Abstract

A method for manufacturing a coated fiber optic cable is described herein. The method may include providing an inner jacket around a cable core, treating at least a portion of an exterior surface of the inner jacket with an adhesion-promoting treatment, and providing an outer jacket around the inner jacket. The cable core may include one or more optical fibers and may move in a downstream direction while the inner jacket and outer jacket are applied. The adhesion-promoting treatment may include a flame treatment, plasma treatment, or combinations thereof. The inner jacket may be applied upstream of the adhesion-promoting treatment and the outer jacket may be applied downstream of the adhesion-promoting treatment. The inner jacket and outer jacket may be chemically bound to one another in at least a portion of the interface of the outer jacket and inner jacket.

COATED FIBER OPTIC CABLES AND METHODS AND SYSTEMS FOR MANUFACTURING THE SAME

ABSTRACT

A method for manufacturing a coated fiber optic cable is described herein. The method may include providing an inner jacket around a cable core, treating at least a portion of an exterior surface of the inner jacket with an adhesion-promoting treatment, and providing an outer jacket around the inner jacket. The cable core may include one or more optical fibers and may move in a downstream direction while the inner jacket and outer jacket are applied. The adhesion-promoting treatment may include a flame treatment, plasma treatment, or combinations thereof. The inner jacket may be applied upstream of the adhesion-promoting treatment and the outer jacket may be applied downstream of the adhesion-promoting treatment. The inner jacket and outer jacket may be chemically bound to one another in at least a portion of the interface of the outer jacket and inner jacket.

BACKGROUND &SUMMARY

[0001]The disclosure relates generally to fiber optic cables and, more particularly, to coated fiber optic cables and systems and methods for the manufacture of coated fiber optic cables. One embodiment of the disclosure relates to a method for manufacturing a coated fiber optic cable. The method may comprise providing an inner jacket around a cable core, treating at least a portion of an exterior surface of the inner jacket with an adhesion- promoting treatment, and providing an outer jacket around the inner jacket. The cable core may comprise one or more optical fibers. The adhesion-promoting treatment may comprise a flame treatment, plasma treatment, or combinations thereof. The cable core may move in a downstream direction while the inner jacket and outer jacket may be applied. The inner jacket may be applied upstream of the adhesion-promoting treatment and the outer jacket may be applied downstream of the adhesion-promoting treatment. The exterior surface of the inner jacket may be in direct contact with an interior surface of the outer jacket at an interface of the outer jacket and inner jacket. The inner jacket and outer jacket may be chemically bound to one another in at least a portion of the interface of the outer jacket and inner jacket.
[0002]An additional embodiment of the disclosure relates to a coated fiber optic cable. The coated fiber optic cable may comprise a cable core, an inner jacket, and an outer jacket.

The cable core may comprise one or more optical fibers. The inner jacket may be positioned around the cable core. The exterior surface of the inner jacket may be in direct contact with an interior surface of the outer jacket at an interface of the outer jacket and inner jacket. The inner jacket and outer jacket may be chemically bound to one another in at least a portion of the interface of the outer jacket and inner jacket. The inner jacket may comprise an oxidized layer at the interface of the outer jacket and inner...
