of fiber distribution devices disposed within the multi-dwelling unit, each of the fiber distribution devices being disposed at a different floor of the multi-dwelling unit, the fiber distribution devices being daisy-chained together in a vertical chain, each of the fiber distribution devices including a respective closure carrying a plurality of respective fiber lines, the fiber lines of each closure extending from a respective input location, wherein the input location of each fiber distribution device is formed by a respective stub cable extending outwardly from the respective closure, at least a plurality of the fiber lines of each closure being indexed to a respective first output location, and at least a first of the fiber lines of each closure extending to a second output location, the first fiber line being different from the fiber lines of the plurality for each closure;
- and
- a feeder line routed to the input location of a first of the fiber distribution devices in the chain.
A cabling system for a multi-dwelling unit having a plurality of floors, the cabling system comprising:
- a plurality of fiber distribution devices disposed within the multi-dwelling unit, each of the fiber distribution devices being disposed at a different floor of the multi-dwelling unit, the fiber distribution devices being daisy-chained together in a vertical chain, each of the fiber distribution devices including a respective closure carrying a plurality of respective fiber lines, the fiber lines of each closure extending from a respective input location, at least a plurality of the fiber lines of each closure being indexed to a respective first output location, and at least a first of the fiber lines of each closure extending to a second output location, the first fiber line being different from the fiber lines of the plurality for each closure;
- and
- a feeder line routed to the input location of a first of the fiber distribution devices in the chain;
- wherein, for each fiber distribution device, the input location is defined by a first stub cable, the first output location is defined by a second stub cable, the third output location is defined by a third stub cable, and the closure covers a transition region where the fiber lines are broken out between the first, second, and third stub cables.
