Fiber optic cables and stranded cables

Stranded fiber optic cables include ADSS, OPGW, and GYTS, designed for outdoor, aerial, and high-tension applications. Common Stranded Fiber Optic Cable Types1.

ADS

S (All-Dielectric Self-Supporting) ADSS cables are stranded, non-metallic fiber optic cables designed for installation on power transmission lines. They use high-modulus aramid yarns to provide tensile strength, allowing the cable to span long distances without support while resisting ice, wind, and electromagnetic interference from high-voltage lines. 2.

OPG

W (Optical Ground Wire) OPGW combines the functions of a grounding wire and fiber optic backbone. It is a stranded cable with metallic outer layers that protect the fibers inside while serving as a lightning shield for high-voltage towers. 3.

GYT

S (Outdoor Stranded Loose Tube - Steel) GYTS cables are stranded loose tube cables with a corrugated steel tape (CST) armor. They are widely used in outdoor telecommunications for direct burial or conduit installations, providing mechanical protection and water-blocking capabilities. Additional Notes on Stranded ConstructionStranded fiber optic cables typically include: Loose tubes containing multiple fibers, isolating them from tension and environmental stressStrength members such as aramid yarn or fiberglass rods to absorb pulling forcesOuter jackets that protect against moisture, UV, and mechanical damage These cables are ideal for aerial, industrial, and outdoor deployments where flexibility, tensile strength, and environmental resistance are critical.

By selecting the appropriate stranded fiber optic cable, network designers can ensure durability, high bandwidth, and reliable performance in challenging outdoor or high-tension environments.
