From industry inception up until the past five to ten years, buffer tube gels provided a critical waterblocking function for the majority of fiber optic cables deployed in the field. Old timers may recall that cable cores were once water-blocked with gels, in addition to gels placed in cable buffer tubes. In an effort to help reduce overall deployment costs and improve our customers’ installation efficiency, OFS developed gel-free cables, and the industry followed suit by introducing super-absorbent polymers (SAP) into fiber optic cable designs. Customers have wholeheartedly endorsed gel-free cables, and have deployed these products both aerially and underground over the past decade with resounding success. In fact, gel-free cables are used more often today than gel-filled cables.|From industry inception up until the past five to ten years, buffer tube gels provided a critical waterblocking function for the majority of fiber optic cables deployed in the field.
