The fiber enclosure 100 may include an input port 132 for a hybrid trunk cable (i.e., cable gland 130-9) under the output ports 134 for the six hybrid jumper cables (i.e., cable glands 130-1 through 130-6) and residing adjacent a side wall 112s. The fiber enclosure 100 may include an input port 132 for a power trunk cable (i.e., cable gland 130-10) under the output ports 134 for the six hybrid jumper cables (i.e., cable glands 130-1 through 130-6) and residing adjacent the opposite side wall 112s from the input port 132 for the hybrid trunk cable (i.e., cable gland 130-9). The fiber enclosure 100 may include an input port 132 for a discrete fiber trunk cable (i.e., cable gland 130-11) adjacent to the input port 132 for the power trunk cable (i.e., cable gland 130-10). The two remaining output ports 134 for the hybrid jumper cables (i.e., cable glands 130-7 and 130-8) reside under the output ports 134 for the six hybrid jumper cables (i.e., cable glands 130-1 through 130-6) and between the input port 132 for the hybrid trunk cable (i.e., cable gland 130-9) and the input port 132 for the discrete fiber trunk cable (i.e., cable gland 130-11). Due to their size, the input ports 132 for the hybrid trunk cable and the power trunk cable (i.e., cable glands 130-9 and 130-10, respectively) reside on opposite sides from each other with the remaining output ports 134 for the hybrid jumper cables (i.e., cable glands 130-7 and 130-8) and the input port 132 for the discrete fiber trunk cable (i.e., cable gland 130-11) residing
between the hybrid trunk cable and power trunk cable (i.e., cable glands 130-9 and 130-10) input ports 132.
[0039] Referring now to FIGS. 10A-11B, in some embodiments, the fiber enclosure 100 of the present invention may comprise an optical component panel 140. The optical component panel 140 resides within the interior cavity 120 of the body 110. The optical component panel 140 may comprise a connection wall 140a and a base 140b. In some embodiments, the connection wall 140a of the optical component panel 140 may be substantially perpendicular to the base 140b and may include at least one optical component arrangement 142. In some embodiments, the at least one optical component arrangement 142 may be configured to connect an incoming cable 146 and an outgoing cable 148 (see, e.g., FIGS. 13A-13B).
[0040] In some embodiments, the optical component panel 140 may further comprise an engagement member 160 that is coupled to or integral with the base 140b of the optical component panel 140. The engagement member 160 may be configured such that the optical component panel 140 is removably coupled to a frame 144 within the interior cavity 120 of the fiber enclosure 100. In some embodiments, the frame 144 is coupled to or integral with a floor 122 of the fiber enclosure 100. For example, in some embodiments the optical component panel 140 may be removably coupled to the frame 144 such that the optical component panel 140 is moveable between an engaged position (see, e.g., FIG. 11A) and an unengaged position (see, e.g., FIG. 11B) with the frame 144.
[0041] In some embodiments, the frame 144 may comprise two flanges 144a that extend outwardly from the frame 144. In some embodiments, the engagement member 160 may comprise a spring-loaded mechanism 145 that cooperates with a plurality of protrusions 160a, 162a (or hooks) to engage the flanges 144a of the frame 144. In some embodiments, when the hooks 160a, 162a are engaged with the flanges 144a of the frame 144, the spring-loaded mechanism 145 of the engagement member 160 exerts a biasing force Fb that holds the optical component panel 140 engaged with the frame 144, and thereby secures the optical component panel 140 within the interior cavity 120 of the fiber enclosure 100.
[0042] To remove the optical component panel 140 from the frame 144, a force Fr may be applied to the engagement member 160 to compress the spring-loaded mechanism 145. Compressing the spring-loaded mechanism 145 allows the hook 160a to disengage from the flange 144a of the frame 144. Once disengaged, the optical component panel 140 may be removed from the frame 144 (and the interior cavity 120 of the fiber enclosure 100). In some embodiments, the optical component panel 140 being removably coupled to the frame 144
may provide for easier installation and connection of the incoming and outgoing cables 146, 148 by a technician.
[0043] In some embodiments, the optical component panel 140 may be configured to connect two pairs of fibers. In some embodiments, the pairs of fibers comprise single-mode optical fibers and/or multi-mode optical fibers. In some embodiments, the arrangement of cable glands 130 may correspond to the single-mode optical fibers and/or multi-mode optical fibers. For example, as shown in FIG. 5, in some embodiments, the cable glands 130 within the dashed line (i.e., cable glands 130-1, 130-2, 130-3, 130-7, 130-8, and 130-9) may correspond to multi-mode optical fibers and the cable glands 130 outside of the dashed line (i.e., cable glands 130-4, 130-5, 130-6, 130-10, and 130-11) may correspond to single-mode optical fibers. See also the schematic on the cover 114 of the fiber enclosure shown in FIG. 11A which illustrates the black-colored cable glands 130 corresponding to multi-mode optical fibers and the white-colored cable glands 130 corresponding to single-mode optical fibers.
[0044] In some embodiments, the fiber enclosure 100 of the present invention comprises an electrical component panel 150. The electrical component panel 150 resides within the interior cavity 120 of the body 110. In some embodiments, the electrical component panel 150 may include at least one electrical component arrangement 152. The electrical component panel 150 may be configured to connect a plurality of power connections 156.
[0045] In some embodiments, the electrical component panel 150 may be configured and adapted to receive a pair of power cables from each remote radio unit. In some embodiments, each power cable has a gauge in the range of about 6 AWG to about 14 AWG.
[0046] The foregoing is illustrative of the present invention and is not to be construed as limiting thereof.
