摘要:
A fiber optic cable (40,50) having a cellularized cable component (10,10',10"), the cellularized cable component including at least one optical fiber and a cable jacket (45,55). The cable jacket can include surface irregularities (46,56) having crests and hollows (46a,46b;56a,56b) for reducing surface-to-surface contact with a surface (60) in the cable passage way. The cable jacket can include a friction reducing additive for lubricating the interface between the cable jacket and the cable passageway or objects in the cable passageway. A method and apparatus for producing the cables is also disclosed.
摘要:
A fiber optic cable product is provided that includes a strength member and an elongate cable core surrounding and mechanically coupled to the strength member. The cable core defines a number of lengthwise extending slots for receiving optical fibers and a number of voids proximate the strength member that also typically extend lengthwise therethrough. The fiber optic cable product is therefore relatively lightweight and flexible. In order to insure that the mechanical properties of the fiber optic cable product are uniform, the cable core typically defines the voids in a generally symmetrical manner about the central strength member. A method and an apparatus for extruding a fiber optic cable product that includes a cable core defining a plurality of voids are also disclosed.
