Water blocking yarn is a swellable protective material used inside fiber optic cables to prevent water penetration along the cable length. It is commonly placed between buffer tubes, strength members, and outer jackets in outdoor, duct, and direct-buried cable designs. The fiber optic cable core is the physical glass medium that transports optical signals from an attached light source to a receiving device. Fiber optic cables are the backbone of modern communication networks, connecting the world with unparalleled speed and efficiency, thanks in no small part to the protective and strengthening role of aramid yarn.
