6. The FDS of claim 1 , wherein the fiber distribution rack includes a plurality of guides located within the fiber distribution rack for accepting the plurality of splitter modules.
7. The FDS of claim 1 , wherein each splitter module further comprises:
a rectangular sealed enclosure with a face flange on one end of the enclosure and a flange along the longer sides of one face of the enclosure;
a plurality of splitters disposed internal to the enclosure;
a plurality of splice closure (SC) adaptors coupled to the plurality of splitters and positioned on the face flange; and
a pair of fasteners positioned through the face flange and configured to affix the splitter module to the fiber distribution rack.
8. The FDS of claim 7 , wherein the plurality of splitters comprises different types and configurations.
9. The FDS of claim 7 , wherein the pair of fasteners are nylatches.
10. The FDS of claim 7 , wherein the fiber distribution rack includes a plurality of guides for accepting the plurality of splitter modules.
11. The FDS of claim 10 , wherein the flange along the longer sides of one face of the enclosure facilitates front end loading of the splitter module into the fiber distribution rack by placing the flange into a corresponding pair of the plurality of guides.
12. The FDS of claim 11 , wherein the coupling of the longer sides flange and the pair of guides allows the splitter module to be held in an intermediate position.
13. A fiber distribution system (FDS), comprising:
a rack mountable chassis;
at least one fiber distribution rack configured to be mountable to the chassis; and
a plurality of splitter modules configured to be mounted internal to the at least one fiber distribution rack through one face of the at least one fiber distribution rack, comprising:
a plurality of splitters disposed internal to each of the plurality of splitter modules; and
a plurality of splice closure (SC) adaptors coupled to the plurality of splitters.
