Abstract
Disclosed in the utility model is a fiber unit optical cable for a submarine cable. The optical cable comprises a main optical cable, reinforced steel wires (4) and an outer sheath (5). The main optical cable includes a stainless steel tube (3) and one or more optical fibers (1) arranged in the stainless steel tube; and the main optical cable is arranged at the center of the outer sheath (5). The reinforced steel wires (4) are twisted between the stainless steel tube (3) and the stainless steel tube (3); the gap between the main optical cable and the outer sheath (5) is filled with a water-blocking ointment (7); and the gap among all the optical fibers (1) in the stainless steel tube (3) is filled with an optical fiber ointment (2). According to the optical fiber, one layer or multiple layers of reinforced steel wires are twisted at the outer side of the stainless steel tube, an inner sheath is arranged between the stainless steel tube and the reinforced steel wires, and the outer sheath coats the outermost layer, thereby enhancing the compressive property and the extension strength of the optical cable; the inside of the outer sheath is filled with the water-blocking ointment, thereby effectively preventing entering of moisture, improving stability and reliability of optical fiber transmission, and prolonging the service life.
