Abstract
In an optical cable consisting of a metallic core (1) with at least one channel (2), which extends in the longitudinal direction of the core (1) and in which at least one optical waveguide (13) is arranged, the at least one channel (2) is arranged within the sheath encasing the core (1) and is closed to the exterior.
Claims17
An optical cable comprising:
- a metallic core with at least one channel which extends in the longitudinal direction of the core, at least one optical waveguide being arranged in said channel,
- wherein said channel is within the core,
- wherein a thin-walled region is present between a portion of said channel and a portion of a peripheral surface of said core and said thin-walled region has a seam extending in a direction substantially parallel to the longitudinal axis of said channel and closes said channel, and
- wherein a narrow arch-shaped gap at the portion of the peripheral surface of the core is present above the thin-walled region.
A method of producing an optical cable comprised of a metallic core containing at least one channel in which at least one optical waveguide is arranged, said method comprising:
- first producing by extrusion a metallic circular profile with a closed channel extending in the longitudinal direction of the circular profile and arranged eccentrically relative to the center of the circular profile;
- and
- opening said channel at a thin-walled region of said metallic core, inserting at least one optical waveguide into said channel, and closing said channel.
An optical cable comprising:
- a metallic core containing at least one channel extending in said core's longitudinal direction;
- at least one optical waveguide arranged inside said channel;
- and
- a thin-walled region present between a portion of said channel and a portion of a peripheral surface of said core, said thin-walled region having a seam extending in a direction substantially parallel to the longitudinal axis of said channel, and
- wherein a narrow arch-shaped gap at the portion of said peripheral surface of the core is present above the thin-walled region.
A method of producing an optical cable comprised of a metallic core containing at least one channel extending in said core's longitudinal direction, and at least one optical waveguide arranged in said channel, said method comprising:
- producing by extrusion a metallic profile with said channel, said channel being closed and arranged eccentrically relative to the center of the profile;
- opening said channel at a thin-walled region present between a portion of said channel and a portion of a peripheral surface of said channel;
- and
- inserting said at least one optical waveguide into said channel.
An optical cable comprising:
- metallic core means for containing at least one channel means extending in the core's longitudinal direction;
- and
- said channel means for containing at least one optical waveguide,
- wherein a thin-walled region is present between a portion of said channel means and a portion of a peripheral surface of said metallic core means and said thin-walled region has a seam extending in a direction substantially parallel to the longitudinal axis of said channel means, and
- wherein a narrow arch-shaped gap at the portion of the peripheral surface of the core is present above the thin-walled region.
