  • the patch panel 106 can be affected by manipulation of the resilient arms 240A-B against a natural bias of the resilient arms 240A-B.
  • the patch panel 106 can define one or more alignment rails 248 configured to mate with one or more corresponding slots 250 defined in the bracket 234.
  • single handed insertion is provided. Single handed removal is possible, too, such as by providing only on resilient arm 240A or 240B.
  • the optical fiber management system 100 can include a column of hingedly coupled fiber-optic management trays 104 and one or more patch panels 106, thereby enabling various functions (e.g., splicing, splitting, etc.) to be performed between one or more feeder cables 112 and one or more drop cables 114.
  • one or more groove plate 148 can be preinstalled in the cabinet 102, such that fiber-optic management trays 104 can be snapped into place within the groove plates 148, thereby pivotably coupling the fiber-optic management trays 104 relative to the cabinet 102.
  • the one or more patch panels 106 can be include a pre-terminated optical cable 116, which can optionally include a standardized connector 120 and adapter 122, thereby enabling the pre-terminated cable 116 to be operably connected to the one or more feeder cables 112, for example via a splice or splitter arrangement, which can be coupled to the hingedly coupled fiber-optic management trays 104.
  • Excess cable from the pre-terminated cable 116 can be stored within the cable storage enclosure 183 of the patch panel 106, for example, the excess cable can be wound around the storage spool 194, secured under hooks 198, or retained via cable retainers 186, 186’ or 195.
  • discrete storage of cable slack between trays 104 and patch panels 106 is provided.
  • the amount of slack is varied in cabinet, depending on where the specific tray 104 and connected patch panel 106 are located.
  • the extra slack not needed, due to the specific tray 104 and connected patch panel 106 being relatively close together is stored in the cable storage enclosure 183 of each panel.
  • a bulk storage area for cable slack from all the trays and patch panels can be reduced in size or altogether eliminated by use of the discrete storage of each cable on each patch panel 106.
  • Some slack can be stored around spool 194 during shipping, and then deployed during installation of the tray and patch panel. Any excess cable not needed in after installation, can be placed around spool 194.
  • slack may be would by hand and placed over and then around spool 194 to secure it in area 183. Ties can be used as desired to then secure the final cable deployment to the patch panel 106.
