    Abstract: Optical cable has a fiber core (1) and fiber cladding (2) adhered with inner and outer external layers (3,4) respectively comprising molding compositions (A and B) having polyamides (I,II). (A) has zero-shear viscosity of 400-6000 Pas at 220 degreesC. (B) further contains flame retardant and impact modifier. Amount of polyamide (II) (a), flame retardant (b) and impact modifier (c) is based on total amount of (a,b,c). An optical cable comprises a polymer optical conductor comprising a fiber core (1) and a single layer or multi-layer fiber cladding (2) which is adhered with inner external layer (3) with a peel force of at least 50 N and an outer external layer (4) adhered to inner external layer with peel force of 30N or less. The inner and outer external layers respectively comprise molding compositions (A and B) containing polyamides (I,II). Polyamide (I) is selected from PA 11, PA 12, PA 1012, PA 1212, copolyamide of at least 2 of PA 11, PA 12, PA 1012, PA 1212 containing not more than 30 mol% of comonomer, and their mixtures, and contains at least 50 micro-eq/g of amino end groups. Composition (A) has zero-shear viscosity of 400-6000 Pas according to ASTM D 4440 at 220 degreesC. The polyamide (II) is selected from PA 11, PA 12, PA 1012, PA 1212, copolyamide of at least 2 of PA 11, PA 12, PA 1012, PA 1212 containing not more than 30 mol% of comonomer, polyetheramide of the above polymers, and their mixtures. Composition (B) further contains 5-45 wt.% of a flame retardant and 0-60 wt.% of an impact modifier. The amount of polyamide (II), flame retardant and impact modifier is based on total amount of polyamide (II), flame retardant and impact modifier.
