1. An optical cable, comprising:
- a waveguide;
a protective sleeve surrounding the waveguide;
an intermediate layer surrounding the protective sleeve and having tension-resistant elements; and
a cable sheath surrounding the intermediate layer and having a transitional area that faces an inner surface of the sheath and in which a material of the cable sheath is mixed with the tension-resistant elements of the intermediate layer, whereinthe transitional area comprises 0.1% to 20% of the thickness of the cable sheath.

Abstract
An optical cable comprises a tight-buffered optical cable and a protective sleeve which surrounds the tight-buffered optical cable. An intermediate layer surrounds the protective sleeve has tension-resistant elements. Furthermore, the optical cable contains a cable sheath which surrounds the intermediate layer, and a transitional area facing its inner surface. In this transitional area, the material of the cable sheath is mixed with the tension-resistant elements of the intermediate layer.

15. An optical cable, comprising:
-
a waveguide; a protective sleeve surrounding the waveguide forms a gap; an intermediate layer surrounding the protective sleeve and has tension-resistant elements; and a cable sheath around the intermediate layer and operatively connected to the protective sleeve via the intermediate layer such that any relative shrinkage of the protective sleeve and of the cable sheath with respect to the waveguide after 24 hours is not greater than 3 mm to 5 mm over a cable length of 3 m and at a temperature of approximately 80°
C.,wherein a withdrawal force of the protective sleeve from the cable sheath is in the range from 30 N to 60 N at room temperature and with a withdrawal speed in the range from 40 mm/min to 50 mm/min, over a cable length of 1 m. - View Dependent Claims (16, 17, 18, 19, 20)
