Integral seamless reinforced solid light guide optical fiber, buoy tail, buoy and manufacturing method thereof

The invention relates to an integral seamless reinforced solid light guide optical fiber, a float tail, a float and a manufacturing method thereof. The integral seamless reinforced solid light guide optical fiber comprises a light guide optical fiber body, glass fibers and transparent resin, wherein the glass fibers are tightly attached to and wound around an outer surface of the light guide optical fiber body to form a glass fiber net; the transparent resin is filled in gaps and outer surfaces of the glass fiber net and the light guide optical fibers. The float tail is made of the integral seamless reinforced solid light guide optical fiber. The buoy comprises the buoy tail, a buoy body and a buoy foot which are sequentially connected from top to bottom. The light guide optical fiber is protected and reinforced by the glass fiber net and the transparent resin, and a gap between the light guide optical fiber and the glass fiber is seamless, namely solid, so the optical fiber is very firm, good in toughness an
