摘要: A fiber optic cable (10) includes a cable core (20) and a jacket section (30). Cable core (20) includes a central member (21), buffer tubes (23, 26), and optical fibers (22, 25) in respective buffer tubes. Jacket section (30) includes a tape layer (34) with a seam (35), and a seam guard (40) disposed over seam (35). Seam guard (40) is operative to perform dual functions, as the seam guard includes substrate (42) operative to prevent cable zippering, and a waterblocker (44) operative to inhibit the migration of moisture into cable core (20).
