for spliced connection of multi - channel optical - fiber cable ends , the invention contemplates provision of a splice case internally adapted for the storage of excess length of cable in an accumulator and near the splice region , there being a splice mount that is removably secured to the accumulator , so that stored excess cable length will permit selective removal of the splice mount and all its fiber splices to a working location remote from the splice case and its accumulator , all without disturbing the continuous communicating connection of splice fibers not requiring service maintenance or repair . when the servicing operation has been completed , the excess cable length is readily re - coiled into the accumulator , the splice mount is returned to its secured position , and the splice case is re - closed .
