The disclosure relates generally to cable and, in particular, to a reel enclosure for storing and dispensing cable such as, for example, fiber optic cable. The disclosure further relates to a method for storing and dispensing such cable.
As demand for telecommunications increases, fiber optic networks are being extended in more and more areas. Conventionally, fiber optic enclosures are used to provide a subscriber access point to the fiber optic network. Such a fiber optic enclosures is connected to the fiber optic network through a subscriber cable connected to a network hub. However, the length of subscriber cable needed between the fiber optic enclosure and the network hub varies depending upon the location of the fiber optic enclosure with respect to the network hub. As a result, there is a need for a fiber optic enclosure that can effectively manage varying lengths of subscriber cable.
Conventional fiber optic enclosures include a spool of fiber optic cable provided on an exterior of the enclosure or provided in the interior of the enclosure. When installing fiber optics from enclosure to enclosure, paying out cable from a spool depending on practice can present a variety of issues. If a spool is recessed within the interior of the enclosure, access to the spool becomes limited. On the other hand, if the spool is provided on the exterior of the enclosure, additional equipment or personnel may be required. Also, paying out fiber optic cable and storing slack can require the unwinding and then rewinding of cable, thereby creating waste. This process typically requires the use of outside tooling or extra man power.
It may be desirable to provide a fiber enclosure that can hold the spool in a first position giving maximum accessibility for payout and in a second position for secure storage of the spool.

The door 110 can be pivotally coupled with the base 102, for example, via at least one hinge 105 such that the door 110 is configured to pivot relative to the base 102 between a first closed position (not shown) and a second open position as shown in
For example, in order to facilitate payout of cable from a reel 140 that is mounted to an interior surface 130 of the door 110, the door 110 may form an angle of between 90° and 160° relative to the base 102 in the second open position. In some embodiments, the door 110 may form an angle of 120° relative to the base 102 in the second open position. Of course, the door 110 can be disposed at any desired angle relative to the base 102 in the second open position.

The interior surface 130 of the door 110 may include one or more raised support structures 134, 134′ configured to provide a support for receiving the reel 140 that is spaced from the interior surface 130 of the door 110 so that the reel 140 is held by the door 110 at a position that is outside of an interior cavity 136 of the door 110. One or more of the support structures 134′ proximal to the boss 132 may be configured to cooperate with one or more reliefs 146 cut into the hub 142 to prevent rotation of the hub 142 relative to the door 110 in both the first and second positions of the door 110. The hub 142 is coupled with the reel flanges 144 such that the reel flanges 144 are rotatable relative to the hub 142 about the bearing rim 143. Thus, in the open position of the door 110 shown in
The door 110 may include one or more retention members 138 extending from the interior surface 130 of the door. The retention members 138 may be sized and arranged relative to the reel 140 so as to prevent cable wound on the reel 140 from unwinding beyond the outer circumference of the reel flanges 144. The retention members 138 thereby retain cable wound on the reel 140 within the outer circumference of the reel flanges 144.

The back panel 112 may include first and second wrap guides 127, 128 (“standoffs”) that define an arcuate path for receiving slack fiber optic cable. The first wrap guides 127 define an inner perimeter of the arcuate path that is greater than or equal to a minimum bend radius of the fiber optic cable. The second wrap guides 128 define an outer perimeter of the arcuate path and prevent the slack fiber optic cable from become unwound beyond the outer perimeter. The bend radius of the arcuate path of the wrap guides 127 is generally greater than the minimum permissible bend radius of the cable to prevent signal losses. For example, as the bend radius of an optic fiber or filament decreases, the incident light energy is not fully reflected internally of the optic filament. Accordingly, light energy is refracted out of the filament causing a portion of the light energy to be absorbed or lost.
As discussed above, in some aspects, the back panel 112 is received in the interior 108 of the base 102. The base 102 includes counterbores 116 with a guide hole 118, and the back panel 112 include through holes 126 that align with the counterbores 116 when the back panel 112 is received by the base 102. The counterbores 116 and holes 126 are configured to receive a fastener, for example, a screw, for attaching the enclosure 100 to a structure such as a building, house, wall, or the like. The guide hole 118 facilitates placement of the screw, as would be understood by persons of skill in the art.

It should also be appreciated that a wall of the base 102, for example, wall 106d, may include a pair of grommeted openings 160, 162 configured to receive a conduit, for example, a microduct, or a cable or the like from the outside of the reel enclosure 100.
As shown in
The back panel 112 may include a first support member 164 substantially aligned with the grommeted opening 160 and a second support member 166 substantially aligned with the grommeted opening 162. The first support member 164 may be configured to receive and/or securely hold, for example, a duct received through the grommeted opening 160 from outside the enclosure 100. Similarly, the second support member 166 may be configured to receive and/or securely hold, for example, a duct or a cable received through the grommeted opening 162 from outside the enclosure 100. In some aspects, the second support member 166 may be configured to receive and/or securely hold strengthening members of a reinforced fiber optic cable received through the grommeted opening 162 from outside the enclosure 100.

The mounting panel 210 is lifted in an upward direction relative to the base 202 and rotated to the first closed position shown in
When it is desired to configure a telecommunications system with cable, for example, fiber optic cable, from the reel 240, the cover 205 is pivoted relative to the base to provide access to the interior of the reel enclosure 200. The mounting panel 210 is pivoted relative to the base 202 to the second open position (

The drop cable can be secured to the second support member 166, slack can be wound around the standoffs 127, 128 and can be coupled with the coupling member (e.g., an SC/APC adapter). Once the door 110 is closed, the reel is unable to rotate.
It should be appreciated that features of the two abovementioned embodiments of reel enclosures can be interchanged. For example, in some embodiments, the door 110 of the reel enclosure 100 can be configured as a mounting panel similar to the mounting panel 210 of the reel enclosure 200, in which case the reel enclosure 100 could further include a cover similar to the cover 205 of the reel enclosure 200. Similarly, in some embodiments, the inside surface of the cover 205 of the reel enclosure 200 can be configured similar to the back surface 230 of the mounting panel 210, in which case the mounting panel 210 can be eliminated. Embodiments including the mounting panel may provide an ability to customize the reel enclosure for multiple users. Meanwhile, avoiding the back panel may simplify assembly and/or reduce costs.
Further, it should be appreciated that in some embodiments, the door 110 of the reel enclosure 100 and/or the cover 205 of the reel enclosure 200 can include hinges that include hinge members similar to the hinge members 222 of the reel enclosure 200, and the corresponding wall of the respective base 102, 202 can include hinge receivers similar to the hinge receivers 212 of the reel enclosure 200. Thus, the door 110 of the reel enclosure 100 and/or the cover 205 of the reel enclosure 200 can operate in a manner similar to the mounting panel 210 of the reel enclosure 200 to hold the door 110 and/or cover 205 at a predetermined angle relative to the respective base 102, 202.
