Abstract

The invention discloses a low bending loss low water peak single mode fiber with a stable diameter. The cladding diameter of the optical fiber is 124-125 mu m, the inner coating diameter is 190-195 mu m, and the outer coating diameter is 240-246 mu m. A production process of the low bending loss low water peak single mode fiber includes the following steps that an F element is added to a core of the optical fiber, the refractive index section of a rod is prefabricated to be a recessed cladding structure, the recessed amplitude is 0.05%-0.14%, and simultaneously, a coating material is subjected to modified optimization. The low water peak single mode fiber is simple in structure, high in practicability, excellent in bending resistance and suitable for being widely used in the industry, simultaneously, stripping performances of coatings are superior to those of similar optical fibers, and the coating stripping time of a single optical fiber is shortened by two seconds.
