An input member extends outwardly from the base. At least a portion of the input member extends along the bottom of the termination enclosure. The input member defines a sealed input passage that extends through the base. A sealing chamber is defined by the base and cover. A gasket disposed at the sealing chamber seals and/or retains drop cables routed into the enclosure even when the cover is moved relative to the base. The sealing chamber defines ports that are located on a common side of the enclosure as an end of the input member. ## Claims ### Claim 1 A termination enclosure for optical fiber cables comprising: a base defining a bottom of the termination enclosure and partially defining sidewalls of the enclosure extending upwardly from the bottom; a cover moveably coupled to the base to provide access to an interior of the enclosure, the cover defining a top of the termination enclosure and partially defining the sidewalls of the enclosure extending downwardly from the top; at least one optical component disposed within the interior; an input member that extends outwardly from the base, at least a portion of the input member extending along the bottom of the termination enclosure, the input member defining a sealed input passage that extends through the base, the sealed input passage extending between an outer port at a distal end of the input member and an inner port that provides access to the interior of the enclosure from the input passage; and a sealing chamber defined by the base and cover at which a gasket is disposed to seal a plurality of drop cables routed through the enclosure, the gasket being configured to provide retention of the drop cables even when the cover is moved relative to the base, the sealing chamber defining ports through which the drop cables are routed into the interior, the ports and the outer port of the sealed input passage being located at a common side of the termination enclosure. ### Claim 2 (depends on 1) The termination enclosure of claim 1, wherein the optical component includes a sliding module. ### Claim 3 (depends on 2) The termination enclosure of claim 2, wherein the sliding module includes one or more adapter packs. ### Claim 4 (depends on 2) The termination enclosure of claim 2, wherein the sliding module includes one or more parking modules. ### Claim 5 (depends on 2) The termination enclosure of claim 2, wherein the sliding module includes one or more optical splitters. ### Claim 6 (depends on 1) The termination enclosure of claim 1, wherein a rear of the enclosure is generally solid and the cover attaches to the base at the rear of the enclosure. ### Claim 7 (depends on 1) The termination enclosure of claim 1, wherein the inner port is defined through the bottom of the termination enclosure. ### Claim 8 (depends on 1) The termination enclosure of claim 1, wherein the inner port is defined through a front of the termination enclosure. ### Claim 9 (depends on 1) The termination enclosure of claim 1, further comprising a feeder cable precabled through the sealed input passage prior to deployment of the termination enclosure. ### Claim 10 (depends on 9) The termination enclosure of claim 9, wherein the feeder cable is a stub cable that has a first end that is disposed within the interior of the enclosure, an intermediate section that extends through the input passage, and a second end that is disposed outside the enclosure. ### Claim 11 (depends on 10) The termination enclosure of claim 10, wherein a length of the stub feeder cable ranges from about fifty feet to about one hundred feet. ### Claim 12 (depends on 10) The termination enclosure of claim 10, wherein a length of the stub feeder cable ranges from about forty feet to about eighty feet. ### Claim 13 (depends on 10) The termination enclosure of claim 10, wherein a length of the stub feeder cable ranges from about 80 feet to about 120 feet. ### Claim 14 (depends on 10) The termination enclosure of claim 10, wherein the stub feeder cable includes multiple optical fibers. ### Claim 15 (depends on 10) The termination enclosure of claim 10, wherein a first end of the stub feeder cable located within the interior of the enclosure is terminated by at least one optical connector. ### Claim 16 (depends on 15) The termination enclosure of claim 15, wherein a second end of the stub feeder cable is unterminated. ### Claim 17 (depends on 15) The termination enclosure of claim 15, wherein a second end of the stub feeder cable is terminated by at least one single fiber connector. ### Claim 18 (depends on 15) The termination enclosure of claim 15, wherein a second end of the stub feeder cable is terminated by at least one multi-fiber connector. ### Claim 19 (depends on 15) The termination enclosure of claim 15, wherein a second end of the stub feeder cable is terminated by a ruggedized connector. ### Claim 20 (depends on 1) The termination enclosure of claim 1, wherein the sidewalls of the base are taller towards a rear of the enclosure and shorter towards a front of the enclosure.
