Abstract

An optical fiber comprises a fiber core and an inner coating coated on the external surface of the fiber core. The optical fiber is spiral and further comprises an outer coating coated on the inner coating, wherein the outer coating comprises the following components by mass percentage: 40-70% of natural rubber, 20-50% of chloroprene rubber, 0-6% of magnesium oxide, 0-6% of zinc oxide and 0-6% of vulcanization accelerator. The optical fiber is in a spiral structure; the outer coating of the optical fiber comprises the natural rubber with higher elasticity and the chloroprene rubber with higher mechanical strength; and the optical fiber can extend when being stretched by an external force, and can return to an initial state after the external force disappears, so that the optical fiber has a certain extension scope to meet the requirements of optical fiber transmission of different distances. The invention further provides a manufacturing method of the optical fiber.

Description

technical field [0001] The present invention relates to an optical fiber and its manufacturing method. Background technique [0002] With the large-scale application of fiber to the home (Fiber To The Home, FTTH), the use of optical fiber becomes wider and wider. The optical fiber socket or optical fiber plug used by ordinary users is usually connected with a section of optical fiber. Since the core of the optical fiber is made of glass fiber, it is not easy to bend. To avoid optical fiber bending, ordinary users usually need to specify the length when purchasing optical fibers. Too short or too long optical fibers will cause inconvenience to users. Contents of the invention [0003] In view of the above situation, it is necessary to provide an optical fiber with a certain stretching range and a method for manufacturing the optical fiber. [0004] An optical fiber comprising a core and an inner coating coated on the outer surface of the core. The optical fiber is helica...
