Title: Plastic fiber-optic cable and producing method for the same

Abstract: A clad is produced by polymerizing methyl methacrylate and (meth)acrylic acid ester having alicyclic hydrocarbon group. A core is produced by an interfacial-gel-polymerization method. A first covering layer having a thickness being less than 500 .mu.m is formed on an outer surface of the clad to produce a single-fiber optical cable. A plurality of the single-fiber optical cables are bundled. A gap between the single-fiber optical cables is infused with a filler. The bundled single-fiber optical cables are covered with a second covering layer to produce a multi-fiber optical cable. Since the covering layer is thin, the multi-fiber optical cable has excellent flexibility and reduced bending loss.
