ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to fiber-optic cable routing and storage devices and, more particularly, to a fiber-optic cable routing and storage device for use in a fiber optic-cable enclosure and that provides fiber-optic cable storage in a relatively small area while ensuring a minimum bend radius for the stored fiber-optic cable.
BACKGROUND OF THE INVENTION
Fiber-optic cable may be stored in enclosures having a relatively small footprint (i.e., small volume) and that can accommodate a significant length of fiber-optic cable. In such enclosures, it is desirable to manage the length of stored cable and to ensure that the cable is not damaged by excessive bending or otherwise. It is also desirable to provide a cable guide that does not impeded access to other components, devices, connectors, etc. provided within or as part of the enclosure.
SUMMARY OF THE INVENTION
The present invention is directed to a fiber-optic cable routing and storage device that accommodates a significant length of fiber-optic cable in a relatively small footprint and that ensures that a minimum bend radius is provided for the stored cable.
In a first embodiment of the present invention, a fiber-optic cable routing and storage device for use in a fiber-optic cable enclosure comprises a first generally U-shaped part and a second generally U-shaped part that together define a continuous fiber-optic cable routing path over which a fiber-optic cable may be routed. The routing path comprises a first routing part having a first section, a transition, and a second section. The fiber-optic cable is routable over the first section in a first direction, over the transition in a direction generally transverse to the first direction, and over the second section in a direction generally opposite of the first direction. The routing path also comprises a second routing part over which the fiber-optic cable may be routed in a direction generally orthogonal to the second direction.
In another embodiment of the present invention, a fiber-optic cable routing and storage device for use in a fiber-optic cable enclosure comprises a continuous fiber-optic cable routing path over which a fiber-optic cable may be routed. The routing path comprises a first surface including a generally planar part and a generally arcuate part, and a second surface disposed generally orthogonally with respect to the first surface and including a generally planar part and a generally arcuate part. The fiber-optic cable is routable continuously on the cable routing and storage device over the first and second surfaces.
Other objects and features of the present invention will become apparent from the following detailed description, considered in conjunction with the accompanying drawing figures. It is to be understood, however, that the drawings, which are not to scale, are designed solely for the purpose of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims.
