Splice-on cable breakout assembly

A cable assembly comprising:

• a first optical cable including a plurality of optical fibers surrounded by a jacket;
• a plurality of second optical cables each spliced to a respective group of the optical fibers of the first optical cable at a respective mass fusion splice, each second optical cable including a plurality of optical fibers, each second optical cable having fewer optical fibers than the first optical cable;
• and
• a housing arrangement extending along a longitudinal axis between a first axial end and a second axial end, the housing arrangement including a first housing piece and a second housing piece that cooperate to define an interior, each of the first and second housing pieces extending between the first and second axial ends of the housing arrangement, the first and second housing pieces being configured to latch together;
• the housing arrangement including a first cable retention region at the first axial end, a second cable retention region at the second axial end, and a splice retaining region disposed between the first and second cable retention regions, the optical fibers of the first optical cable being retained at the first cable retention region by epoxy or adhesive, wherein the housing arrangement includes a barrier wall that inhibits leakage of the epoxy or adhesive beyond the barrier wall, the mass fusion splices between the first optical cable and the second optical cables being disposed at the splice retaining region, the first cable retention region, the second cable retention region, and the splice retaining region being aligned along the longitudinal axis of the housing arrangement.
