In the strong breaking force and easy-to-branch optical cable, the strength member is assembled into the subunit and located in the subsheath of the subunit, so that the central strength member can be removed, and the strength member is placed in the subunit, which can also ensure the tensile performance , and at the same time, the sub-units inside the outer sheath can be placed more compactly without the sub-units being significantly increased, thereby effectively reducing the diameter of the overall strong breaking force and easy-to-branch optical cable. To sum up, the strong breaking force and easy branching optical cable can effectively solve the problem that the diameter of the optical cable is difficult to reduce.

Although this device can effectively solve the problem that the diameter of the optical cable is difficult to reduce, it does not support power transmission, and the waterproof effect is not good.
