Claim 21:
22. A sealed enclosure including the cable sealant arrangement of claim 1, the sealed enclosure comprising:
a housing that is elongate along a major axis of the housing, the major axis extending along a length of the housing between first and second opposite ends, the housing including a base and a cover that cooperate to define an interior of the housing, the cover being pivotally connected to the base and being pivotally movable relative to the base between an open position and a closed position, the cover defining a front of the housing and the base defining a rear of the housing;
the cable sealant arrangement being positioned at the first end of the housing, the sealant of the cable sealant arrangement including a rear gel volume mounted in the base, a front gel volume mounted in the cover, and an intermediate gel volume positioned between the front and rear gel volumes, the cable sealant arrangement including a first cable entry location defined between the rear gel volume and the intermediate gel volume and a second cable entry location defined between the front gel volume and the intermediate gel volume, the cable sealant arrangement also including a perimeter seal that extends about a perimeter of the housing for sealing between the cover and the base;
a management unit that mounts within the interior of the housing, the management unit being elongate along a major axis that is parallel to the major axis of the housing when the management unit is mounted within the interior of the housing, the major axis of the management unit extending along a length of the management unit between a first end and an opposite second end of the management unit, the first end of the management unit being positioned adjacent to the first end of the housing when the management unit is mounted within the housing, the second end of the management unit being positioned at the second end of the housing when the management unit is mounted within the housing, the management unit including a support infrastructure including a front side and an opposite back side, the support infrastructure including an adapter mounting location and a front cover positioned between the adapter mounting location and the second end of the management unit at a front of the management unit, the management unit also including a rear tray positioned at a rear of the management unit, the rear tray being pivotally coupled to the support infrastructure, the rear tray being pivotally movable about a tray pivot axis that is transverse relative to the major axis of the management unit between an open position and a closed position, the rear tray being located at the second end of the management unit;
splice mounting components mounted to the support infrastructure at a splice mounting location positioned forwardly with respect to the rear tray, the splice mounting components being covered by the rear tray when the rear tray is in the closed position and being accessible from the rear of the management unit when the rear tray is in the open position;
a bank of adapters mounted at the adapter mounting location, the bank of adapters including first portions that face at least partially toward the first end of the management unit and second ports that face at least partially toward the second end of the management unit, the front cover being configured to block access to the second ports from the front of the management unit;
pre-installed fiber optic connectors loaded into the second ports of the fiber optic adapters, the pre-installed fiber optic connectors terminating the ends of pigtail optical fibers that are routed to the splice mounting location;
first cable anchors provided at the first end of the management unit at the rear of the management unit;
second cable anchors provided at the first end of the management unit at the front of the management unit;
wherein, in use:
a) a pass-through cable is routed through the first cable entry location, is anchored to the rear of the support infrastructure by the first cable anchors, has a portion stored in a cable loop at the rear tray, and includes optical fibers that are accessed from a mid-span location of the pass-through cable within the housing and that are spliced to the pigtail optical fibers at the splice mounting location; and
b) drop cables are routed through the second cable entry location and anchored to the front of the support infrastructure by the second cable anchors, the drop cables having connectorized ends that plug into the first ports of the fiber optic adapters.
