Product Description – GYTA33 Underwater Fiber Optic Cable

The GYTA33 fiber optic cable is specially designed for underwater and direct-buried installations in harsh environments. With steel wire armoring and a double jacket structure, this cable delivers excellent durability and reliability even under extreme conditions.

• Fiber Type: G652D Single-Mode (SM)

• Core Count: 12 Cores (customizable up to 144 cores)

• Structure: Stranded loose tube with secondary excess length design

• Armoring: Heavy-duty steel wire armor for superior mechanical protection

Key Features

• Underwater & Underground Use – Ideal for submarine shallow water, river crossing, and direct burial in demanding terrains.

• High Mechanical Strength – Steel wire armor ensures resistance to tensile force, crush, and impact.

• Loose Tube Design – Allows fibers to move freely inside the tube, reducing stress during cable stretching and ensuring long-term stability.

• Double Jacket Protection – Provides enhanced environmental resistance against moisture, corrosion, and soil pressure.

• Long Service Life – Built to perform reliably in telecom networks, power grid communication, and oil & gas projects.

Applications

• Submarine and river-crossing communication lines

• Direct buried underground fiber optic networks

• Backbone transmission for telecom operators

• Oil, gas, and power industries requiring secure communication links
