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.

In a splice case for accommodating splices from individual optical fibers of one multichannel fiber-optical cable end to corresponding optical fibers of another multichannel fiber-optic cable end, wherein said case comprises a frame including two end-wall members of like peripheral contour, and two elongate parallel tie rods rigidly connecting said end-wall members in longitudinally spaced relation, the rod connections being at corresponding peripherally spaced locations on said end-wall members, said end-wall members each having an entry port for through-passage of a different one of the cable ends, and an elongate peripheral-wall closure adapted for removable closure of the included frame volume defined by and between said end-wall members, the improvement comprising an elongate rectangular housing supported by said frame and within said volume, said housing comprising a bottom wall of substantially the longitudinal and transverse extent of said volume, side and end walls upstanding from said bottom wall, a cable-locating core fixed to and upstanding from the bottom wall and of elongate oval configuration and spaced from said side and end walls to define an annular storage volume for coiled accumulation of excess length of one of said cables near the splice region thereof, one of said walls having a port for through-passage of one cable from one end-wall port to coiled accumulation within said annular volume, said core defining with said bottom wall a generally oval storage volume for coiled accumulation of excess length of the other of said cables near the splice region thereof, said bottom wall having a port for through-passage of the other cable from the other end-wall port to coiled accumulation within said generally oval volume, a removable closure for said housing and spanning both said annular and generally oval volumes, and splice-supporting means carried by said closure.
