Abstract: A rear panel door for an enclosure box (e.g., of a network or computing module) is attached to the enclosure module without the use of conventional hinges, instead using pins and hooks to hold the panel door onto the enclosure module. Lower hooks provide rotation for opening and closing the panel door, as well as for securing the panel door to the enclosure module while the panel door is in the open position. Upper hooks provide a latching feature to secure the panel door to the enclosure module when the panel door is in the closed position. The door can be opened directly from the rear side of the enclosure module (e.g., using integral finger holes or slots formed in the panel door and/or enclosure module) or by applying an interior pressure from within the enclosure module.

Abstract: A water-tight fiber optic ribbon communications cable constructed without the use of gel or grease in the buffer tube(s) thereof. A plurality of water-blocking yarns are provided around at least a portion of the stack of fiber optic ribbons loosely positioned within the buffer tube(s) that possess water swellable characteristics. The swell capacity of the plurality of water blocking yarns exceeds the critical mass of water that could enter the buffer tube(s) by a factor of 2.0 or more. Optionally, superabsorbent powder can be applied between and/or on the fiber optic ribbon stack.
