Gyts33 optical cable

GYTS33 is a steel-tape armored optical fiber cable designed for underwater and shallow water installations, providing robust protection and reliable transmission.

Overview and Applications

The GYTS33 cable is primarily used for underwater or shallow water installations, such as rivers, lakes, or coastal areas, where short-distance communication is required without the need for junctions . Its design allows it to be directly laid under water, making it suitable for environments where mechanical protection and water resistance are critical .

Construction Features

• Core and Strength Member: The cable core contains optical fibers housed in a tube filled with a waterproof compound. A central steel wire serves as the metal strength member, providing tensile strength .
• Armoring: A corrugated steel tape is applied around the core to prevent water ingress and enhance mechanical protection. This is followed by a polyethylene inner sheath .
• Flexibility: The cable is designed with a minimum bending radius and can withstand tension and crush forces, ensuring durability during installation and operation .
• Customization: Fiber types and cable parameters can be tailored according to customer requirements, including diameter and attenuation specifications .

Technical Specifications

• Attenuation: Typical values are provided in dB/km, depending on the fiber type used .
• Mechanical Strength: Maximum tension and crush resistance are specified to ensure safe handling and deployment .
• Environmental Suitability: The cable is resistant to water ingress and suitable for freshwater and shallow water environments .

Compliance and Standards

While GYTS33 is a manufacturer-specific designation, its optical fibers and cable design generally comply with ITU-T G-series Recommendations, particularly the G.65x series for single-mode fibers. These standards define transmission characteristics, environmental performance, and material properties for optical fiber cables . Supplement 47 of ITU-T G-series provides guidance on attenuation, chromatic dispersion, and practical deployment conditions, which are relevant for GYTS33 applications .

Summary

GYTS33 is a robust, steel-tape armored optical fiber cable optimized for underwater and shallow water installations. Its design ensures mechanical protection, water resistance, and reliable signal transmission, while its fibers can meet ITU-T standards for single-mode optical communication. The cable is versatile, with customizable parameters to suit specific deployment requirements .
