Aerial optical cable connection installation device and method

The invention provides an aerial optical cable connection installation device, which is characterized in that an optical fiber connection box (13) is arranged on the lower portion of an iron tower (12), optical fibers (8) and an aluminum stranded wire are arranged in an OPGW optical cable (1), and the installation device comprises an inner protective bushing (6), an outer protective bushing (3), astainless steel protective pipe (7), a fastening sleeve (5), a winding protective sleeve (4) and a waterproof sleeve (2). According to the method, an OPGW optical cable is cut after a reserved cable(10) is reserved, and then the end of an aluminum stranded wire is fastened through a fastening sleeve; coating is performed with water-blocking paste within a certain distance in front of and behindthe fastening sleeve, reserved continuous optical fiber is coated with silicone grease, an inner protective bushing is arranged on the optical fiber, and a winding protective bushing completely sleeves outside the inner protect
