The embodiment of the invention discloses an optical cable laying method and device, equipment and a medium, and relates to the technical field of electrical engineering. The method comprises the following steps: selecting at least two target equipment models from a pre-established model standard library, and respectively arranging the target equipment models on at least two target positions; establishing a three-dimensional bridge support model between the at least two target positions, and determining a candidate optical cable laying path between the at least two target devices; according toa preset scheme in a pre-established scheme standard library, determining the number of target optical cables, the specification of the target optical cables and the equipment connection relation ofthe target optical cables; and determining a target optical cable laying path according to the candidate optical cable laying path, the target optical cable number, the target optical cable specification, the equipment connection relationship of the target optical cable and the position of the target equipment. According to the embodiment of the invention, the technical effects of short time consumption, low labor cost and less optical cable material consumption when the optical cable laying path is determined are achieved.
