Non-metal outdoor optical cable for communication

The invention belongs to the field of optical cables, and discloses a non-metal outdoor optical cable for communication, which comprises a cable core (1), a non-metal reinforcer layer and an outer sheath, the optical cable is characterized in that the cable core is composed of 3n identical bending parts (11) and a reinforcing part, each bending part is composed of a bending body (113) and an optical fiber ribbon located in the bending body, the bending parts are divided into three stacked bodies after being stacked in the same bending direction with n bending parts as a group, n is a positive integer, and on a plane perpendicular to the axis of the optical cable, n is a positive integer; a center cavity (10) is defined by the inner surfaces of the three stacked bodies, the outer surfaces of the three stacked bodies and the first side faces of the three stacked bodies form the outer surface of the cable core, the reinforcing component is located in the center cavity, and the three stacked bodies are attached t
