The present invention relates to a cable fiber communication line. The cable fiber communication line comprises a conductor core layer and a protective jacket layer. The protective jacket layer uses polyvinyl chloride, an ethylene-acetic acid-ethylene copolymer, polyvinylidene chloride, methyl vinyl silicone rubber and GNA chloroprene rubber as main materials to prepare a flame-retardation communication line by adding a compatibilizer, an oxidation agent, a flame-retardation system and the like. The synergistic effect is obvious, the antioxidant effect is good, the stability is high, and the flame-retardation effect is obvious, so that the cable fiber communication line has a broad application prospect.
