Embodiment Construction
[0011] The present invention is described in detail below in conjunction with accompanying drawing:
[0012] A self-supporting butterfly optical cable that can overcome the influence of stripping grooves on the protection strength of optical fibers, including an upper protective sheath 1, a lower protective sheath 4, a sling 3, a suspension wire 2, a strengthening core 5, a loose tube 6 and an optical fiber 7. An optical fiber 7 is arranged in the loose tube 6, and a suspension wire 2 is arranged in the upper protective sheath 1. The upper protective sheath 1 is connected with the top surface of the lower protective sheath 4 through a sling 3, and the cross section of the lower protective sheath 4 is rectangular. The central axis of the lower protective cover 4 coincides with the central axis of the loose tube 6, and two pairs of stripping grooves 8 with a right-angled triangle cross section are symmetrically arranged on both sides of the lower protective cover 4; The extensio...
