Optical Cable Splice Cassettes With Slack Covers

A splice cassette for optical cables, the splice cassette comprising:

• a tray base having a tray top surface and a tray bottom surface;
• a plurality of optical cables coupled to an adapter panel having a plurality of optical connectors for connecting the plurality of optical cables to at least one external device, wherein at least a portion of the optical cables is jacketed or bundled together as a slack cable;
• a tray center portion defined on the tray top surface inside a center-portion periphery;
• a plurality of tray cable retaining securing members arranged around a center-portion periphery, the plurality of tray cable retaining members guiding the optical cables around the center-portion periphery;
• a transition passage through which the slack cable is routed from the tray top surface to the tray bottom surface;
• a tray-bottom substructure protruding from the tray bottom surface below the tray center portion of the tray top surface;
• a continuous slack passage defined outwardly on the tray-bottom surface from a substructure wall of the tray-bottom substructure, the continuous slack passage comprising a first slack region and a second slack region on opposite sides of the tray-bottom substructure, the slack cable being routed at least once around the continuous slack passage;
• a first slack cover hingedly attached to a first outer edge of the tray base, the first slack cover enclosing at least a portion of the first slack region in a closed position of the first slack cover;
• a second slack cover hingedly attached to a second outer edge of the tray base, the second slack cover enclosing at least a portion of the second slack region in a closed position of the second slack cover;
• and
• a slack exit through which the slack cable passes from the first slack region or the second slack region out of the splice cassette.
