Abstract
A fiber distribution hub (FDH) includes an internal spool for wrapping a fiber optic cable. The internal spool is adapted to rotate within the FDH and thereby pay out or retrieve the fiber optic cable from/to the FDH. A first end of the fiber optic cable can be extended through an entrance location of the FDH and can be further extended beyond the FDH to a connection point. The second end of the fiber optic cable can be connected to a fiber optic adapter within the FDH and can be disconnected from the fiber optic adapter when the internal spool is rotated. The fiber optic cable can be a fiber optic feeder cable.
Claims29
A fiber distribution hub comprising:
- a cabinet with a first side, the cabinet including at least one door mounted on the first side;
- an entrance location on the cabinet for a fiber optic feeder cable;
- a swing frame mounted within the cabinet, the swing frame being moveable between a stowed position and a service position, the swing frame including a fiber termination region;
- an internal spool adapted to rotate within the cabinet about an axis of rotation, the internal spool including a hub and a cable access opening;
- and
- a fiber optic cable including a first end, a first portion, a second portion, and a second end, the first portion of the fiber optic cable terminated at the first end of the fiber optic cable, the second portion of the fiber optic cable terminated at the second end of the fiber optic cable, the fiber optic cable continuing from the first portion of the fiber optic cable to the second portion of the fiber optic cable, a wrapped portion of the first portion of the fiber optic cable wrapped around the hub of the internal spool, and the second portion of the fiber optic cable being accessible for routing within the cabinet via the cable access opening of the internal spool.

A fiber distribution hub comprising:
- a cabinet with a first side, the cabinet including at least one door mounted on the first side;
- a swing frame mounted within the cabinet, the swing frame being moveable between a stowed position and a service position, the swing frame including a fiber termination region;
- an internal spool adapted to rotate within the cabinet, the internal spool including a hub;
- a fiber optic feeder cable including a first end, a second end, and a wrapped portion between the first and the second ends wrapped around the hub of the internal spool;
- and
- an entrance location on the cabinet for the fiber optic feeder cable;
- wherein the fiber optic feeder cable can be deployed from the fiber distribution hub by rotating the first end of the fiber optic feeder cable through the entrance location on the cabinet and then pulling on the first end of the fiber optic feeder cable thereby rotating the internal spool and unwrapping at least a portion of the wrapped portion.
4 more elements
A fiber distribution hub comprising:
- a cabinet;
- a termination region positioned within the cabinet;
- a multi-fiber fiber optic adapter positioned within the cabinet;
- a splitter module positioned within the cabinet, the splitter module including a plurality of output pigtails each terminated by a first optical connector, the first optical connectors being single fiber optical connectors;
- a plurality of intermediate distribution fibers having first ends terminated by second optical connectors, the second optical connectors being adapted to be coupled to the first optical connectors at the termination region, the intermediate distribution fibers also including second ends adapted for connection to fibers of a distribution cable routed to subscriber locations, the second optical connectors being single fiber optical connectors;
- a spool rotatably mounted within the cabinet;
- a multi-fiber feeder cable wrapped around the spool, the multi-fiber feeder cable including a first end terminated by a first multi-fiber optical connector and a second end terminated by a second multi-fiber optical connector, the multi-fiber feeder cable being deployable from the fiber distribution hub by pulling the first end of the multi-fiber feeder cable from outside the cabinet thereby causing the spool to spin and allow the multi-fiber feeder cable to be paid out from the spool and routed outside the cabinet,
- a plurality of intermediate feeder fibers having first ends and second ends, the first ends of the intermediate feeder fibers being terminated by a third multi-fiber optical connector and at least one of the second ends of the intermediate feeder fibers being adapted for optical connection to an input of the splitter module;
- and
- wherein the second and third multi-fiber optical connectors are coupled together at the multi-fiber fiber optic adapter after the first end of the multi-fiber feeder cable has been deployed.
