Description
Technical field [0001] The invention relates to the technical field of outdoor optical fibers, in particular to an outdoor multimode central tube type optical fiber. Background technique [0002] The existing central tube type optical fiber ribbon optical cable is coated with an outer sheath on the outer sheath of the optical fiber ribbon, and two steel wire reinforcements are symmetrically arranged in the sheath. This type of optical fiber cable has poor side pressure and pressure resistance performance, especially in harsh conditions. The optical fiber in the optical cable is vulnerable to damage when laying in the environment. To this end, we propose an outdoor multi-mode central tube fiber. Summary of the invention [0003] The purpose of the present invention is to provide an outdoor multi-mode central tube type optical fiber to solve the above-mentioned background art problems. [0004] In order to achieve the above objective, the present invention provides the following tec...
