Butterfly-shaped optical cable and prefabricated terminating optical cable using same

The invention belongs to the technical field of cables, and particularly relates to a butterfly-shaped optical cable which is provided with two subunits and is characterized in that each subunit is composed of a reinforcing part, an optical communication part and a subunit main body, each subunit main body is composed of a protection part, a reinforcing part protection layer and a limiting part, and in the same cross section, the two subunit main bodies are connected in a clamped mode. The reinforcing member protection layer of one sub-unit main body is located in the protection component of the other sub-unit main body, and the reinforcing member and the optical fiber are located in the reinforcing member protection layer; the device has the beneficial effects that the structure is simple, the subunits can be independently wired, the subunits can be self-supporting suspended wired, and the protection effect is good; the invention further discloses the prefabricated end forming optical cable. 本发明属于线缆技术领域，尤其是涉
