Then, the plurality of main optical fibers 21 exposed at the cut-off portion C are cut off, the main optical fibers 21 are drawn out from the branch portion B to form a plurality of branch optical fibers 31, and the above operations are repeated until the branch portion B matches a predetermined required number, the branch portion B and the cut-off portion C divide the outer jacket 22 into a plurality of pieces, and each branch portion B is located between two adjacent outer jackets 22 along the main axis direction a.
Referring to fig. 3, 4 and 5, in the post-processing step, the branch optical fibers 31 (only one is shown in fig. 3) at each branch B are looped around by a protective sheath 32 as shown in fig. 3 to form a cable branch 3. As shown in fig. 4, a plurality of fixing rings 4 are respectively sleeved on the branch optical fibers 31 of the optical cable branches 3, each fixing ring 4 is fixed on one end of the corresponding optical cable branch 3 connected to the corresponding branch B through kevlar (Kelvlar) and glue to be used as a node, in this embodiment, the fixing ring 4 is a cold-pressed metal ring. Finally, as shown in fig. 5, the outer jacket 22 is connected with a plurality of envelopes 5 to cover and encapsulate the branch B and the cut-off C (the fixing ring 4 is also covered), so that the main optical fiber 21 of the optical cable main body 2 is not exposed. Two ends of each jacket 5 are respectively connected with two adjacent outer covering sleeves 22, and are coated on the optical cable main body 2 in an over-mold (over-mold) or glue-pouring (potting) mode, so that the optical cable system 6 is manufactured.
