Aspects of the present invention disclose a method, computer program product, and system for establishing an optical communication link. The method includes one or more processors controlling an optical detection apparatus to scan an environment to detect at least one marker. The method further includes one or more processors detecting a first marker of the one or more markers, wherein the first marker includes information that indicates a location of a first optical access point. The method further includes one or more processors determining the location of the first optical access point based on an analysis of the first marker. The method further includes one or more processors controlling an optical communication apparatus to align with the determined location of the first optical access point. The method further includes one or more processors establishing an optical communication link between the optical communication apparatus and the first optical access point.
