Dirrect duct underwater fiber optic cable GYTS33 double jacket

Dirrect duct underwater fiber optic cable GYTS33 double jacket

GYTS33 is an outdoor optical cable, which is mainly used for direct burial and underwater installation due to its strong moisture and rodent resistance. It is constructed with a central steel wire for strength. Surrounding this core is a bundle of loose tubes made from high-modulus plastic. Each tube houses multiple 250µm optical fibers and is filled with a water-resistant compound. These tubes are then stranded around the central strength member to form a compact, circular cable core .Double armored structure including steel tape and round steel wire armor protect against mechanical impact and rodents.Double UV-resistant polyethylene (PE) Jacket design are perfect for outdoor durability.

Features:

· Rodent and water Resistance: The optical fibers are enclosed in loose tubes filled with a waterproof compound. The outer layer of round steel wire armor and inner layer of steel tape further enhance the cable's resistance to water ingress and makes it resistant to damage from rodents, ensuring long-term stable operation of the optical fibers.

· Superior Tensile Strength: The steel wire within the cable contribute to its high tensile strength, enabling it to withstand significant pulling forces. This makes GYTS33 cables suitable for installation in various complex terrains and environments

· Strong Corrosion Resistance: The cable's outer and inner sheath is made of weather-resistant and corrosion-resistant polyethylene material, capable of withstanding various harsh environmental conditions and extending the cable's service life.

· Installation in harsh outdoor environments: Due to GYTS33 excellent corrosion, Rodent and water resistance and UV protection, it is ideal for direct duct and underwater use in harsh outdoor environments
