Waterproof Stern Cable GYJTA is designed for marine and outdoor environments where water resistance, durability, and protection against harsh conditions are essential. This cable is specifically engineered for underwater, coastal, and high-moisture applications, offering reliable performance even in challenging conditions.

Structure and Features

1. Optical Fibers:
   • 200μm or 250μm fibers are included, typically single-mode or multimode, depending on application requirements.
   • The fibers are placed in a loose tube made from a high-modulus plastic material, ensuring durability and flexibility.
2. Loose Tubes and Filling:
   • The loose tubes are filled with a water-resistant, gel-like filling compound to prevent water ingress and maintain signal integrity over time.
3. Strength Member:
   • A central non-metallic strength member such as Fiber Reinforced Plastic (FRP) provides the necessary tensile strength to support the cable’s integrity during installation and in harsh conditions.
   • This strength member helps resist stretching or damage to the cable core, enhancing long-term reliability.
4. Waterproofing and Protection:
   • The cable core is surrounded by a waterproofing layer to protect against environmental factors like moisture and chemicals.
   • A layer of waterproof tape and specialized water-blocking materials are longitudinally applied to prevent water from entering the cable core, even if the sheath is compromised.
5. Armoring:
   • For enhanced protection, the cable is armored with either a steel tape or other forms of metallic shielding, offering resistance to mechanical impacts, crushing, and rodent attacks.
6. Outer Sheath:
   • The final layer consists of a durable polyethylene (PE) or other weather-resistant materials that provide additional environmental protection.
   • The PE sheath ensures the cable is resistant to UV, saltwater, and other corrosive elements typically found in marine or outdoor settings.

Applications

• Marine Installations: Ideal for underwater applications, such as submarine cables or offshore platforms.
• Outdoor/Underground Installations: Suitable for environments exposed to high moisture or where robust protection against physical damage is needed.
• Coastal Areas and Wet Environments: Perfect for regions with frequent water exposure, ensuring long-lasting performance.

Advantages

• Waterproof: Designed to withstand prolonged exposure to water and moisture, ensuring signal integrity.
• High Durability: The combination of non-metallic strength members and armored protection provides superior resistance to physical damage.
• Long-term Reliability: With its special waterproofing features, the cable can be trusted for use in demanding marine and outdoor environments.
• Corrosion-resistant: Resistant to the effects of saltwater and other corrosive environmental factors.

The Waterproof Stern Cable GYJTA is a highly durable and reliable option for environments that demand robust performance in wet, harsh, and physically challenging conditions.
