Corning ALTOS® loose tube, double-jacket, single-armour cables with polyamide overcoat are designed for outdoor use where resistance against hydrocarbons such as oil and gas as well as resistance against termites is required.
By using polyamide instead of a heavy lead sheath, these cables are easier to handle and install. Therefore, they are less hazardous for personal health and for the environment.
In addition, the corrugated steel tape armouring used for light duty and heavy duty industrial direct buried applications reduces the risk of inadvertent fibre damage protecting the cables against rodents and preventing network failures. The high-density polyethylene (HDPE) inner and middle jacket with extra aramid yarns provide extra protection and a high tensile strength and crush resistance allowing the cables to be installed where they are exposed to higher vertical forces.
An extra aluminium tape around the cable core protects these cables against the penetration of moisture or chemicals and builds extra security for the network infrastructure.
