Description
GYXTA33 optical cable is designed with colored optical fibers housed in a loose tube made of high-modulus, water-resistant material, filled with thixotropic water-blocking gel for enhanced fiber protection. Surrounding the loose tube is a layer of fine circular steel wires twisted to create a compact, round cable core, with interstices filled with water-blocking material for additional moisture resistance. The cable is wrapped longitudinally with coated aluminum tape, extruded with a polyethylene inner sheath, armored with a single layer of fine circular steel wire, and finished with a durable polyethylene outer sheath, ensuring exceptional mechanical strength and environmental protection for a wide range of applications.
Feature
Cross-section Diagram
- Good mechanical performance and excellent temperature stability.
- Double-layer fine circular steel wire armor enhances tensile strength.
- Loose tube material provides high hydrolysis resistance and exceptional pressure resistance.
- Special grease inside the tube ensures crucial protection for optical fibers.
- Moisture-resistant coated aluminum tape offers enhanced durability.
- Compact size, lightweight design, and easy installation.
Application Scenario
The GYXTA33 cable ensures consistent performance across various demanding scenarios, providing a dependable solution for modern communication needs.
- Direct-Burial Installations: The cable's steel wire armor provides high tensile strength and crush resistance, making it ideal for direct burial without additional protective conduits.
- Underwater and Subterranean Deployments: Designed to withstand sub-aquatic pressure, the GYXTA33 is suitable for installations beneath rivers, lakes, or other water bodies, as well as deep underground pathways.
- Long-Distance Communication Networks: Its low attenuation and chromatic dispersion characteristics make it suitable for long-haul transmission in backbone networks.
Delivery
Recommended Delivery Length: 2000m.
Other lengths can be provided according to customer requirements.
