Abstract
An optical communication cable subassembly includes a cable core having optical fibers each comprising a core surrounded by a cladding, buffer tubes surrounding subsets of the optical fibers, and a binder film surrounding the buffer tubes. Armor surrounds the cable core, the binder film is bonded to an interior of the armor, and water-absorbing powder particles are provided on an interior surface of the binder film.
Claims7
An optical communication cable, comprising:
- a core of the cable, comprising:
- optical fibers;
- buffer tubes surrounding subsets of the optical fibers;
- and
- a central strength member, wherein the buffer tubes are stranded around the central strength member in a pattern of stranding including reversals in lay direction of the buffer tubes;
- and
- a binder film to hold the buffer tubes in position around the central strength member,
- wherein using pull-through testing the binder film has a static friction force between the stranded buffer tubes and the central strength member of at least 10 N for a 100 millimeter length of the stranded buffer tubes.
