Fiber optic overhead ground wire cables and processes for the manufacturing thereof |
摘要 |
A process for manufacturing fiber optic overhead ground wire cable may include: providing an optical core; providing a reinforcing structure consisting of at least one layer of wires onto the optical core, wherein at least part of the wires are clad with first metallic material; extruding an outer layer onto the reinforcing structure, wherein the outer layer is made of second metallic material having a softening point substantially similar to a softening point of the first metallic material; and cooling the outer layer immediately after extruding the outer layer. A fiber optic overhead ground wire cable may include: an optical core comprising a plurality of optical fibers housed in an inner tube; and a reinforcing structure consisting of at least one layer of wires stranded onto the optical core. The cable may be substantially devoid of interstices between the at least one layer of wires and the inner tube. |

1. A process for manufacturing fiber optic overhead ground wire cable, the process comprising:
providing an optical core; providing a reinforcing structure consisting of at least one layer of wires onto the optical core, wherein at least part of the wires are clad with first metallic material; extruding an outer layer onto the reinforcing structure, wherein the outer layer is made of second metallic material having a softening point substantially similar to a softening point of the first metallic material; and cooling the outer layer immediately after extruding the outer layer. |
