Festoon optical cable

The invention belongs to the technical field of communication optical cable manufacturing, and particularly relates to a festoon optical cable. The festoon optical cable comprises an optical unit and an auxiliary force bearing element which are symmetrically arranged in a crossed mode, the optical unit and the auxiliary force bearing element are twisted to form a cable core, the auxiliary force bearing element comprises a loose tube, a fiber reinforced composite material and fiber paste, the loose tube is filled with the fiber reinforced composite material and the fiber paste, and aramid fiber filaments longitudinally wrap the cable core. The festoon optical cable structure provided by the invention can effectively solve the problems of poor repeated bending performance and the like of a traditional layer-stranded optical cable, has the advantages of excellent repeated bending performance, light weight, excellent wear resistance, excellent environmental resistance, flame retardance and the like, and has good
