  • Patent number: 4660125
    Abstract: A ribbon cable assembly for interconnection to an electronic equipment pull-out drawer which is arranged so as to occupy a minimum of depth within the drawer while effectively preventing kinking or tangling of the cables as the drawer is opened and closed. This is achieved by folding each of the cables back on themselves so that they individually connect to the back of the drawer at different elevations at connections which are in vertical alignment with one another. In addition the cables overlie each other so that their flat surfaces are orthogonal to the direction of movement of the pull-out drawer.

  • Patent number: 4373776
    Abstract: A protection case for optical fiber splices is in the form of an elongate box having ducts along each side and a plurality of packet members pivotally attached to the bottom of the case in overlapping relationship. A holder in each packet will hold at least one splice, or an attenuator and two associated splices. A cover fastens over the base of the case. The packets have the form of shallow boxes and extra fiber is coiled around in a packet, being retained by turned in edges of the top, sides and bottom.
